console.assert(r.code === 401, '401 on bad key');

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config....

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:

Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (

Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:

Bug fixed:
/api/upload/csv
and

/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in

for production.

Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

description: Architecture, auth design, API key, MCP server location and tools for the finance-hub project
type: project
---
Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed

Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →
401
immediately (no fallthrough). This is what the MCP server and scripts use.

lets work on authentication. I want to be able to connect using authentik. REveiw copy of the project in auth folder. Lets test it and establish security. There should be simple way to reauthorize automatically for api and also there should be claude chat compatible mcp with autorization that si stable. Think about it test it and then provide suggestions

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub with the Authentik NPM nginx snippet (see `/volume2/docker/finance/auth/README.md`).
**Why:** Application had no production auth despite Authentik being available and running.
**How to apply:** When asked about enabling auth or going to production, walk through NPM proxy + Authentik outpost steps from the README. API_KEY is already set for MCP.
Here's a full summary of what was done and the findings:
What was built and fixed
What was built and fixed
Security fixes
Security fixes
Bug fixed:
/api/upload/csv
and
/api/upload/preview
were in
PUBLIC_PATHS
— anyone on the network could upload files without authentication. Both are now protected. Only
/api/health
and
/api/payments/ingest
remain public.
CORS restriction added:
index.js
now reads
CORS_ORIGIN
from env. Set it to your frontend domain (e.g.
https://finance.lakylak.xyz
) in
.env
for production.
API key auth layer (backend/src/auth.js)
API key auth layer (
backend/src/auth.js
backend/src/auth.js
)
Requests with
Authorization: Bearer <key>
are now validated before the Authentik header check. Set
API_KEY=
in
.env
(already has a generated key). Wrong key →

**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Update Todos
Fix auth.js: add API key support + remove upload endpoints from PUBLIC_PATHS
Update index.js: add CORS origin restriction via env var
Update .env and .env.example with API_KEY variable
Build MCP server (stdio, Claude desktop compatible)
Test: restart backend, verify API key auth and MCP connection

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...

Finance Hub is a personal finance tracker at `/volume2/docker/finance/finance-hub/`.
**Running services** (as of 2026-05-09):
- Backend: port 3001 (Express/Prisma, PostgreSQL)
- Frontend: port 5175 (React/Vite)
- Adminer: port 8092
- Authentik: port 9100 (auth.lakylak.xyz, tag 2026.2.1)
**Auth design:**
- Production: NPM (Nginx Proxy Manager) + Authentik forward-auth outpost → injects `X-authentik-username` header
- `DEV_BYPASS_AUTH=true` is currently set in `.env` — app runs without real auth
- API key auth added: `Authorization: Bearer <API_KEY>` bypasses Authentik header check (used by MCP/scripts)
- API_KEY in `.env`: `94bb2917b9a1b9dcbaec49e7009c2a6b222fc310d32f530aa07e411e8d4a058c`
**Public endpoints** (no auth): `/api/health`, `/api/payments/ingest`
**Security fix applied (2026-05-09):** Removed `/api/upload/csv` and `/api/upload/preview` from PUBLIC_PATHS — they were incorrectly public.
**MCP server:** `/volume2/docker/finance/finance-hub/mcp/server.js`
- Stdio transport, works with Claude desktop
- Tools: list_transactions, spending_by_tag, get_transaction, list_tags, add_tag, remove_tag, health_check
- Env: FINANCE_HUB_URL, FINANCE_HUB_API_KEY
- Config example: `mcp/claude_desktop_config.example.json`
**To enable real Authentik auth:** Set `DEV_BYPASS_AUTH=false` in `.env`, configure NPM proxy host for finance-hub w...
