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`
**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...

- 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

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...

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):

- 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...

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...

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...

Docker needs sudo+password. Let me verify the auth changes are correct by testing the logic directly:
Bash
Unit test the auth middleware logic
IN
node - << 'EOF'
// Simulate the auth middleware logic
const [ENV_SECRET];
process.env.API_KEY = API_KEY;
const { authentikMiddleware } = require('/volume2/docker/finance/finance-hub/backend/src/auth.js');
function testReq(path, headers = {}) {
const res = { status(code) { this.code = code; return this; }, json(body) { return body; } };
const req = { path, headers };
let passed = false;
authentikMiddleware(req, res, () => { passed = true; });
return { passed, code: res.code, user: req.user };
}
// Public path — no auth needed
let r = testReq('/api/health', {});
console.assert(r.passed, 'health should be public');
console.log('✓ /api/health is public');
// Valid API key
r = testReq('/api/payments', { authorization: `Bearer ${API_KEY}` });
console.assert(r.passed, 'valid key should pass');
console.assert(r.user.username === 'api-key', 'api user');
console.log('✓ valid API key passes');
// Wrong API key
r = testReq('/api/payments', { authorization: 'Bearer wrongkey' });
console.assert(!r.passed, 'wrong key should fail');
console.assert(r.code === 401, '401 on bad key');
console.log('✓ wrong API key returns 401');
// No auth + no bypass + no authentik header
process.env.DEV_BYPASS_AUTH = 'false';
r = testReq('/api/payments', {});
console.assert(!r.passed && r.code === 401, 'no creds → 401');
console.log('✓ no credentials returns 401');
// Upload endpoints no longer public
r = testReq('/api/upload/csv', {});
console.assert(!r.passed && r.code === 401, 'upload/csv requires auth');
console.log('✓ /api/upload/csv now requires auth (was public, now fixed)');
// Authentik header pass-through
r = testReq('/api/payments', { 'x-authentik-username': 'lukastest', 'x-authentik-email': '[EMAIL]' });
console.assert(r.passed && r.user.username === 'lukastest', 'authentik header works');
console.log('✓ Authentik X-authentik-username header works');
console.log('\nAll auth tests passed.');
EOF

All auth tests passed.
All auth cases pass. Now test the MCP spending_by_tag tool against the live backend (with DEV_BYPASS_AUTH still on):
Bash

MCP tools work correctly against real data. Let me write the Claude desktop config example and the
.gitignore
for the mcp dir:
Write
claude_desktop_config.example.json
claude_desktop_config.example.json

}
}
}
}
Write
.gitignore
.gitignore

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...
