## Quick reference

* **Source layout**: `src/server.ts` is the process entrypoint; HTTP routes live in `src/routes/index.ts`. See [Architecture](/development/architecture) for the full map.
* **Dev servers**: `pnpm dev` runs the backend on `:3000` and the Vite frontend on `:5173`. The frontend proxies `/api`, `/mcp`, `/sse`, `/oauth`, `/health` to the backend (`frontend/vite.config.ts`).
* **Tests**: `pnpm test` runs the Jest suite. Tests live under `src/**/*.test.ts` and `tests/`.
* **Lint / format**: `pnpm lint`, `pnpm format`.
* **Storage modes**: file (default, `mcp_settings.json`) or PostgreSQL — see [Database Configuration](/configuration/database-configuration).

For deployment, dependencies, and full end-user installation, see [Installation Guide](/installation).
