How does authentication work?

JWT tokens are used. Test users (e.g., `test@example.com` / `password123`) are loaded from fixtures. Tokens can be generated in the Rails console. A pre‑configured `.mcp.json` file with a long‑lived token is provided.

Where does the MCP server run?

The ActionMCP server runs as a standalone server on port `62770` (via `mcp.ru`). Nginx proxies `/mcp` requests to this server.
