About fastapi_mcp
FastAPI MCP is an MIT licensed Python library from Tadata that exposes the endpoints of an existing FastAPI application as Model Context Protocol (MCP) tools, so MCP clients such as Claude and Cursor can call a team's own API, and it is built for Python backend developers who already run FastAPI services and want agent access without hand writing a separate MCP server.
