When to choose:

You already have a FastAPI application and want to expose its endpoints as MCP tools while reusing your existing FastAPI authentication dependencies and Swagger schemas.
You want to mount the MCP server directly onto your ASGI app or deploy it separately under an MIT license.

When to skip:

You are building a standalone MCP server from scratch rather than wrapping a FastAPI app; use FastMCP or the official MCP Python SDK.
You need an actively updated repository (last push was November 2025).
