fastmcp as a fastapi extension

[mconflitti-pbc]

To reduce duplication when exposing functionality from an API, I see it immensely useful to be able to tack on this protocol to an existing fastapi (maybe others) by means of a decorator or extension to fastapi.

from fastapi import FastAPI
from fastmcp import FastMCP, FastAPIWrapper


mcp = FastMCP("Demo 🚀")
app = FastAPIWrapper(FastAPI(), mcp)


@app.get("/") # <<< internally does normal fastapi stuff + @mcp.tool()
async def root():
    return {"message": "Hello World"}
