MCP (Model Context Protocol) is the emerging standard to define how AI agents communicate with applications. Using FastAPI-MCP, creating a secured MCP server to your application takes only 3 lines of code: 
from fastapi import FastAPI
from fastapi_mcp import FastApiMCP

app = FastAPI()

mcp = FastApiMCP(app)
mcp.mount_http()
That’s it! Your auto-generated MCP server is now available at https://app.base.url/mcp

​
