mcp-migrate vs fastapi_mcp

mcp-migrate: `mcp-migrate` is a command-line utility designed to identify and automatically fix breaking changes in server code introduced by the MCP 2026-07-28 protocol specification. It acts as a static analysis and code modification tool, offering checks, automated fixes, and integration with development workflows.; fastapi_mcp: FastAPI-MCP allows you to expose your existing FastAPI endpoints as Model Context Protocol (MCP) tools. It offers native integration with FastAPI, including built-in authentication using existing dependencies, and preserves schemas and documentation.

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).
