kungfu vs fastapi_mcp
kungfu: Kungfu keeps a unit of Work outside any single agent session, recording its objective, progress, evidence, next action and completion state, so the same Work can move between Codex, Claude, OpenCode, Amp or your own agent without re-explaining context. Each Agent attempt is recorded under the Work, a second live writer is blocked, and an Agent cannot approve its own result: completion goes through independent review. It is in Alpha.; 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.
TL;DR
Switching between a premium and a cheaper coding agent on the same task
- 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.
- 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).
