Use it only if these specific tools contribute to your workflow. ## When NOT to use fastapi_mcp - If your project strictly uses non-Python languages or frameworks that are not compatible with FastAPI and do not require integration with the Model Context Protocol (MCP). - When you seek broader support outside MCP protocol, as this tool confines its utility specifically to applications needing MCP compatibility. ## Common questions ### What is the difference between mcp-unity and fastapi_mcp? mcp-unity: MCP plugin for Unity Editor enabling integration with various LLM tools. fastapi_mcp: Expose FastAPI endpoints as MCP tools with authentication.
