Q: Which is better, claude-delegator or fastapi_mcp?

By GitHub stars, fastapi_mcp has more community adoption, but the best choice depends on your specific use case.

claude-delegator: Claude Delegator is a plugin for Claude Code that enables external model second opinions, multi-provider advisory review, and arbiter-mediated consensus across GPT (Codex), Gemini, Grok, and Claude. It includes seven expert roles (Architect, Plan Reviewer, ect.) that can run in advisory or implementation mode, single-shot or multi-turn.; 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).
