threejs-devtools-mcp vs fastapi_mcp
threejs-devtools-mcp: threejs-devtools-mcp is an MCP server offering a comprehensive suite of 69 tools for real-time inspection and live modification of Three.js scenes. It supports both vanilla Three.js and React Three Fiber projects, allowing developers to debug, audit, and generate code without altering their project files.; 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).
