OnionClaw vs fastapi_mcp
OnionClaw: OnionClaw is an OpenClaw skill and standalone tool that enables AI agents to access the Tor network and .onion hidden services. It provides seven commands for dark web OSINT, including search, fetch, and analysis. The tool runs as a drop-in skill for OpenClaw or standalone from the terminal.; 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).
