oh-my-hermes vs fastapi_mcp

oh-my-hermes: oh-my-hermes (OMH) is an operating layer that sits above Nous Research's Hermes Agent without replacing it. It frames a request, picks a workflow and evidence gates, and runs Hermes-native skills inside that path, covering planning, research, creation, coding handoffs, operations and project memory. The omh CLI handles setup, updates, health checks and per-category model selection, and installs via a shell script, Homebrew, Bun, npm or a Hermes skill tap.; 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).
