mymir vs fastapi_mcp

mymir: Mymir replaces the cycle of agents having no memory by providing a context network and retrieval interface. It manages the full lifecycle from brainstorming to execution, allowing agents to walk into every session knowing exactly what to do next. Built as a Claude Code plugin, it automatically provides stage-appropriate context and tracks progress.; 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).
