open-mcp-apps vs fastapi_mcp
open-mcp-apps: open-mcp-apps is an open engine built on MCP Apps, extending the Model Context Protocol to provide AI agents with a persistent, reusable user interface. It enables AI to author, save, and manage single-file HTML applications with versioned data, ensuring continuity across different chats and hosts.; 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).
