fastapi_mcp vs deepseek-pp

Q: Which is better, fastapi_mcp or deepseek-pp?

By GitHub stars, fastapi_mcp has more community adoption, but the best choice depends on your specific use case.

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.; deepseek-pp: DeepSeek++ is a browser extension for Chrome, Edge, and Firefox that injects native-style tool calling, an MCP tool system, long-term memory, skill presets, and automated task scheduling into the DeepSeek web interface. It intercepts the SSE response stream in real time to execute tool calls transparently, giving DeepSeek persistent cross-session memory and agent-like automation without API access.

TL;DR

fastapi_mcpDev Tooling · ★ 12.0k

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).
