PrefectHQ/fastmcp
🚀 The fast, Pythonic way to build MCP servers and clients.
This project helps Python developers build applications that connect Large Language Models (LLMs) to custom tools and data. You provide Python functions, and it automatically generates the necessary components for LLMs to use them. This is ideal for developers who want to integrate LLMs with existing business logic or data sources efficiently.
23,593 stars. Used by 254 other packages. Actively maintained with 206 commits in the last 30 days. Available on PyPI.
Use this if you are a Python developer who needs to expose custom functions, resources, or prompts to an LLM via the Model Context Protocol (MCP) and want to streamline server and client creation.
Not ideal if you are not a Python developer or are looking for a no-code solution to connect LLMs to tools.
