FastMCP Documentation
by Prefect / Jeremiah Lowin
The fast, Pythonic way to build MCP servers and clients.
Overview
FastMCP is a Python framework described as the fast, Pythonic way to build MCP servers, clients, and applications; its 1.0 version was incorporated into the official MCP Python SDK, and the actively maintained standalone project powers a large share of MCP servers. The docs at gofastmcp.com cover three pillars: Servers (exposing tools, resources, and prompts to LLMs, with schemas, validation, and docs auto-generated from decorated Python functions), Clients (connecting to any MCP server, local or remote, programmatic or CLI), and Apps (interactive UIs rendered directly in the conversation). The documentation includes installation, quickstarts, advanced patterns, and production deployment guidance, and is itself available as an MCP server and in llms.txt/markdown formats.
