Welcome to FastMCP

FastMCP is the standard framework for working with the Model Context Protocol (MCP).
FastMCP automates schema, validation, and documentation generation for tools declared with Python functions.
It handles transport negotiation, authentication, and protocol lifecycle when connecting to a server.
FastMCP 1.0 was incorporated into the official MCP Python SDK in 2024.
The standalone project is downloaded a million times a day and powers 70% of MCP servers across all languages.
FastMCP has three pillars: Servers (expose tools to LLMs), Apps (interactive UIs), and Clients (connect to MCP servers).
FastMCP documentation is available in LLM-friendly formats, including MCP server access, llms.txt, and markdown.
