FastMCP is a Python framework for building Model Context Protocol (MCP) servers, clients, and interactive applications. It turns ordinary Python functions into MCP tools with automatic schema generation, validation, transport negotiation, and authentication.
Use cases
- build an mcp server in python
- expose python functions as llm tools
- connect an mcp client to a remote server
- add tools to claude desktop or cursor
- build interactive ui apps for mcp tools
- deploy a production mcp server with auth
- migrate mcp servers to the latest protocol version
When to choose
- you want the de facto standard, high-level Python API for MCP with best practices built in
- you need servers, clients, and interactive apps from one coherent framework
- you want automatic schema generation, validation, and transport handling
- you need protocol-version negotiation across MCP eras in one deployment
When to avoid
- you need a non-Python language (a separate TypeScript port exists)
- you only need the minimal low-level MCP SDK rather than a full framework
- you require a fully stable release of the newest major version (v4 is beta)
