Overview

FastMCP is a Python framework for building Model Context Protocol (MCP) servers and clients with minimal boilerplate. It provides decorators and utilities to define MCP tools, resources, and prompts in a straightforward, Pythonic style. Designed for rapid development of MCP integrations without verbose configuration.

Best for
Python developers building LLM integrations who want to expose tools and data sources via the Model Context Protocol without writing boilerplate.

Use cases

Building MCP servers that expose Python functions as tools for Claude or other LLMs
Creating MCP clients that connect to multiple servers and aggregate their capabilities
Prototyping LLM integrations with custom data sources or business logic

How to use

Install

uv pip install fastmcp

Pros

Low boilerplate. Decorator-based API reduces setup friction compared to manual MCP implementation
Python-native. Leverages familiar Python patterns and async/await for developers already in the ecosystem
Active community. 25k+ stars indicates adoption and ongoing maintenance

Cons

Python-only. Not suitable for teams or projects requiring other languages
MCP specification dependency. Requires understanding of MCP protocol; not a general-purpose framework
Maturity unknown. Early-stage tooling may have breaking changes or incomplete feature coverage
