About:
FastMCP is a high-performance Python framework for creating Model Context Protocol (MCP) servers and clients. It provides an intuitive, Pythonic API that simplifies the integration of AI models with external tools and data sources. The framework focuses on speed and developer experience, enabling rapid development of robust AI-connected applications.
Key Features:
  • High-performance async architecture
  • Pythonic and intuitive API design
  • Built-in client and server implementations
  • Seamless integration with Python ecosystem
Use Cases:
  • Building custom AI tool servers for LLMs
  • Creating MCP clients to connect to external services
  • Rapid prototyping of AI-enhanced applications
  • Integrating existing Python codebases with AI models
Alternatives:
  • mcp – Official MCP reference implementation, more verbose than FastMCP
  • langchain – Broader AI framework, heavier than FastMCP's focused MCP tooling
