Model Context Protocol Python SDK

Facilitates the building of Model Context Protocol (MCP) clients and servers using Python.

About

The Model Context Protocol Python SDK provides a comprehensive framework for developing applications that seamlessly integrate with Large Language Models (LLMs). It simplifies the process of creating both MCP clients, enabling connection to any MCP server, and MCP servers, capable of exposing resources, prompts, and tools. The SDK supports standard transports like stdio and SSE, handling MCP protocol messages and lifecycle events, thus streamlining the development of LLM-powered applications.
