[Repo] modelcontextprotocol/python-sdk: The official Python SDK for Model Context Protocol servers and clients

The official Python SDK for Model Context Protocol (MCP) servers and clients, enabling developers to build AI agent applications with standardized protocol support. This highly-starred repository (21.9k stars) provides comprehensive tools for implementing MCP-compliant servers and clients in Python.

Key Points

• •Model Context Protocol (MCP) is a standardized protocol for connecting AI models with external tools and data sources
• •The Python SDK provides official libraries for building both MCP servers and clients in Python
• •Enables seamless integration between language models and custom applications, APIs, and data sources
• •Supports bidirectional communication allowing models to request tools and receive structured responses
• •Actively maintained with recent updates (last pushed March 2026) indicating ongoing development and support
• •High community adoption with 21,996 stars indicating strong ecosystem interest and reliability
• •Simplifies implementation of tool-use patterns for AI agents without building protocol from scratch
• •Provides standardized interfaces for defining resources, tools, and prompts that models can access
