MCP SDK

The MCP SDK provides the official, language-specific libraries (Python, TypeScript, Go) for building Model Context Protocol servers and clients, standardizing how LLMs access external tools and data.

The Model Context Protocol (MCP) SDK delivers the essential, language-specific tools—including official Python and TypeScript libraries—for developers to build robust AI integrations. This open-source standard, introduced by Anthropic and adopted by providers like OpenAI and Google DeepMind, solves the complex 'N×M' integration problem by providing a universal interface. Use the SDK to create MCP servers that securely expose data, tools, and prompts, and build MCP clients (AI applications) that connect to them. This enables AI agents to reliably perform tasks and access contextual information from external systems like Google Drive or GitHub.
