MCP Server SDK

A standardized toolkit for building secure, interoperable interfaces between LLMs and local data sources (tools, files, and databases).

The MCP Server SDK (available in TypeScript and Python) provides a production-ready framework for exposing local resources to AI models like Claude. It implements the Model Context Protocol: an open standard that replaces fragmented integrations with a unified architecture. Developers use these SDKs to build servers that grant LLMs real-time access to specific environments (Google Drive, Slack, or local SQLite databases). The SDK manages the transport layer via JSON-RPC 2.0 and handles lifecycle events: ensuring secure, predictable communication. It currently supports core integrations for high-performance IDEs including Cursor and Zed.
