Open protocol for connecting AI models to external tools and data sources.

About

The Model Context Protocol is an open standard for connecting AI models to external tools, data sources, and services. Think of it as USB-C for AI — a universal interface that lets any model talk to any tool.

MCP defines a simple JSON-RPC protocol for tool discovery, execution, and result handling. It's supported by Anthropic, and integrated into Claude Code, Cursor, and a growing ecosystem of MCP servers.
