What is MCP?

The Model Context Protocol is the open standard for connecting AI models to external tools and data — often called "USB-C for AI." Created by Anthropic, adopted by OpenAI, Google, Microsoft, and the Linux Foundation.

Build one MCP server, and every compatible AI client — Claude, ChatGPT, Copilot, Cursor — can use it. Over 10,000 servers exist, from database connectors to code analysis tools.
