What is an MCP Server?

An MCP server is a small program that exposes a set of tools to an AI assistant. When you ask Claude to "search the web" or "read this PDF", it calls the appropriate MCP tool behind the scenes.

The protocol is:

Open — any developer can build an MCP server
Portable — works with Claude, Cursor, Gemini CLI, OpenClaw, and more
Composable — combine multiple servers to build powerful workflows
