01What is MCP

What are MCP and the Claude plugin

Your AIClaude · Cursor · Codex

MCP

The socket "standard"

A shared way (common rules) to connect an AI to outside data — like an outlet standard, so Claude and Cursor use the same socket.

Claude plugin

A one-click "shortcut"

A handy Claude-only bundle that plugs into that socket in one click. The features live in the socket (MCP); the plugin is just a shortcut for Claude.
