How to Install n8n MCP on Ubuntu 24.04

n8n MCP is a Model Context Protocol (MCP) server that enables AI agents — including Claude Desktop, Claude Code, Windsurf, and Cursor — to build, read, update, and execute n8n workflows programmatically. With 22k+ GitHub stars, it bridges the gap between AI assistants and n8n's powerful workflow automation engine. Instead of manually dragging nodes in n8n, you describe what you want and the AI agent creates and manages the workflow for you.
