n8n MCP is an 🏷️#open-source 📝Model Context Protocol (MCP) server that gives AI coding assistants structured access to 📝n8n's node library so they can build and manage workflows. Released under the MIT License and maintained by Romuald Czlonkowski, it connects assistants such as Claude Code, Cursor, and Windsurf to n8n's node documentation, properties, and operations.
The server indexes n8n's full catalog of core and community nodes, along with AI-capable tool variants and workflow templates, and exposes more than two dozen tools an assistant can call to search nodes, validate configurations, and — when API credentials are supplied — create and update workflows on a running n8n instance. It is distinct from n8n's own native MCP nodes, the MCP Server Trigger and MCP Client Tool: rather than exposing existing workflows as tools for an agent to call, n8n MCP turns the assistant itself into an n8n workflow builder. It is among the most widely used community MCP servers for n8n, alongside alternatives such as leonardsellem/n8n-mcp-server.
Key Features
- Node knowledge base — Indexes n8n's full library of core and community nodes with documentation, properties, and operations for an assistant to query.
- Configuration validation — Checks node settings and workflow structure so errors surface before a workflow is deployed.
- Direct deployment — Creates and updates workflows on a connected n8n instance when API credentials are provided.
- Multi-assistant support — Works with Claude Code, Cursor, Windsurf, VS Code, and other MCP-capable clients.
