What is n8n Workflow Builder MCP Server?

An AI-powered MCP server that lets you build, manage, and monitor n8n workflows through natural language using Claude AI and Cursor IDE. It transforms workflow automation by enabling conversational creation and management of complex n8n workflows, eliminating manual JSON editing and UI navigation.

How to use n8n Workflow Builder MCP Server?

Install globally via npm (npm install -g @kernel.salacoste/n8n-workflow-builder). Configure with a .config.json (multi‑instance) or a .env file (single instance). Add the server to your Claude Desktop configuration (claude_desktop_config.json) or Cursor IDE configuration (.cursor/mcp.json). Restart the client and describe workflows in plain English.

Key features of n8n Workflow Builder MCP Server

  • AI-powered workflow creation from natural language descriptions
  • Multi-instance management (dev, staging, production) from one server
  • 17 comprehensive tools covering workflows, executions, tags, and credentials
  • Natural language interface – no JSON editing required
  • Secure by design with API key encryption and credential protection
  • 38+ documentation pages with guides, tutorials, and API reference

Use cases of n8n Workflow Builder MCP Server

  • Build and test workflows locally, then promote through staging to production
  • Monitor execution status and debug failed workflows across environments
  • Export workflows from one n8n instance and import to another with automatic adaptation
  • Generate workflow documentation and learn n8n patterns through AI guidance

FAQ from n8n Workflow Builder MCP Server

What does the MCP server do?

It enables Claude AI and Cursor IDE to interact with n8n via the Model Context Protocol, allowing you to create, manage, and monitor workflows using natural language commands.

What are the prerequisites?

You need Node.js v14+ (v18+ recommended), npm v7+, a running n8n instance with API access (tested with n8n v1.82.3+), and either Claude Desktop or Cursor IDE.

How does multi-instance management work?

A single MCP server can manage multiple n8n environments (e.g., production, staging, development) by reading a .config.json file that defines each environment’s host and API key. The server routes requests to the correct instance based on context.

What tools are included in the MCP server?

Eight workflow tools (create, update, delete, activate, execute, etc.), four execution tools (monitor, retry, delete), five tag management tools, and six credential tools (schema retrieval, creation, deletion – note that list/get/update credential are blocked by the n8n API and only provide guidance).

Is the MCP server secure?

Yes. It features built-in credential protection, API key encryption, secure multi-instance configuration, and never exposes sensitive data in logs.
