What is it?

n8n-MCP is a Model Context Protocol server that gives AI assistants structured knowledge of n8n's workflow automation nodes. It covers 3,135 nodes (840 core and 2,295 community), including their properties, available operations, documentation, and AI tool variants, so an assistant can look up the right configuration instead of guessing parameter names.

Beyond node lookup, the server can validate node configs and whole workflows, search a library of 2,352 workflow templates, and surface real-world configuration examples. When an n8n instance is connected through an API key, it can also create, update, test and delete workflows, manage executions, folders, credentials and data tables.

It works with MCP clients such as Claude Desktop, Claude Code, Cursor, Windsurf and VS Code, and can be run through npx, Docker, Railway or a remote HTTP deployment. A read-only mode lets administrators disable write and destructive tools.

Key features

  • 01Searches and inspects 3,135 n8n nodes, including property schemas and operations.
  • 02Validates individual node configurations and complete workflows before deployment.
  • 03Searches 2,352 workflow templates by keyword, node type, task or metadata.
  • 04Creates, updates, tests and deletes workflows on a connected n8n instance.
  • 05Supports a read-only deployment mode that disables write tools.

Use cases

  • Letting Claude or Cursor draft n8n workflows with correct node parameters.
  • Validating AI-generated workflow JSON before importing it into n8n.
  • Auditing an n8n instance for security issues with an AI assistant.
  • Running a governed, read-only AI assistant against production n8n workflows.

Quick start

  1. 1

    Sign up at dashboard.n8n-mcp.com and get your API key

  2. 2

    Connect your MCP client (such as Claude Code, Cursor or VS Code) using the setup guide for it

Things to know

  • The hosted free tier is limited to 100 tool calls per day.
  • Deploying and managing workflows on your own n8n instance requires configuring an n8n API key.
