- Holds an n8n access key
Install
- Works in
In your terminal, with SkillFoxx CLI
npx skillfoxx add mcp/n8n-mcpDetects the agents on your machine, shows the access level and pins the version.

What it does
The server gives the agent a bundled database of n8n nodes: properties, operations, docs, example configs and a template library. The agent searches templates and nodes, fetches the parameters it needs and validates individual nodes and whole workflows before running them. If you provide your n8n URL and API key, management tools appear: create, partially update, validate, autofix and test-run workflows. Without a key only reference and validation tools are available.
Who it is for. For people building n8n automations who want an agent to create workflows without node parameter mistakes.
Good fit when
- You need an n8n workflow built from a text description
- The agent gets node parameters wrong and workflows fail at runtime
- You want to find a ready template for a task
Not a fit when
- Your automations are not built in n8n
- You would edit production workflows without a copy or test environment
Example request
Build an n8n workflow that sends a Telegram message on each new webhook submission, validate the config firstMCP
- Transport
- stdio, http
- Authentication
- key is optional
Environment variables
MCP_MODErequired- stdio mode, required for Claude Desktop
N8N_API_URL- Your n8n instance URL for management tools
N8N_API_KEYsecret- n8n API key for creating and editing workflows
N8N_MCP_ACCESS_TOKENsecret- n8n instance-level MCP token for agent management tools
WEBHOOK_SECURITY_MODE- moderate allows calls to n8n on localhost
Limitations
The author explicitly warns against letting the agent edit production workflows without backups and testing. Workflow management needs N8N_API_URL and N8N_API_KEY. The hosted version at dashboard.n8n-mcp.com has a call limit on the free tier; self-hosting needs Node.js or Docker. Running several clients via npx can hit npm cache locks.
How to disable. Run claude mcp remove n8n-mcp or delete the n8n-mcp entry from the client's MCP config. Revoke the API key in n8n settings.
FAQ
Do I need my own n8n?
Not for reference and validation. For the agent to create and run workflows you need API access to your n8n instance.
Why MCP_MODE=stdio?
Without it debug output goes to stdout and Claude Desktop shows JSON parse errors.

README in short
The README describes the n8n node and template knowledge base and warns to be careful with production workflows. The fastest route is the hosted version with a key; self-hosting via npx, Docker, Railway or source is in a separate doc. It includes guides for Claude Code, VS Code, Cursor, Windsurf and Codex, system instructions for Claude projects and a link to the related n8n-skills. MIT licensed.
