How to Set Up and Use N8N2MCP
N8N2MCP is a bridge that converts your existing n8n workflows and agents into fully callable MCP (Model Context Protocol) servers, making them accessible from AI assistants like Claude, Cursor, and other MCP-compatible clients. Instead of rebuilding automation logic, you point N8N2MCP at your n8n instance and it dynamically exposes each workflow as an AI-callable function. This lets you reuse hundreds of pre-built n8n integrations—email, CRMs, databases, webhooks—as tools for your AI agent.
Prerequisites
- Docker and Docker Compose installed (recommended) or Python 3.9+ for manual setup
- A running n8n instance with workflows you want to expose
- n8n API key and base URL for your n8n instance
- A Supabase project (URL, anon key, and service role key)
- An MCP-compatible client such as Claude Desktop or Cursor
Clone the N8N2MCP repository
Clone the repository from GitHub to get the Docker Compose setup and configuration files.
git clone https://github.com/Super-Chain/N8N2MCP.git
cd N8N2MCPConfigure environment variables
Copy the example env file and fill in your credentials for Supabase, n8n, and the MCP router.
cp env.example .envSet required variables in .env
Configure the required credentials. N8N_BASE_URL must use https://, and N8N_BUILDER_URL must use http://. FLASK_HOST/PORT control the marketplace server and MCP_HOST/PORT control the MCP router.

FLASK_HOST=0.0.0.0
FLASK_PORT=5000
MCP_HOST=0.0.0.0
MCP_PORT=6545Start with Docker Compose
Launch all services with Docker Compose. This starts the marketplace server and MCP router.
docker-compose up -dVerify the MCP router is running
Test that the MCP router is running and can list available workflow endpoints.
curl http://localhost:6545/listConfigure your MCP client
Add the N8N2MCP server to your MCP client using the generated endpoint URL. Each workflow is accessible at /mcp/{workflow_id}/{api_key}.
N8N2MCP Examples
Client configuration
Add the N8N2MCP server to your claude_desktop_config.json. The server exposes workflows via HTTP, so you connect to the running router endpoint.

}Prompts to try
Once your n8n workflows are connected as MCP tools, use these prompts with Claude to trigger automation.
- "Run my 'Send Welcome Email' workflow for new user [email protected]"
- "Trigger the CRM sync workflow to pull latest contacts from HubSpot"
- "Execute the Slack notification workflow with message: 'Deploy complete'"
- "List all available n8n workflows I can run"
- "Run the data export workflow and tell me how many records were processed"Troubleshooting N8N2MCP
Docker Compose starts but /list returns empty or connection refused
Check that N8N_BASE_URL is accessible from inside Docker and uses https://. Verify N8N_BUILDER_URL uses http:// (not https://). Run 'docker-compose logs mcp-router' to see connection errors.
Supabase authentication errors on startup
Make sure SUPABASE_SERVICE_KEY is the service role key (not the anon key) for admin operations. The anon key goes in SUPABASE_KEY. Both are found in your Supabase project Settings > API.
n8n workflows not appearing as MCP tools
The n8n API key (X_N8N_API_KEY) must have permission to list and execute workflows. Generate a new API key in n8n under Settings > n8n API and ensure your workflows are active (not draft).
