Claude Code Setup

Connect n8n-MCP to Claude Code CLI for enhanced n8n workflow development from the command line.

Quick Setup via CLI

Basic configuration (documentation tools only):

claude mcp add n8n-mcp \
  -e MCP_MODE=stdio \
  -e LOG_LEVEL=error \
  -e DISABLE_CONSOLE_OUTPUT=true \
  -- npx n8n-mcp

Full configuration (with n8n management tools):

claude mcp add n8n-mcp \
  -e MCP_MODE=stdio \
  -e LOG_LEVEL=error \
  -e DISABLE_CONSOLE_OUTPUT=true \
  -e N8N_API_URL=https://your-n8n-instance.com \
  -e N8N_API_KEY=your-api-key \
  -- npx n8n-mcp

Make sure to replace https://your-n8n-instance.com with your actual n8n URL and your-api-key with your n8n API key.

Alternative Setup Methods

Option 1: Import from Claude Desktop

If you already have n8n-MCP configured in Claude Desktop:

claude mcp add-from-claude-desktop

Option 2: Project Configuration

For team sharing, add to .mcp.json in your project root:

{
  "mcpServers": {
    "n8n-mcp": {
      "command": "npx",
      "args": ["n8n-mcp"],
      "env": {
        "MCP_MODE": "stdio",
        "LOG_LEVEL": "error",
        "DISABLE_CONSOLE_OUTPUT": "true",
        "N8N_API_URL": "https://your-n8n-instance.com",
        "N8N_API_KEY": "your-api-key"
      }
    }
  }
}

Then use with scope flag:

claude mcp add n8n-mcp --scope project

Managing Your MCP Server

Check server status:

claude mcp list
claude mcp get n8n-mcp

During a conversation, use the /mcp command to see server status and available tools.

Remove the server:

claude mcp remove n8n-mcp

Project Instructions

For optimal results, create a CLAUDE.md file in your project root with the instructions from the main README's Claude Project Setup section.

Tips

If you're running n8n locally, use http://localhost:5678 as the N8N_API_URL
The n8n API credentials are optional - without them, you'll have documentation and validation tools only
With API credentials, you'll get full workflow management capabilities
Use --scope local (default) to keep your API credentials private
Use --scope project to share configuration with your team (put credentials in environment variables)
Claude Code will automatically start the MCP server when you begin a conversation
