1. Log into your n8n instance
2. Click your user icon in the bottom left
3. Go to Settings
4. Select API
5. Click “Create API Key”
6. Copy your API key (you won’t be able to see it again)

Install the MCP Server

Option 1: Install from npm (Recommended)

npm install -g @illuminaresolutions/n8n-mcp-server

Option 2: Install from Source

1. Clone the repository:

   git clone https://github.com/illuminaresolutions/n8n-mcp-server.git
   cd n8n-mcp-server
   

2. Install dependencies and build:

   npm install
   npm run build
   

3. Start the server in the background:

   nohup npm start > n8n-mcp.log 2>&1 &
   

   To stop the server:

Configuration

Claude Desktop

1. Open your Claude Desktop configuration:

   ~/Library/Application Support/Claude/claude_desktop_config.json
   

2. Add the n8n configuration:

   {
     "mcpServers": {
        "n8n": {
         "command": "n8n-mcp-server",
         "env": {
           "N8N_HOST": "https://your-n8n-instance.com",
           "N8N_API_KEY": "your-api-key-here"
         }
       }
     }
   }
   

Cline (VS Code)

1. Install the server (follow Installation steps above)
2. Open VS Code
3. Open the Cline extension from the left sidebar
4. Click the ‘MCP Servers’ icon at the top of the pane
5. Scroll to bottom and click ‘Configure MCP Servers’
6. Add to the opened settings file:

   {
     "mcpServers": {
       "n8n": {
         "command": "n8n-mcp-server",
         "env": {
           "N8N_HOST": "https://your-n8n-instance.com",
           "N8N_API_KEY": "your-api-key-here"
         }
       }
     }
   }
   

7. Save the file
8. Ensure the MCP toggle is enabled (green) and the status indicator is green

Sage

Coming soon! The n8n MCP server will be available through:

• Smithery.ai marketplace
• Import from Claude Desktop

For now, please use Claude Desktop or Cline.

Validation

After configuration:

1. Restart your LLM application
2. Ask: “List my n8n workflows”
3. You should see your workflows listed

If you get an error:

• Check that your n8n instance is running
• Verify your API key has correct permissions
• Ensure N8N_HOST has no trailing slash
