      "command": "npx",
      "args": ["-y", "@node2flow/n8n-management-mcp"],
      "env": {
        "N8N_URL": "https://your-n8n-instance.com",
        "N8N_API_KEY": "your-n8n-api-key"
      }
    }
  }
}
```

### Cursor / VS Code

Add to MCP settings:

```json
{
  "mcpServers": {
    "n8n": {
      "command": "npx",
      "args": ["-y", "@node2flow/n8n-management-mcp"],
      "env": {
        "N8N_URL": "https://your-n8n-instance.com",
