      "args": [
        "mcp-remote",
        "https://mcp.datagen.dev/mcp"
      ]
    }
  }
}

Restart

Close and reopen Claude Desktop to load the new MCP connection.
Requires Node.js/npm installed on your system for the npx command.

​
Method 4: Claude Code CLI

claude mcp list

​
Method 5: Cursor IDE

  3. In the Command field, enter: 
    npx mcp-remote https://mcp.datagen.dev/mcp

​
Verify Your Connection

Test your connection in any Claude interface:

Test Connection

Ask Claude: “List all available DataGen tools”You should see tools like executeCode, searchTools, addRemoteMcpServer, and createCustomTool.

​
Troubleshooting

  1. Verify your JSON configuration is valid (use a JSON validator)
  2. Ensure you restarted Claude Desktop after adding the config
  3. Check that npx is installed and accessible in your terminal
  4. Try running datagen mcp again to reconfigure
  1. Check your internet connection
  2. Verify the URL: https://mcp.datagen.dev/mcp
  3. If behind a corporate firewall, contact your IT team about MCP access
  1. Verify your API key is correct: datagen login
  2. Some tools require OAuth authentication — use addRemoteMcpServer to connect external services
  1. Ensure you have curl installed: which curl
  2. Try running with sudo: sudo sh -c "$(curl -fsSL https://cli.datagen.dev/install.sh)"
  3. Manual install: Download from GitHub releases
