Prerequisites

1. Create an Arcade account
2. Get an Arcade API key
3. Create an Arcade MCP Gateway and select the tools you want to use

Set up Cursor

3. Download and open Cursor 
4. Open the command palette and select Open MCP Settings…
5. Choose HTTP
6. Paste the URL of your MCP Gateway
7. Give your MCP server a name, like mcp-arcade
8. Add the API key as the bearer token within the Authorization header, and the email address that you used to sign up for the Arcade account as the Arcade-User-ID header

Cursor will update your settings.json file with the following

      "url": "https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>",
      "headers": {
        "Authorization": "Bearer {arcade_api_key}",
        "Arcade-User-ID": "{arcade_user_id}"
      }
    }
  }
}

Try it out

1. Open the chat pane (typically command-l)
2. Make sure you are in Agent mode
