How to Set Up and Use Antigravity Link Mobile
Antigravity Link is an MCP server and mobile companion for Google's Antigravity IDE that captures live snapshots of the Antigravity chat UI via Chrome DevTools Protocol and serves them to a mobile web client over a locally-hosted HTTPS bridge. It exposes 9 MCP tools — including get_snapshot, send_message, stop_generation, switch_instance, and click_element — plus a full OpenAPI-compatible REST interface secured by a bearer token. Developers use it to remotely monitor and drive long-running AI coding sessions from a phone without being tied to their workstation.
Prerequisites
- Google Antigravity IDE installed
- Node.js 16 or higher installed
- Antigravity IDE launched with '--remote-debugging-port=9000' flag
- An MCP client such as Claude Desktop
- Mobile device on the same local network
Launch Antigravity IDE with remote debugging
The Chrome DevTools Protocol connection requires Antigravity IDE to be started with the remote debugging port flag enabled.
antigravity-ide --remote-debugging-port=9000Install and start the Antigravity Link server
Run the server via npx. It starts a local HTTPS bridge server on port 3000 by default and prints a QR code with the mobile URL and bearer token.
npx -y antigravity-link-extensionNote your bearer token
When the server starts, it displays a token (also encoded in the QR code). Copy this token — you will need it in the MCP client config as AG_BRIDGE_TOKEN and for direct API calls.
Configure Claude Desktop
Add the server to claude_desktop_config.json. Set AG_BRIDGE_URL to the local HTTPS address and AG_BRIDGE_TOKEN to the token from the previous step.

}
}
}Connect from your mobile device
Scan the QR code with your phone's camera. Your mobile browser will open the Selene web client connected to your live Antigravity session.

Example MCP-based prompts and direct API calls for controlling Antigravity IDE remotely.
- "Get a snapshot of the current Antigravity IDE session"
- "Send 'Refactor the authentication module for readability' to Antigravity"
- "Stop the current AI generation in my Antigravity window"
- "List all open Antigravity IDE instances"
- "Switch to Antigravity window instance 2"
- "Click the element with selector '#run-button' in Antigravity"Troubleshooting Antigravity Link Mobile
Bridge server cannot reach Antigravity via CDP
Confirm Antigravity IDE is running with '--remote-debugging-port=9000'. Test with 'curl http://localhost:9000/json/version'. If the port is in use by another process, kill it or choose a different port and update the launch flag accordingly.
Mobile browser shows certificate error when scanning QR code
The HTTPS server uses a self-signed certificate. On your mobile browser, navigate to the URL shown in the QR code, tap 'Advanced', and accept the security exception. Alternatively set antigravityLink.useHttps to false if microphone access is not needed.
Bearer token authentication fails with 401
Copy the token exactly as displayed when the server started — it is case-sensitive and may contain special characters. Set it as AG_BRIDGE_TOKEN in your MCP config or pass it in the Authorization header as 'Bearer <token>' for direct API calls.
