Common questions

Is Antigravity Link safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: AG_BRIDGE_URL, AG_BRIDGE_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.13) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

You're running an Antigravity session and need to step away from your desk. The AI is mid-generation. You want to monitor it, redirect it, upload a file, or just read what it wrote from your phone, without coming back to your computer.

Antigravity Link makes that possible. Scan a QR code and your phone becomes a live mirror of the active chat: read responses as they stream, send messages, stop generation, upload files, dictate via voice, and switch between multiple Antigravity windows all from a mobile browser, on your local network.

For automation, the extension also exposes a local HTTP API and an MCP server so agents and external tools can drive Antigravity sessions programmatically.

Demo

Screenshots

What you get

Live mirror of the active Antigravity chat — read and interact from your phone.
File upload into the active Antigravity chat.
Voice-to-text input from mobile (HTTPS required for mic permissions).
Stop generation from your phone with a dedicated stop chip.
Active instance switching for multiple Antigravity windows.
Local HTTP API for automation and integrations (see API).
MCP server for AI assistant integration (see MCP server).
Local-only server with token authentication.
Interface available in 16 languages with automatic detection and RTL support.

Installation

Install from the Antigravity extensions marketplace: search Antigravity Link or install directly from Open VSX.

Prerequisites

Antigravity IDE installed and running.
A phone and computer on the same Wi-Fi network.
Antigravity launched with the remote debugging flag. This is required for the extension to discover and connect to your session. See the launch command in Quick start below.

Quick start

Start Antigravity with remote debugging enabled. This is required; sessions launched without this flag are not discoverable by the extension.

Windows:

& "C:\Users\<username>\AppData\Local\Programs\Antigravity IDE\Antigravity IDE.exe" --remote-debugging-port=9000

macOS:

open -a "Antigravity IDE" --args --remote-debugging-port=9000

Linux:

antigravity-ide --remote-debugging-port=9000

Multiple Antigravity sessions are supported, but every window must be launched with this command.

In VS Code, run:

Antigravity Link: Start Server

Then run:

Antigravity Link: Show QR Code

Scan the QR code with your phone. Your mobile UI is ready.

Your phone may warn that the connection is unsafe because the certificate is self-signed. This is expected for local HTTPS. Use your browser's "Advanced" or similar option to proceed (wording differs between Safari/Chrome/Firefox).

Commands

Command	Description
Antigravity Link: Start Server	Starts the local bridge server.
Antigravity Link: Stop Server	Stops the server.
Antigravity Link: Show QR Code	Displays the connection QR code.
Antigravity Link: Select Network Interface	Choose which network interface the QR URL advertises.

Settings

Setting	Default	Description
`antigravityLink.port`	`3000`	Port for the local bridge server.
`antigravityLink.autoStart`	`false`	Start the server on VS Code launch.
`antigravityLink.useHttps`	`true`	Serve over HTTPS for mic access.
`antigravityLink.preferredHost`	`""`	Optional LAN IPv4 to advertise in QR URL (example: `192.168.1.101`).
`antigravityLink.strictWorkbenchOnly`	`true`	Only bind to `workbench.html` CDP targets for stability.
`antigravityLink.includeFallbackTargets`	`false`	Allow jetski/launchpad fallback targets when strict mode is disabled.

For agent builders

If you want to integrate quickly, use this sequence:

Start the extension server and copy the token from the QR URL (?token=...).
Use either MCP tools (mcp-server.mjs) or direct HTTP calls against https://localhost:3000.
Validate control flow with /snapshot, /send, and /stop.

OpenAPI example:

curl -k https://localhost:3000/snapshot \

-H "Authorization: Bearer "

MCP client configuration example:

"antigravity-link": { "command": "node", "args": [" /mcp-server.mjs"], "env": { "AG_BRIDGE_URL": "https://localhost:3000", "AG_BRIDGE_TOKEN": " " } } }

Replace with the path to the installed extension:

Windows: %USERPROFILE%\.antigravity-ide\extensions\cafetechne.antigravity-link-extension-1.0.20
macOS/Linux: ~/.antigravity-ide/extensions/cafetechne.antigravity-link-extension-1.0.20

How it works (high level)

The extension starts a local server (HTTP or HTTPS).
It discovers Antigravity targets via the Chrome DevTools Protocol (CDP).
Your phone connects to the mobile UI and sends upload/command requests.
The extension injects into the selected chat target and saves files to uploads/.

Account safety

Antigravity Link has no known ban cases and is designed to stay that way.

The extension works by connecting to a debug port that Antigravity exposes on your own machine the same Chrome DevTools Protocol used by VS Code's built-in debugger and browser devtools. It reads your local UI and simulates keypresses and clicks, exactly as if you were sitting at your keyboard.

What this means in practice:

All network activity is local. The extension communicates only with: your phone on the LAN via the HTTPS server it starts; Antigravity IDE's Chrome DevTools Protocol port on localhost:9000; and Antigravity's Language Server process on 127.0.0.1 for the stop-generation RPC. No data is sent to Google's servers or any external service beyond what Antigravity itself sends.
Nothing is injected into Antigravity's network traffic. The extension reads your screen and types into your editor it does not intercept or modify API calls.
No Antigravity files are modified. There are no patches, hooks, or binary modifications.
The server runs entirely on your machine. Your prompts, chat history, and files never leave your local network unless you explicitly expose the server externally.
No data is sent to third-party services by this extension.

The source code is MIT-licensed and fully auditable: https://github.com/cafeTechne/antigravity-link-extension

Troubleshooting

No instances found: Make sure every Antigravity window was launched with the --remote-debugging-port command shown above.
Can't connect from mobile: Ensure your phone and computer are on the same network.
Uploads save but don't appear in chat: Switch to the correct Active Instance in the mobile UI.
Stuck on "Initializing…": The server is reachable but the chat surface has not been captured yet. Wait a few seconds for the CDP connection to initialize.

FAQ

Does this work on iOS and Android? Yes. The mobile UI runs in any modern mobile browser Safari on iOS, Chrome on Android, and others all work.

Does this work over cellular or VPN? Not by default: the server is LAN-only. For remote access you would need to expose it through a tunnel such as ngrok, wireguard, etc.. The token authentication and HTTPS remain in place regardless.

Is the self-signed certificate warning safe to accept? Yes. The certificate is generated locally on your machine at server start. The warning appears because it is not issued by a public certificate authority, not because the connection is insecure.

Can I use this for automation? Yes. The local HTTP API and MCP server are designed for exactly this. See the API and MCP server sections.

Internationalization and accessibility

The mobile interface automatically detects your browser's language and renders in:

English · 日本語 · 中文（简体）· 中文（繁體）· 한국어 · Deutsch · Français · Español · Português · Русский · Italiano · Polski · Türkçe · Tiếng Việt · Bahasa Indonesia · العربية

Arabic is rendered right-to-left automatically. Language detection uses navigator.language with no configuration required.

The interface is built with semantic HTML, ARIA roles, aria-live regions for connection status, keyboard navigation, and screen-reader-compatible labels throughout.
