Antigravity Link
Remote-control Antigravity IDE sessions from your phone or another agent via MCP and the local bridge.
Overview
Antigravity Link is a Build-phase MCP server that connects agents and a mobile companion to local Antigravity IDE sessions through an authenticated bridge.
What is this MCP server?
- MCP server plus OpenAPI-backed mobile companion for Antigravity IDE sessions
- npm package antigravity-link-extension (v1.0.13) with stdio transport
- Requires AG_BRIDGE_URL and AG_BRIDGE_TOKEN from the Antigravity Link QR URL
- GitHub: cafeTechne/antigravity-link-extension
- Published server version 1.0.13
- Transport: stdio
- Two required env vars: AG_BRIDGE_URL and AG_BRIDGE_TOKEN
Community signal: 187 GitHub stars.
What problem does it solve?
Long Antigravity agent sessions chain you to your desk because there is no secure, MCP-native way to interact with the IDE from elsewhere.
Who is it for?
Solo builders using Antigravity who want mobile session control and MCP hooks while actively coding with agents.
Skip if: Developers not on Antigravity IDE, teams needing production monitoring, or anyone unwilling to run and secure a local bridge.
What do I get? / Deliverables
With the bridge URL and QR token configured, you can control and observe Antigravity IDE sessions from mobile or MCP tools without exposing the IDE blindly to the internet.
- MCP tools wired to the local Antigravity Link bridge
- Authenticated mobile/OpenAPI path to IDE session control
- Repeatable env-based setup for agent clients

Journey fit
Session control and IDE bridging matter while you are actively building and pairing with an agent in Antigravity. It extends how you operate the agent IDE (mobile companion, bridge token), which is agent-tooling rather than app feature code.
How it compares
IDE session remote control via MCP, not a cloud deploy tool or code-review skill.
Common Questions / FAQ
Who is Antigravity Link for?
Antigravity IDE users who want a mobile companion and MCP integration to manage agent sessions from outside the desktop editor.
When should I use Antigravity Link?
Use it during Build when you run lengthy agent tasks in Antigravity and need to approve, check, or steer sessions from your phone or via another MCP client.
How do I add Antigravity Link to my agent?
Install antigravity-link-extension, start the local Antigravity Link bridge, copy AG_BRIDGE_TOKEN from the QR URL, set AG_BRIDGE_URL and the token in env, and register the stdio MCP server in your agent config.
