Antigravity
Run bots on Google Antigravity's command-line agent, and what it can and can't do inside Murage.
Google Antigravity's command-line agent (the agy program) runs Gemini models. Murage runs it as an engine with your own Antigravity sign-in. It's listed as Antigravity.
Antigravity and Gemini are trademarks of their owner. Murage isn't affiliated with Google.
Antigravity works differently from most engines in Murage. It runs each turn in a one-shot mode that has no way to stop and ask you before an action. That shapes what it can do here, so read the limits below before you give it important work.
When to use it
- You already use Antigravity and want a bot on Gemini models.
- The bot works in its own folder, or on a cloud computer or Local VM, where running without per-action approval is acceptable.
Install and sign in
- Open Settings → Engines and find Antigravity.
- If it says Not detected, choose Open install in Terminal. Murage opens Terminal with the right command for your computer.
On macOS and Linux:
curl -fsSL https://antigravity.google/cli/install.sh | bash
On Windows (PowerShell):
irm https://antigravity.google/cli/install.ps1 | iex
- Sign in the way Antigravity's setup guide describes. Choose View setup guide if you need it.
- Back in Murage, choose Check again.
Murage needs Antigravity 1.1.15 or newer.
What works
- Its own tools: Antigravity edits files and runs commands with its own built-in tools.
- Handing off work: in the default setup, an Antigravity bot can hand work to other bots and ask them questions.
- Computers: in the default setup, it can use a cloud computer, a Local VM or your own VPS.
- Pictures you attach reach it as a file it opens with its own file reader.
- Model picking: Antigravity's Gemini models. You can switch the model within a conversation.
Murage adds its computer and teammate tools to Antigravity's own MCP settings file (~/.gemini/config/mcp_config.json) before each turn, using entries it owns. Your own entries in that file are left alone.
Known limits
- No approval cards for its actions. Antigravity can't pause mid-turn to ask you, so no approval cards appear for what it does. Keep it away from work where you'd want to approve each step.
- Not this computer. Because it can't ask first, Murage never lets Antigravity control your own screen.
- No connected apps, built-in browser or phone control.
- No custom MCP servers from Murage, and no Murage memory search tool. Recalled memory is still included with each message.
- No local models. Pick a local model for a bot on Fuigo, pi, OpenCode, Qwen or Hermes instead.
- No Flux Router tiers.
- Voice calls need Flux Router credits or your own voice keys.
Troubleshooting
"Antigravity CLI 1.1.15+ is required. Run agy update." Your Antigravity is too old. Run agy update in a terminal, then choose Check again.
"agy CLI not found" Install Antigravity, restart Murage, or choose Set CLI… and pick the agy program yourself.
"Antigravity can't run local models." Pick that model for a bot on Fuigo, pi, OpenCode, Qwen or Hermes instead.
"Antigravity text generation timed out" The turn took too long. Try again, or break the task into smaller steps.
A command it tried came back as an error Antigravity denies some actions on its own when it isn't in its most permissive mode. Check the tool output in the chat for what was refused.
