NexusWindows for Antigravity

Windows computer use for Antigravity, in the background. An MCP server (nexus-windows-antigravity) that lets Google Antigravity (Gemini) see and operate Windows desktop applications while the user keeps their mouse, keyboard and foreground window. Built for a fast model: one look, then one batch of steps with label targets, and every reply says what to do next.

Version 3.0.2 · Windows 10/11 · Python 3.11+ · MIT licence

Part of the Nexus family: NexusWindows (Claude · Codex · Antigravity), NexusBrowser (repo), NexusAndroid (repo). Project page: julienpiron.fr/nexuswindows.

Why

Screenshot-and-click computer use moves the real cursor and brings windows to the front, so the person at the PC has to stop working while the agent acts. Most Windows applications can be driven without that: native controls accept window messages and modern frameworks expose UI Automation. This server acts in the background first, reads the effect back, and only falls back to the real mouse or keyboard when the step allows it (foreground=True).

NexusWindows family

Three MCP servers, one per agent, built separately because each model needs its tools shaped for it, with the same promise: the user keeps their mouse, keyboard and foreground window, and every action is read back.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
