The Computer Use Agent That Doesn’t Hijack Your Mac.

Give Claude Code direct MCP superpowers into native desktop apps — tapping Meta AI for live Instagram trends and Google Gemini for continuous video QA — running 100% invisibly in the background while you keep typing code.

Add to Claude Code via MCP Clone Open Source Engine

0.00px Physical Mouse Drift

0ms Keyboard Focus Theft

0 Mission Control Swooshes

~500 Lines of Clean Python

0 Focus Theft

If you cannot use your computer, it is not automation.

Current computer use agents turn your workstation into a frozen kiosk. GhostCUA routes directly through the Darwin Accessibility tree and Carbon AppleEvents.

Traditional Screen-Hijacking CUA

Anthropic CUA, trycua, and traditional visual agents

Fires 60fps ScreenCaptureKit loops eating battery

Steals hardware mouse pointer and jerks coordinates

WindowServer triggers Mission Control Space swoosh

Target window flashes to front; IDE typing lost

Result: Developer cannot touch their laptop until the agent finishes.

GhostCUA Background Engine

Native PyObjC, Carbon AppleEvents, and FastMCP

Direct AppleEvent aevt/odoc with kAENeverInteract

DFS Accessibility tree traversal targets PID directly

In-place AXUIElement text injection with verified clearance

Lossless pasteboard restoration preserves user clipboard

Result: 0px cursor movement. 0ms focus loss. You keep coding undisturbed.

Built For Your Coding Agent Workflow

GhostCUA ships with native Model Context Protocol (MCP) servers. Configure it once, and Claude Code, Cursor, Zed, or Antigravity can call desktop apps as first-class tools.
