Reported experience

  1. What they did

    The built-in computer-use MCP server is enabled through /mcp, and macOS Accessibility and Screen Recording permissions are granted. The developer approves each app per session. Claude then runs xcodebuild, launches the app, clicks through windows, resizes them to reproduce layout problems, takes screenshots, and reads the code to suggest a fix.

  2. How it went

    The article describes the workflow but gives no measured results. It is a research preview, so behavior may change between versions.

  3. Worth knowing

    It needs a Pro or Max plan, Claude Code v2.1.85 or later, and macOS in an interactive session. It runs on your real desktop, so check manually anything where a wrong click could cause side effects.

Example prompts

Try with Claude Code
Compile and launch my macOS app in [project path]. Click through each screen, including [key screens or flows], and look for layout bugs like clipped text, overlapping views, or misaligned controls. Finish with a list of each bug, the screen it was on, and a suggested fix; don't change any code until I approve.
