UI Debugger MCP
UI Debugger MCP: the AI that wrote your app can also test it
Your coding agent hands over a story. A small fast agent drives the browser, desktop or Android app and reports what broke, with evidence.
What it does
Goals in, findings out
The coding agent stays high-level and never clicks. It gets pass or fail, what broke and the evidence, fixes the code and asks again.
Three targets
Web over the Chrome DevTools Protocol, desktop over X11 or Wayland, and Android over ADB, behind one adapter contract.
Reviewable runs
Every run keeps its screenshots and stitches them into a short captioned replay video that can go on the pull request.

Want to help?
Bug fixes, bug reports and suggestions are welcome. Dependency, CI and release changes, big rewrites and unasked features are not. The page says why.
How outside contributions work
Ship more. Maintain less.
We expect software to be written faster than any team can review it. Bring your repos, your boxes and your keys. We bring the org that keeps up.
