an MCP that peeks at any macOS app

An open-source MCP server and Claude Code skill that lets Claude autonomously explore any macOS application, walk through its screens, and produce a rich human-readable audit - UX flaws, full feature scope, even a reverse-PRD pulled out of a competitor app. I built it because I kept wanting that kind of audit on apps I admired (and apps I wanted to outflank) and there was nothing that would just go and do it. (Until Anthropic then made it possible, so I was saved.) Source on GitHub.
