The inspiration? Debugging a friend's WordPress + Elementor site. After staring at the GUI generated stylesh*t several times, I decided I'd rather build a tool than read another line of it myself.
I'm also really puzzled how chrome-devtools-mcp got so popular without providing such basic DevTools functionality after months of release. YouTubers and bloggers keep praising it as "DevTools for agents," but it's mostly just Puppeteer automation — agents are left blind with only the a11y tree to work with.
Which raises a question: should I add automation features too? Or keep this focused on the inspection side? Would love suggestions!
