MCP server that gives AI coding tools the same CSS visibility you have in DevTools — rendered class names, full cascade, what's winning and why.
MCP server that gives AI coding tools the same CSS visibility you have in DevTools — rendered class names, full cascade, what's winning and why.
A debugging primitive, not a testing tool — no test runner, no pass/fail. Before your AI writes CSS, let it see what's actually in the browser — the real rendered class names, the full cascade of rules, what's winning and why. Same data a human gets from DevTools. Zero manual copy-paste. When something doesn't work, the tool explains why and points toward the likely cause.
