What is the Ui MCP Server?

Annotates any web page with hover labels for AI assistants — zero extensions, any browser

What it actually does

The only tool that puts visible labels on every web element. Hover any element, see its name. Tell your AI assistant "make the sidebar wider" — it knows exactly which element you mean. No screenshots, no CSS selectors, no miscommunication.
