Ui Annotator Mcp

UI Annotator MCP is an open-source Model Context Protocol (MCP) server/integration that bridges the gap between human and AI communication for web UI iteration, design, and automation. It works as a local reverse proxy that annotates every visible web element with human-readable labels, enabling users (and AI assistants) to instantly identify, reference, and manipulate UI components without ambiguity. Designed for product teams, QA, designers, junior devs, and anyone collaborating with AI on software UI changes, it removes the need for browser extensions or code modifications and is framework-agnostic.
