Frontend Design Loop MCP

Frontend Design Loop MCP is a Model Context Protocol (MCP) server/integration that enhances existing functional web pages by iteratively improving their frontend design through screenshot-grounded workflows and artifact proofing. Used after coding agents have made a page functional but it still lacks visual polish or premium feel, this MCP coordinates design goals, manages previews, captures screenshots, runs deterministic checks, and returns improved design patches with proof artifacts such as before/after screenshots and execution logs. It is intended for developers and AI agents who want to automate and upgrade frontend visual design in a structured manner.
