Frontend Design Loop MCP

Frontend Design Loop MCP is an MCP (Model Context Protocol) server focused on enhancing the visual quality of functional web pages through screenshot-grounded iterative refinement. It allows coding agents and AI assistants to point the server at a repository and design goal, then automates previewing, screenshot capture, patch generation, and proof artifact creation, all while maintaining human-judgable before/after results. Integrations include popular MCP clients (Claude, Cursor, Windsurf, and more), and it supports setup for a variety of agent systems. It is ideal for developers, AI agent builders, and teams seeking to automate not just web coding but end-to-end design improvement and validation workflows.
