Overview
What is UIMax MCP?
UIMax MCP is a Model Context Protocol server that turns Claude Code into a frontend expert. It automatically reviews and fixes web UI by capturing screenshots, running accessibility audits (axe-core), Google Lighthouse, Core Web Vitals, SEO checks, AST-based code analysis, and generating letter-grade Report Cards — then implementing the fixes directly in your code.
How to use UIMax MCP?
Install in one command: claude mcp add uimax -- npx -y uimax-mcp. Then in any Claude Code conversation, say “Review the UI at http://localhost:3000, source code is in ./src” and UIMax runs the full pipeline automatically. You can also install globally with npm install -g uimax-mcp.
