What is the Ui MCP Server?

UI/UX design-audit MCP server: scores a project on 12 dimensions vs WCAG 2.2 + APCA.

What it actually does

Most "design review" tools tell you "improve your contrast." This tool tells you:

  • Real color science. — Contrast is computed with the tool's own WCAG 2.2 and APCA math, not estimated. The fixture's measured ratios (e.g. 1.03:1) are reproducible from lib/color-engine.js
  • Cited WCAG success criteria. — Accessibility findings cite the exact SC: 1.4.3 Contrast (Minimum), 1.4.11 Non-text Contrast, 2.5.8 Target Size, 2.4.7 Focus Visible, 1.1.1 Non-text Content, 3.3.2 Labels or Instructions
  • A regression gate, not a vibe. — 311 tests (run npm test) assert real behavior, including a 12-problem fixture where every finding must carry evidence.file, evidence.line, and a fix. If specificity regresses, the test suite fails
