Better Design: MCP Server for Design Systems and UI Reviews in Coding Agents

Repositorymarvkr/better-designTool

Better Design is an open-source MCP server and shadcn/ui registry that provides AI coding tools like Claude Code, Cursor, and GitHub Copilot with design systems, design tokens, and WCAG review rules.

Key points

  1. Provides an MCP server delivering curated design systems, semantic CSS tokens, and component code to coding agents.
  2. Includes 31 brand-grade themes inspired by products like Linear, Stripe, Vercel, Apple, Notion, Supabase, and Figma.
  3. Feeds explicit UI principles covering typography, spacing, hierarchy, depth, and motion into the agent's context.
  4. Features a 'get-review-rules' mechanism for automated checking against WCAG accessibility rules, focus states, and contrast.
  5. Supports any MCP-compatible client including Claude Code, Cursor, VS Code / GitHub Copilot, and Claude Desktop.

Why it matters

Coding agents frequently generate generic, inconsistent interfaces lacking proper design coherence and accessibility. By connecting design tokens, component registries, and review rules via the Model Context Protocol, Better Design allows engineering teams to scaffold polished and compliant UI code directly from AI prompts.

Analysis

Better Design addresses the common issue of generic 'AI-looking UI' by supplying real implementation tokens and structured guardrails. Built on TypeScript, Tailwind CSS, and shadcn/ui conventions, it targets frontend developers and product teams using AI coding assistants. With 361 stars and 18 forks, the repository represents an early-stage but functional tool that combines prebuilt aesthetic themes with actionable accessibility checks.
