MCP server · Audit CLI

Apple HIG lookup and audits for MCP-compatible agents.

HIG Doctor exposes Apple Human Interface Guidelines skills through the Model Context Protocol and ships a CLI that scans native and web UI code for accessibility, layout, color, typography, motion, control, and platform-pattern issues.

The same reference content the tools serve is browsable at /topics, with per-topic Markdown for agents.
