Cupertino
Local Apple Documentation crawler and MCP server written in Swift. Crawls, indexes, and serves 302,000+ Apple developer documentation pages across 307 frameworks via MCP. Provides sub-100ms full-text search using SQLite FTS5 with BM25 ranking, plus access to Swift Evolution proposals, sample code, and Human Interface Guidelines.
Best When
You develop for Apple platforms and want deterministic, offline, hallucination-free documentation access from AI assistants. The pre-built database downloads make setup take about 30 seconds.
Avoid When
You don't do Apple development, or you're on Linux/Windows. Also avoid if you have very limited disk space (needs ~2.4 GB).
Use Cases
- • Offline Apple documentation search for AI coding assistants
- • Querying SwiftUI/UIKit/AppKit docs from Claude or Cursor without hallucination
- • Searching Apple sample code projects and reading source files
- • Looking up Swift Evolution proposals during development
- • Browsing Human Interface Guidelines by platform
Not For
- • Non-Apple development (Android, web, etc.)
- • Linux or Windows users (requires macOS 15+)
- • Users needing real-time documentation updates (crawl is periodic)
