If you're testing iOS apps in the simulator or automating macOS UI interactions, this gives Claude direct access to xcrun simctl commands plus a Swift native bridge for accessibility APIs. It exposes tools for launching simulators, installing apps, taking screenshots, and running UI automation actions like tap, type, and element inspection. The Swift layer handles the AppKit and CoreGraphics calls that Node can't touch directly. Requires macOS 14+, Xcode tooling, and accessibility permissions granted to whatever process launches the server, not the target app. The installer script handles registration across Claude Code, Codex, Gemini, and other MCP clients with npx or local build options.
