A native macOS browser built on WKWebView that exposes itself as an MCP server over local HTTP. Instead of headless automation or cloud browsers, this gives LLMs control of a real Safari-engine browser window on your Mac. It ships 40+ tools for navigation, DOM manipulation (click, fill, submit), content extraction (read_text, screenshot, accessibility_tree), cookie and storage management, plus network and console capture. Bearer token auth and DNS rebinding protection keep it local-only. Useful when you want agents to interact with pages using your logged-in sessions and cookies, or when you need to see exactly what the LLM is doing in a real browser UI rather than a headless context.
