Bridges Claude to your actual Chrome browser instead of spinning up headless instances. Installs as both an MCP server and Chrome extension that communicate over WebSocket. Exposes 18 tools covering snapshots (accessibility tree with element refs), screenshots, clicks, typing, scrolling, tab management, console logs, and network requests. The key advantage is it operates on your real browser sessions, so corporate SSO, existing cookies, and authenticated states just work. Ships with agent rules that teach the snapshot-first workflow. Useful when you need Claude to verify UI changes, debug live pages, or interact with apps that require real auth without Playwright setup overhead.
