This gives Claude direct access to Chrome DevTools Protocol for browser automation and debugging. It handles the full workflow: navigate to pages, wait for elements, take snapshots with unique element IDs, then interact with those elements. The snapshot approach is clever because it gives you the accessibility tree with UIDs you can reference for clicks and fills. Supports the usual suspects like screenshots, script evaluation, network inspection, and performance tracing. There's also extension testing support if you need to verify popups or content scripts. If you're building scrapers, running visual tests, or debugging web apps programmatically, this beats writing your own CDP wrapper. Just note it needs full MCP mode, not slim.
