    A local MCP server that enables AI coding assistants to drive the real, already-logged-in Chrome browser — navigating pages, clicking, typing, reading content, taking screenshots, and inspecting tabs, cookies, and network traffic through natural language. It works as a Chrome extension, so no remote-debugging port needs to be opened and pages the user is already signed into are fully usable.
