Overview

Chrome Debug MCP Server is a Model Context Protocol (MCP) server designed to control Chrome with debugging capabilities, allowing users to debug webpages using large language models (LLMs).

To use the server, clone the repository, install dependencies, and configure it in the Roo Code extension. You can then launch Chrome with custom profiles, inject userscripts, and interact with web pages programmatically.

Launch Chrome with custom configurations and user profiles. - Automate page interactions like clicking, typing, and taking screenshots. - Remote debugging via Chrome DevTools Protocol (CDP). - Userscript injection with Greasemonkey-style API support. - Extension integration and management.

Debugging web applications using LLMs.
Automating repetitive tasks in web browsers.
