Description

This MCP server exposes a set of tools for programmatic interaction with the Chrome browser and installed extensions, enabling agents to query tabs, execute DOM operations, inject CSS, capture screenshots, read cookies, and send messages to extensions. It provides installation instructions (Docker or manual), manifest/permission guidance for the Chrome extension, and example configuration for integrating with Claude Desktop. The package is distributed under the MIT License and uses the Chrome extension APIs (tabs, scripting, cookies, management) to perform actions and stream real-time tab updates.
