It provides a set of tools for performing browser operations such as tab management, DOM manipulation, CSS injection, and screenshot capture.

How to use Chrome Extension MCP Server (Go Version)?

常见问题

What dependencies are required?

You need a Go runtime to run the server from source or a prebuilt binary, plus the Chrome browser with the companion Chrome extension installed.

How do I configure the server for Claude?

Add a MCP server entry to your `claude_desktop_config.json` with the command pointing to the binary and set the `CHROME_EXTENSION_ID` environment variable to the installed extension’s ID.

What transport does the server use?

The server uses a WebSocket to communicate with the Chrome extension, and implements the Model Context Protocol (MCP) to expose tools to Claude.

How do I install the Chrome extension?

You can either build the Docker image and extract the extension directory, or manually navigate to the `extension/` folder and load it as an unpacked extension in Chrome’s developer mode at `chrome://extensions/`.
