概要

What is Chrome Extension MCP Server (Go Version)?

A Go implementation of the Model Context Protocol (MCP) server for the Chrome Extension API, enabling Claude to interact with Chrome browser extensions via a WebSocket bridge.

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/`.
