Overview

What is Codingbaby Browser Mcp?

Codingbaby Browser Mcp is a Model Context Protocol (MCP) tool server that bridges an AI assistant with the Chrome browser via a WebSocket connection to a companion Chrome extension. It enables browser automation control such as navigation, clicking, typing, scrolling, and screenshot capture, using a real Chrome session.

How to use Codingbaby Browser Mcp?

Ensure Node.js 16+, Chrome, and the companion Chrome extension are installed. Install the server from source (npm install then node chrome-server.js) or via npm (npx @sydneyassistent/codingbaby-browser-mcp). The server starts a WebSocket service on port 9876 and communicates with MCP clients via stdio. Register the server in your MCP environment (e.g., .cursor/mcp.json) and restart the environment.

Frequently asked questions

What companion Chrome extension is required?

The server requires a companion Chrome extension that performs actual browser operations. The extension must be installed and enabled in Chrome.

How does the server communicate with the browser?

The server starts a WebSocket server on port 9876. The Chrome extension connects to this WebSocket, and commands are exchanged as JSON messages with unique request IDs for asynchronous responses.

What are the prerequisites for running the server?

Node.js version 16 or later, a Chrome browser, and the companion Chrome extension installed and enabled.

How is Codingbaby Browser Mcp installed?

You can run from source: `npm install` then `node chrome-server.js`, or install the published npm package: `npm install @sydneyassistent/codingbaby-browser-mcp` (or globally with `-g`), then run via `npx`.

What advantages does it have over Puppeteer or Playwright?

It runs as a Chrome extension with higher browser privileges, uses a real user session for anti-bot evasion, mimics real user behavior, maintains login states, and requires only the extension rather than separate browser instances or WebDrivers.
