Browser Monitoring MCP Server

This MCP (Model Context Protocol) server uses Playwright to open a browser, monitor console logs, and track network requests. It exposes these capabilities as tools that can be used by MCP clients.

Features

• Open a browser at a specified URL
• Monitor and retrieve console logs
• Track and retrieve network requests
• Close the browser when done

Requirements

• Python 3.8+
• Playwright
• Model Context Protocol (MCP) Python SDK

Installation in claude

Edit the file: ~/Library/Application\ Support/Claude/claude_desktop_config.json

Add this:

"playwright": {
   "command": "/Users/christophersettles/.local/bin/uv",
   "args": [
      "--directory",
      "/ABSOLUTE/PATH/TO/playwrightdebugger/",
      "run",
      "mcp_playwright.py"
   ]
}

(Replace /ABSOLUTE/PATH/TO/playwrightdebugger/ with the absolute path to the directory where you cloned the repository)

Commands

Open localhost:3000/dashboard and look at console logs and network requests

Close the browser

How It Works

The server uses Playwright's event listeners to capture console messages and network activity. When a client requests this information, the server returns it in a structured format that can be used by the LLM.
