README

BrowserTools MCP

Give your AI coding agent eyes on the browser. BrowserTools MCP streams console output, network activity, screenshots and Lighthouse audits from your real Chrome session — the one already logged into your app — to any MCP-compatible client: Cursor, Claude Code, Windsurf, Cline, Zed, Gemini CLI, and others.

Version 2.0 is a rewrite. One process instead of three, no unauthenticated local server, credentials scrubbed before they leave the browser, and a real test suite. If you are coming from 1.x, read MIGRATION.md — and upgrade, because 1.2.x has a critical vulnerability. See SECURITY.md.

Why this instead of a CDP-based server

Tools like Chrome DevTools MCP and Playwright MCP drive a fresh, automated browser. That is the right choice for writing tests. It is the wrong choice for debugging the app you are actually looking at, because since Chrome 136 the browser refuses remote debugging on your default profile — the one holding your logins. So you end up recreating your auth state in a throwaway profile before you can debug anything.

BrowserTools attaches to the session you are already in, through a DevTools extension. You stay logged in, on the page you were already on, and your agent reads what you see. It also reports Lighthouse-grade performance, accessibility and SEO data, which the automation-first servers do not.

Install

Two pieces: an MCP server (one command) and a Chrome extension.

1. Point your MCP client at the server

{
  "mcpServers": {
    "browser-tools": {
      "command": "npx",
      "args": ["-y", "@agentdeskai/browser-tools-mcp@latest"]
    }
  }
}

On Windows, if your client cannot find npx, use "command": "cmd" with "args": ["/c", "npx", "-y", "@agentdeskai/browser-tools-mcp@latest"].

Requires Node 22.19 or newer. Check with node --version; if you use nvm or asdf, make sure your editor inherits the same version.

2. Load the Chrome extension

Download or clone this repository.
Open chrome://extensions and turn on Developer mode.
Choose Load unpacked and select the chrome-extension directory.

That is the whole setup. There is no second server to start — the MCP server runs the connector itself.

3. Use it

Open Chrome DevTools (F12) on the page you want to inspect. Capture begins as soon as DevTools is open; the BrowserTools panel is only for settings and status. Then ask your agent something like "check the console for errors" or "run an accessibility audit on this page".

Not working? Run npx @agentdeskai/browser-tools-mcp --doctor, which reports exactly which piece is missing.

To watch capture happen live — useful when checking a fresh install — start the connector with --verbose:

npx @agentdeskai/browser-tools-server --verbose

· console error tab 42 Uncaught TypeError: total is not a function
· network 500 POST tab 42 https://myapp.local/api/pay (1310ms)

Without it the connector only reports connect and disconnect, so a working setup and a silent one look the same.

Tools

Tool	What it does
`getConsoleLogs`	Console output, filterable by keyword with paging
`getConsoleErrors`	Error-level output and uncaught exceptions
`getNetworkLogs`	XHR/fetch requests with status, timing and bodies
`getNetworkErrors`	Only failed and 4xx/5xx requests
`getSelectedElement`	The element selected in the Elements panel
`getPageInfo`	Which page the browser is currently on
`getConnectionStatus`	Whether the extension is connected, and capture counts
`listBrowserTabs`	Every tab with DevTools open, and the id to address it by
`takeScreenshot`	Screenshot returned as an image, plus its file path
`refreshBrowser`	Reloads the inspected tab
`getBrowserStorage`	localStorage, sessionStorage and cookies (values gated)
`wipeLogs`	Clears captured telemetry before
