Chrome DevTools for agents

Chrome DevTools for agents (chrome-devtools-mcp) lets your coding agent (such as Antigravity, Claude, Cursor or Copilot) control and inspect a live Chrome browser. It acts as a Model-Context-Protocol (MCP) server, giving your AI coding assistant access to the full power of Chrome DevTools for reliable automation, in-depth debugging, and performance analysis. A CLI is also provided for use without MCP.

Key features

• Get performance insights: Uses Chrome DevTools to record traces and extract actionable performance insights.
• Advanced browser debugging: Analyze network requests, take screenshots and check browser console messages (with source-mapped stack traces).
• Reliable automation. Uses puppeteer to automate actions in Chrome and automatically wait for action results.

Disclaimers

chrome-devtools-mcp exposes content of the browser instance to the MCP clients allowing them to inspect, debug, and modify any data in the browser or DevTools. Avoid sharing sensitive or personal information that you don't want to share with MCP clients.

chrome-devtools-mcp officially supports Google Chrome and Chrome for Testing only. Other Chromium-based browsers may work, but this is not guaranteed, and you may encounter unexpected behavior. Use at your own discretion. We are committed to providing fixes and support for the latest version of Extended Stable Chrome.

Performance tools may send trace URLs to the Google CrUX API to fetch real-user experience data. This helps provide a holistic performance picture by presenting field data alongside lab data. This data is collected by the Chrome User Experience Report (CrUX). To disable this, run with the --no-performance-crux flag.

Usage statistics

Google collects usage statistics (such as tool invocation success rates, latency, and environment information) to improve the reliability and performance of Chrome DevTools MCP.

Data collection is enabled by default. You can opt-out by passing the --no-usage-statistics flag when starting the server:

"args": ["-y", "chrome-devtools-mcp@latest", "--no-usage-statistics"]

Google handles this data in accordance with the Google Privacy Policy.

Google's collection of usage statistics for Chrome DevTools MCP is independent from the Chrome browser's usage statistics. Opting out of Chrome metrics does not automatically opt you out of this tool, and vice-versa.

Collection is disabled if CHROME_DEVTOOLS_MCP_NO_USAGE_STATISTICS or CI env variables are set.

Update checks

By default, the server periodically checks the npm registry for updates and logs a notification when a newer version is available. You can disable these update checks by setting the CHROME_DEVTOOLS_MCP_NO_UPDATE_CHECKS environment variable.

Requirements

• Node.js LTS version.
• Chrome current stable version or newer.
• npm

Getting started

Add the following config to your MCP client:

{
  "mcpServers": {
    "chrome-devtools": {
      "command": "npx",
      "args": ["-y", "chrome-devtools-mcp@latest"]
    }
  }
}

[!NOTE] Using chrome-devtools-mcp@latest ensures that your MCP client will always use the latest version of the Chrome DevTools MCP server.

If you are interested in doing only basic browser tasks, use the --slim mode:

{
  "mcpServers": {
    "chrome-devtools": {
      "command": "npx",
      "args": ["-y", "chrome-devtools-mcp@latest", "--slim", "--headless"]
    }
  }
}

See Slim tool reference.

MCP Client configuration

<details> <summary>Amp</summary> Follow https://ampcode.com/manual#mcp and use the config provided above. You can also install the Chrome DevTools MCP server using the CLI:

amp mcp add chrome-devtools -- npx chrome-devtools-mcp@latest

</details> <details> <summary>Antigravity</summary>

To use the Chrome DevTools MCP server follow the instructions from <a href="https://antigravity.google/docs/mcp">Antigravity's docs</a> to install a custom MCP server. Add the following config to the MCP servers config:

{
  "mcpServers": {
    "chrome-devtools": {
      "command": "npx",
      "args": [
        "-y",
        "chrome-devtools-mcp@latest",
        "--browser-url=http://127.0.0.1:9222"
      ]
    }
  }
}

This will make the Chrome DevTools MCP server automatically connect to the browser that Antigravity is using. If you are not using port 9222, make sure to adjust accordingly.

Chrome DevTools MCP will not start the browser instance automatically using this approach because the Chrome DevTools MCP server connects to Antigravity's built-in browser. If the browser is not already running, you have to start it first by clicking the Chrome icon at the top right corner.

</details> <details> <summary>Bob</summary>

Follow the <a href="https://bob.ibm.com/docs/ide/configuration/mcp/mcp-in-bob">IBM Bob MCP guide</a> and add the Chrome DevTools MCP server to your Bob MCP configuration. Use the global config (~/.bob/mcp.json) to apply it across all workspaces, or a project config (.bob/mcp.json) to scope it to one project:

{
  "mcpServers": {
    "chrome-devtools": {
      "command": "npx",
      "args": ["-y", "chrome-devtools-mcp@latest"]
    }
  }
}

You can edit these files from Bob panel → Settings → MCP → Edit Global MCP (or Edit Project MCP). Bob hot-reloads on save. Once the server appears in the MCP tab, switch to the 🌎 Browser Dev mode to get guided browser debugging directly in Bob.

</details> <details> <summary>Claude Code</summary>

Install via CLI (MCP only)

Use the Claude Code CLI to add the Chrome DevTools MCP server (<a href="https://code.claude.com/docs/en/mcp">guide</a>):

claude mcp add chrome-devtools --scope user npx chrome-devtools-mcp@latest

Install as a Plugin (MCP + Skills)

[!NOTE] If you already had Chrome DevTools MCP installed previously for Claude Code, make sure to remove it first from your installation and configuration files.

To install Chrome DevTools MCP with skills, add the marketplace registry in Claude Code:

/plugin marketplace add ChromeDevTools/chrome-devtools-mcp

Then, install the plugin:

/plugin install chrome-devtools-mcp@chrome-devtools-plugins

Restart Claude Code to have the MCP server and skills load (check with /skills).

[!TIP] If the plugin installation fails with a Failed to clone repository error (e.g., HTTPS connectivity issues behind a corporate firewall), see the troubleshooting guide for workarounds, or use the CLI installation method above instead.

</details> <details> <summary>Cline</summary> Follow https://docs.cline.bot/mcp/configuring-mcp-servers and use the config provided above. </details> <details> <summary>Codex</summary> Follow the <a href="https://developers.openai.com/codex/mcp/#configure-with-the-cli">configure MCP guide</a> using the standard config from above. You can also install the Chrome DevTools MCP server using the Codex CLI:

codex mcp add chrome-devtools -- npx chrome-devtools-mcp@latest

On Windows 11

Configure the Chrome install location and increase the startup timeout by updating .codex/config.toml and adding the following env and startup_timeout_ms parameters:

[mcp_servers.chrome-devtools]
command = "cmd"
args = [
    "/c",
    "npx",
    "-y",
    "chrome-devtools-mcp@latest",
]
env = { SystemRoot="C:\\Windows", PROGRAMFILES="C:\\Program Files" }
startup_timeout_ms = 20_000

</details> <details> <summary>Command Code</summary>

Use the Command Code CLI to add the Chrome DevTools MCP server (<a href="https://commandcode.ai/docs/mcp">MCP guide</a>):

cmd mcp add chrome-devtools --scope user npx chrome-devtools-mcp@latest

</details> <details> <summary>Copilot CLI</summary>

Start Copilot CLI:

copilot

Start the dialog to add a new MCP server by running:

/mcp add

Configure the following fields and press CTRL+S to save the configuration:

• Server name: chrome-devtools
• Server Type: [1] Local
• Command: npx -y chrome-devtools-mcp@latest

</details> <details> <summary>Copilot / VS Code</summary>

Install as a Plugin (Recommended)

The easiest way to get up and running is to install chrome-devtools-mcp as an agent plugin. This bundles the MCP server and all skills together, so your agent gets both the tools and the expert guidance it needs to use them effectively.

1. Open the Command Palette (Cmd+Shift+P on macOS or Ctrl+Shift+P on Windows/Linux).
2. Search for and run the Chat: Install Plugin From Source command.
3. Paste in our repository name: ChromeDevTools/chrome-devtools-mcp.

That's it! Your agent is now supercharged with Chrome DevTools capabilities.
