Chrome DevTools MCP

Chrome DevTools MCP

chrome-devtools-mcp lets your coding agent (such as Gemini, 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.

Tool reference | Changelog | Contributing | Troubleshooting

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 the browser console.
• 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.

Requirements

• Node.js v20.19 or a newer latest maintenance 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.

MCP Client configuration

Amp 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

Antigravity

To use the Chrome DevTools MCP server follow the instructions from Antigravity's docs to install a custom MCP server. Add the following config to the MCP servers config:

{

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

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.

Claude Code Use the Claude Code CLI to add the Chrome DevTools MCP server ( guide ):

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

Cline Follow https://docs.cline.bot/mcp/configuring-mcp-servers and use the config provided above.

Codex Follow the configure MCP guide 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

Copilot CLI

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

Copilot / VS Code Follow the MCP install guide , with the standard config from above. You can also install the Chrome DevTools MCP server using the VS Code CLI:

  code --add-mcp '{"name":"chrome-devtools","command":"npx","args":["chrome-devtools-mcp@latest"]}'

Cursor

Click the button to install:

Or install manually:

Go to Cursor Settings -> MCP -> New MCP Server. Use the config provided above.

Factory CLI Use the Factory CLI to add the Chrome DevTools MCP server ( guide ):

droid mcp add chrome-devtools "npx -y chrome-devtools-mcp@latest"

Gemini CLI Install the Chrome DevTools MCP server using the Gemini CLI.

Project wide:

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

Globally:

gemini mcp add -s user chrome-devtools npx chrome-devtools-mcp@latest

Alternatively, follow the MCP guide and use the standard config from above.

Gemini Code Assist Follow the configure MCP guide using the standard config from above.

JetBrains AI Assistant & Junie

Go to Settings | Tools | AI Assistant | Model Context Protocol (MCP) -> Add. Use the config provided above. The same way chrome-devtools-mcp can be configured for JetBrains Junie in Settings | Tools | Junie | MCP Settings -> Add. Use the config provided above.

Kiro

In Kiro Settings, go to Configure MCP > Open Workspace or User MCP Config > Use the configuration snippet provided above.

Or, from the IDE Activity Bar > Kiro > MCP Servers > Click Open MCP Config. Use the configuration snippet provided above.

Qoder

In Qoder Settings, go to MCP Server > + Add > Use the configuration snippet provided above.

Alternatively, follow the MCP guide and use the standard config from above.

Visual Studio

Click the button to install:

Warp

Go to Settings | AI | Manage MCP Servers -> + Add to add an MCP Server. Use the config provided above.

Windsurf Follow the configure MCP guide using the standard config from above.

Your first prompt

Enter the following prompt in your MCP Client to check if everything is working:

Check the performance of https://developers.chrome.com

Your MCP client should open the browser and record a performance trace.

[!NOTE]

The MCP server will start the browser automatically once the MCP client uses a tool that requires a running browser instance. Connecting to the Chrome DevTools MCP server on its own will not automatically start the browser.

Configuration

The Chrome DevTools MCP server supports the following configuration option:

• `--browserUrl`, `-u` Connect to a running Chrome instance using port forwarding. For more details see: https://developer.chrome.com/docs/devtools/remote-debugging/local-server.
• Type: string

• `--wsEndpoint`, `-w` WebSocket endpoint to connect to a running Chrome instance (e.g., ws://127.0.0.1:9222/devtools/browser/ ). Alternative to --browserUrl.
• Type: string

• `--wsHeaders` Custom headers for WebSocket connection in JSON format (e.g., '{"Authorization":"Bearer token"}'). Only works with --wsEndpoint.
• Type: string

• `--headless` Whether to run in headless (no UI) mode.
• Type: boolean
• Default: false

• `--executablePath`, `-e` Path to custom Chrome executable.
• Type: string

• `--isolated` If specified, creates a temporary user-data-dir that is automatically cleaned up after the browser is closed.
• Type: boolean
• Default: false

• `--channel` Specify a different Chrome channel that should be used. The default is the stable channel version.
• Type: string
• Choices: stable, canary, beta, dev

• `--logFile` Path to a file to write debug logs to. Set the env variable DEBUG to * to enable verbose logs. Useful for submitting bug
