Chrome DevTools MCP

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

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.

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.

Install via CLI (MCP only)

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

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

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