Chrome DevTools MCP

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. Its 40 documented tools cover heapsnapshot, page, performance, take.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Chrome DevTools MCP

Claude Code

claude mcp add chromedevtools-chrome-devtools-mcp -- npx -y chrome-devtools-mcp

Claude Desktop / Cursor / VS Code - add to config

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

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license Apache-2.0 - declared in the repository

npm package chrome-devtools-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.ChromeDevTools is GitHub-verified and matches the repo owner

Limitations (from the README)

[!WARNING] Enabling the remote debugging port opens up a debugging port on the running browser instance. Any application on your machine can connect to this port and control the browser. Make sure that you are not browsing any sensitive websites while the debugging port is open.
