Let agents control a logged-in Chrome browser through Playwriter MCP

Use Playwriter to give MCP-compatible agents a bounded, stateful Playwright control surface over an operator-approved Chrome session.

Prerequisites

Playwriter Chrome extension and CLI; MCP-compatible client when using MCP mode; Chrome/Chromium browser session

Installation

Use the upstream install or setup path that matches your environment:

• npm i -g playwriter
• npx -y skills add remorses/playwriter
• npx -y traforo -p 19988 -t my-machine -- npx -y playwriter serve --token <secret>
• npx -y playwriter serve --host 127.0.0.1

Requirements and caveats from upstream:

• Variables in scope: page, context, state (persists between calls), require, and Node.js globals.

Basic usage or getting-started notes:

• Install Extension from Chrome Web Store

• Click extension icon on a tab → turns green when connected

• Install the CLI and start automating the browser:
