Playwright MCP

<div align="center"> <img src="assets/playwright-logo.png" alt="Playwright Logo" width="200"> </div>

A Model Context Protocol (MCP) server that provides browser automation capabilities using Playwright. Enables LLMs to interact with web pages through structured accessibility snapshots, bypassing the need for screenshots or visually-tuned models.

Features

• Fast and lightweight - Uses Playwright's accessibility tree, not pixel-based input
• LLM-friendly - No vision models needed, operates purely on structured data
• Deterministic - Avoids ambiguity common with screenshot-based approaches

Requirements

• Node.js 18 or newer
• Any MCP client (VS Code, Cursor, Claude Desktop, Windsurf, etc.)

Quick Start

Add to your MCP client configuration:

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": ["playwright-mcp@latest"]
    }
  }
}

VS Code / Cursor

Go to Settings → MCP → Add Server and configure manually using the standard config above.

Configuration

Basic Options

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": [
        "playwright-mcp@latest",
        "--headless",              // Run browser in headless mode
        "--browser", "chromium",    // Choose browser: chromium, firefox, webkit
        "--viewport-size", "1280x720" // Set viewport size
      ]
    }
  }
}

Browser Extension (Connect to Existing Browser)

Connect to your existing Chrome/Edge browser with logged-in sessions:

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": ["playwright-mcp@latest", "--extension"]
    }
  }
}

See extension/README.md for extension installation.

Isolated Sessions

Run each session in an isolated browser context:

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": [
        "playwright-mcp@latest",
        "--isolated",
        "--storage-state", "path/to/storage.json"
      ]
    }
  }
}
