Playwright MCP

What is Playwright MCP

Playwright MCP is a Model Context Protocol server that enables browser automation using Playwright’s accessibility tree, providing a structured way to interact with web pages without relying on visual models or screenshots.

Use cases

It is designed for fast and reliable browser automation in scenarios like testing web applications, web scraping, and any other interactive tasks that require precise control over web elements using structured data.

How to use

To use Playwright MCP, install the server in your preferred development environment, configure its settings, and connect it to an MCP client like VS Code, Cursor, or others. After setting it up, you can perform various actions on web pages by sending structured commands.

Key features

Key features include fast and lightweight interactions using the accessibility tree, deterministic tool application that avoids the ambiguities of pixel-based approaches, and the ability for large language models (LLMs) to operate without vision models, improving accessibility and performance.

Where to use

Playwright MCP can be used in various development and testing environments where browser automation is required, particularly in code editors, integrated development environments (IDEs), and continuous integration/continuous deployment (CI/CD) pipelines, enhancing automation capabilities for web applications.

Key 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 tool application. Avoids ambiguity common with screenshot-based approaches.

Requirements

• Node.js 18 or newer
• VS Code, Cursor, Windsurf, Claude Desktop or any other MCP client
