Playwright MCP

Automate browser interactions and run end-to-end tests through the Model Context Protocol, enabling AI agents to verify UI behavior in real browsers.

Overview

Playwright MCP gives AI agents the ability to launch real browser instances, navigate pages, interact with elements, and capture screenshots or test results. This transforms your AI coding agent from a text-only tool into one that can actually see and verify your web application's behavior.

The server implements the Model Context Protocol to expose Playwright's full automation API. Your agent can write end-to-end tests, run them against your development server, interpret the results, and fix failing assertions, all in a single conversation. It supports Chromium, Firefox, and WebKit, ensuring cross-browser compatibility testing is just a prompt away.

This integration is particularly valuable during development iterations. Instead of manually checking if a UI change works, you can ask your agent to verify it by actually running the application in a browser and confirming the expected behavior visually.
