概要
Ever tried using Cursor or Claude to write Playwright tests? Yeah, it's kind of a mess. Why? Because your AI assistant has no clue what's on your web page. It's like trying to describe a painting to someone who's blindfolded. The result? - → The AI is guessing selectors, and it gets them wrong. - → You spend more time fixing tests than writing them. - → The AI can't "see" what's happening, so you end up doing all the heavy lifting. Wouldn't it be nice if your AI could actually understand your web page instead of just making educated guesses? playwright-mcp gives your AI assistant superpowers by making the browser fully visible to it. Instead of working in the dark, your AI assistant now has real-time access to the page DOM, elements, and interactions. Once installed, playwright-mcp spins up a Playwright-controlled browser and gives your AI assistant full access to it. This unlocks: 1.

How to Use playwright-mcp?
Introduction
Ever tried using Cursor or Claude to write Playwright tests? Yeah, it’s kind of a mess.
Why? Because your AI assistant has no clue what’s on your web page. It’s like trying to describe a painting to someone who’s blindfolded. The result?
- Flaky tests → The AI is guessing selectors, and it gets them wrong.
- Broken scripts → You spend more time fixing tests than writing them.
- Debugging nightmares → The AI can’t “see” what’s happening, so you end up doing all the heavy lifting.
Wouldn’t it be nice if your AI could actually understand your web page instead of just making educated guesses?
Enter playwright-mcp !
playwright-mcp gives your AI assistant superpowers by making the browser fully visible to it. Instead of working in the dark, your AI assistant now has real-time access to the page DOM, elements, and interactions.
How playwright-mcp Works (AKA How We Fix This Mess)
Once installed, playwright-mcp spins up a Playwright-controlled browser and gives your AI assistant full access to it. This unlocks:

- Taking screenshots → Capture elements or full pages so your AI gets actual visual context (no more guessing).
- Extracting the DOM → Grab the entire HTML structure so the AI can generate rock-solid selectors.
- Executing JavaScript → Run custom JS inside the browser for debugging, automation, or just for fun.
