Overview
Playwriter connects to your running Chrome instance instead of spawning a fresh browser. This fundamental difference enables unique advantages:
- Your existing session: Extensions, logins, and cookies already loaded
- Bot detection bypass: Disconnect extension to appear as regular browsing
- Memory efficiency: One Chrome instance instead of two
- Seamless collaboration: Same browser window you’re already using

Key Advantages
Memory Efficiency
Other browser MCPs spawn a fresh Chrome instance, doubling memory usage. Playwriter connects to your existing browser.
Login State
Start automating immediately without logging into every service. Your cookies, sessions, and auth tokens are already there.
Bot Detection
Fresh browser profiles are instantly flagged. With Playwriter, disconnect the extension to appear as regular browsing.
Collaboration
Watch automation happen in the same browser window you’re using. No switching between windows or trying to figure out what the agent did.
Full Playwright API
Unlike limited tool-based approaches, Playwriter exposes the complete Playwright API through a single execute tool.
