Playwriter
remorses
Let AI agents control your existing Chrome via Playwright and MCP - logins and cookies intact.
What is Playwriter?
Playwriter is a Chrome extension plus CLI/MCP server that connects agents to your already-running browser, keeping logins, cookies and extensions intact. Agents get full Playwright API access over a WebSocket relay, usable from both scripts and agent frameworks.
Pros & Cons
Pros
- Reuses authenticated browser sessions - no re-login or cookie-injection hacks
- Very active maintenance with frequent releases
- Dual CLI and MCP interface works from scripts and agent frameworks
Cons
- Low fork count suggests limited third-party/enterprise adoption so far
- Requires a Chrome extension install - friction in locked-down environments
- Desktop-session-centric, not server-side scale automation
