Introduced 2026-01-31 · score 0.96

HOW TO USE IT

When debugging or reviewing a web application, start a video recording, perform the browser flow, then stop the recording to save the video. In Playwright MCP, enable the capability with `--caps=devtools` and use the video tools.

playwright-cli open playwright.dev playwright-cli video-start # Perform the browser flow playwright-cli video-stop
playwright-cli video-start <filename>.webm # Perform the browser flow playwright-cli video-stop
# Start the MCP server with the devtools capability enabled: --caps=devtools browser_start_video {} # Perform the browser flow browser_stop_video {}
