Proposed fix: [Playwright MCP] Headless browser silently closed after 1 hour idle — next tool call relaunches it and login/page state is lost (--idle-timeout)
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Set --idle-timeout 0 (PLAYWRIGHT_MCP_IDLE_TIMEOUT=0) to disable, or a larger value; use a persistent profile (--user-data-dir) or storage state so re-login is not needed.
Option: Set --idle-timeout 0 (PLAYWRIGHT_MCP_IDLE_TIMEOUT=0) to disable, or a larger value; use a persistent profile (--user-data-dir) or storage state so re-login is not needed. [evidence: official_recommended_action]
Applies when: Long agent sessions with pauses > 1 h using a Playwright MCP-launched headless browser
Steps:
1. Add --idle-timeout=0 to the server args (or PLAYWRIGHT_MCP_IDLE_TIMEOUT=0).
2. Or persist auth via --user-data-dir / --storage-state.
Expected: The error no longer appears.
