为什么值得关注
Playwright MCP v0.0.81 introduces new experimental WebMCP capabilities allowing models to inspect ( browser webmcp list ) and execute ( browser webmcp call ) tools exposed by the webpage itself. It also implements an automatic 1-hour idle shutdown for headless server-managed browsers (configurable via --idle-timeout / PLAYWRIGHT MCP IDLE TIMEOUT ), with 0 disabling it. In extension mode, users can specify profile directories with --profile-dir-name . Security and bug fixes include preventing directory traversal via symlinks outside the workspace root, handling nested output file paths properly, preventing browser close from breaking shared context sessions, isolating client recordings under --shared-browser-context , timing out stuck extension connections after 30 seconds, and disabling the Chromium sandbox by default on Linux for the bundled binary.
可执行摘要
Playwright MCP v0.0.81 adds browser webmcp list and browser webmcp call for page-registered WebMCP tools, sets a default 1-hour idle timeout on server-launched headless browsers ( --idle-timeout ), adds --profile-dir-name , tightens symlink checking against workspace escaping, and resolves multiple shared-context and path resolution issues.

开发者应核对什么
- Configure --idle-timeout (or PLAYWRIGHT MCP IDLE TIMEOUT ) if headless browsers need to stay active beyond 1 hour of inactivity.
- Verify workspace file interactions if relying on symlinks, as paths resolving outside allowed roots are now blocked.
- Use --profile-dir-name (or PLAYWRIGHT MCP PROFILE DIR NAME ) when targeting specific Chrome profiles in extension mode.
- Note that Linux bundled Chromium now disables the sandbox by default due to a missing setuid sandbox helper.
