Playwright MCP v0.0.81
Playwright MCP v0.0.81 introduces WebMCP support to interact with in-page tools, idle browser timeouts, profile directory selection, and several security and session fixes.
Why this signal matters
Playwright MCP release v0.0.81 adds new tools ( browser webmcp list and browser webmcp call ) allowing agents to discover and invoke tools registered by a webpage via the experimental WebMCP API. Additional updates include the --profile-dir-name flag for selecting Chrome profiles in extension mode, a default 1-hour idle timeout for headless browsers (configurable via --idle-timeout ), and a new only option for --image-responses . Key fixes include resolving symlinks during file access checks to prevent workspace escapes, fixing ENOENT issues for nested output directories, ensuring relative paths resolve against the workspace root for browser file upload and browser drop , isolating DevTools recording sessions across clients under --shared-browser-context , error handling on browser close within shared contexts, a 30-second connection timeout in extension mode, and disabling the Chromium sandbox by default on Linux for bundled builds.
Actionable summary
Playwright MCP v0.0.81 adds browser webmcp list and browser webmcp call for experimental WebMCP API interactions, enables an idle timeout (default 1 hour) for headless browsers via --idle-timeout , resolves workspace escape issues via symlinks, and prevents cross-client recording leakage under --shared-browser-context .

What builders should check
- Verify workspace security assumptions, as symlinks are now resolved to block access outside allowed roots.
- Adjust --idle-timeout (or PLAYWRIGHT MCP IDLE TIMEOUT ) if long-lived headless browser sessions without tool calls are required.
- Update extension-mode configurations with --profile-dir-name if connecting to non-default Chrome profiles.
- Optionally test experimental WebMCP integrations via Chrome and the new browser webmcp list / browser webmcp call tools.
