Key enhancements include: - Context Isolation : browser tabs (action: \"new\" ) accepts isolatedContext , allowing separate browser sessions with isolated cookies and storage under distinct context names (or fallback to \"default\" ). - URL Param Redaction : The --redact-url-params flag (or PLAYWRIGHT MCP REDACT URL PARAMS ) redacts dynamic parameters (e.g., access tokens, codes) in query and fragment components in tool responses. - Bounded Searches : browser find introduces a maxResults integer parameter to limit response sizes while reporting the total match count. - Cross-Navigation Network History : browser network requests accepts all: true to retain up to 200 requests across page navigations with stable indexes. - Multi-language Locators : Element tools like browser click now support raw locators written in JavaScript, Python, Java, and C , alongside snapshot refs and CSS selectors. - Workspace Root Handling : Added --ignore-roots (or PLAYWRIGHT MCP IGNORE ROOTS=true ) to use the current working directory if a client stalls on roots/list . - Granular Cookie Management : browser cookie delete allows optional domain and path filters. Bug fixes include corrected handling for browser wait for (treating time as a timeout when combined with text conditions), loopback host access defaults for HTTP clients, proxy credential parsing, improved cookie filtering, and graceful browser shutdown on client disconnect.","sponsors":[]}
