Playwright MCP v0.0.84
Playwright MCP v0.0.84 introduces multi-account session isolation in a single browser, runtime URL parameter redaction, bounded search results, and cross-navigation network request retention.
Why this signal matters
Playwright MCP v0.0.84 brings multiple updates to agent browser interactions: - Isolated Contexts: browser tabs with action: 'new' accepts isolatedContext to manage separate cookie and storage contexts within the same browser instance. - URL Param Redaction: Added --redact-url-params (or PLAYWRIGHT MCP REDACT URL PARAMS ) to scrub query/fragment parameter values such as runtime tokens in tool outputs. - Bounded Search & Cross-Navigation Inspection: browser find now accepts maxResults while reporting total matches. browser network requests supports all: true to preserve up to 200 requests across page navigations. - Multi-Language Locators: Tools like browser click now support JavaScript, Python, Java, and C locators in the target parameter alongside snapshot refs and CSS selectors. - Workspace & Storage Handling: Added --ignore-roots to bypass stalling roots/list requests. Added domain and path filtering to browser cookie delete . - Key Fixes: Wait condition logic in browser wait for now treats time as a timeout when text conditions exist; loopback hosts are allowed by default across bind addresses; embedded credentials in --proxy-server are forwarded correctly; and graceful browser closure was implemented for stdio disconnects.
Actionable summary
Playwright MCP v0.0.84 adds isolatedContext support for tabs, maxResults bounding on browser find , retained network request inspection with all: true , language locator support (JS, Python, Java, C ) in element tools, and several bug fixes around loopback host binding, proxy credentials, and wait conditions.

What builders should check
- Use isolatedContext in browser tabs if you need isolated sessions/cookies within the same browser instance.
- Configure --redact-url-params to prevent sensitive tokens or query parameters from showing up in tool responses.
- Pass maxResults to browser find to cap context payload size on high-match terms.
- Enable --ignore-roots if connecting MCP clients stall when querying roots.
