为什么值得关注
Playwright MCP version 0.0.78 brings new features and stability fixes to the browser automation agent tooling. A new browser find tool allows searching accessibility snapshots by text or regex, returning matching nodes with surrounding context snippets instead of full snapshots to reduce context costs. General accessibility snapshots were distilled to lower verbosity and token usage. For device configuration, --mobile and --device CLI options enable mobile emulation. browser navigate now reports non-2xx HTTP navigation statuses and avoids crashes when navigation closes the last tab. Other fixes include enabling the Chromium sandbox by default, awaiting page initialization before taking screenshots upon opening, properly saving videos across multiple tabs, passing noDefaults for CDP connections, closing isolated HTTP contexts upon disconnect, and syncing the client event stream before sending server-to-client requests.
