 OpenCLI connects to your browser through the Playwright MCP Bridge extension.
+It prefers an existing local/global `@playwright/mcp` install and falls back to `npx -y @playwright/mcp@latest` automatically when no local MCP server is found.

 OpenCLI 通过 Playwright MCP Bridge 扩展与你的浏览器通信。
+它会优先复用本地或全局已安装的 `@playwright/mcp`，如果没有嗅探到可用 MCP server，则会自动回退到 `npx -y @playwright/mcp@latest` 启动。
