List all open tabs with their URLs and titles.
AI agents call browser_list_tabs to retrieve information from Daytona Playwright MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It performs no modifications, deletions, code execution, or external actions—only read access to browser metadata. Misuse risk is minimal; an agent could learn what tabs are open but cannot manipulate them or cause harm through listing alone.
