Get all open browser tabs with their IDs, URLs, and titles.
AI agents call browser_get_tabs to retrieve information from Cdp Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about open tabs (IDs, URLs, titles) with no side effects or state modifications. It is a simple information query operation, fitting the Read category. Severity is low because the information exposed is limited to tab metadata already visible to the user, with minimal sensitive data leakage risk in typical usage.
