Analyze Arc tabs for duplicates, stale tabs, junk candidates, and missing URLs.
AI agents call arc_analyze_tabs to retrieve information from Arc Browser MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and examines tab metadata to generate analytical insights. It has no side effects on the browser state, tabs, or any external systems. The analysis is purely informational, making it a read-only operation with minimal security risk. Severity is low because misuse would only expose information about the user's browsing habits, not enable harmful actions or data loss.
From the tool's definition Tool performs analysis of tabs to identify duplicates, stale tabs, junk candidates, and missing URLs. The verb 'analyze' indicates inspection and examination without modifying or executing actions.
