WHAT IT DOES

What crow_browser_load_session does on Crow

AI agents call crow_browser_load_session to retrieve information from Crow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why crow_browser_load_session is rated Low

This tool retrieves and restores stored session data (cookies and storage). While it is fundamentally a Read operation, the medium severity reflects that session restoration could expose sensitive authentication tokens or user data if misused by an AI agent without proper safeguards. The tool does not create, modify, delete, or execute code; it only loads previously saved state.

From the tool's definition Tool name and description indicate 'Restore a previously saved session (cookies and storage)' — a retrieval operation that loads existing session data without modifying or deleting it.
