AI agents call get_fund_ranking to retrieve information from Sfc Data without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays fund ranking data sorted by various metrics (price gains, losses, etc.). It is a read-only query operation with no side effects—it does not create, modify, delete data, execute code, or involve financial transactions. The low severity reflects minimal risk of misuse even by an unrestricted AI agent.
