This tool queries financial account information but performs no writes, deletions, or movements of money. It is a read-only operation that returns data. While it concerns financial accounts, it does not commit financial obligations or move funds, so it is categorized as Read rather than Financial. The low severity reflects minimal risk from an AI agent querying balances, though the information returned is sensitive.
