Get the total USD value of assets in the master account and all sub-accounts.
AI agents call binance_us_subaccount_summary to retrieve information from Sperax Ecosystem Crypto & DeFI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and aggregates financial information (USD asset values across accounts) but does not execute transactions, modify balances, transfer funds, or commit financial obligations. While it accesses sensitive financial data, the operation itself is non-destructive and read-only. Severity is low because misuse by an AI agent would expose information rather than cause financial loss or irreversible damage.
From the tool's definition Tool description states 'Get the total USD value of assets' — a query operation that retrieves account data without modifying, deleting, or moving funds. The verb 'Get' indicates read-only data retrieval.
