AI agents call binance_futures_klines to retrieve information from Binance without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is fundamentally a read operation that retrieves historical price data for analysis. It performs no write, execute, destructive, or financial operations itself. However, it is classified as 'high' severity rather than 'low' because the data it provides is specifically for futures trading decisions involving leverage, margin requirements, liquidation risks, and funding costs.
From the tool's definition Tool name is 'binance_futures_klines' and description states it 'gets futures market kline (candlestick) historical data' (获取合约市场的K线历史数据). This is a data retrieval operation with no modifications.
