WHAT IT DOES

What BinanceFuturesKeepAliveListenKey does on Binance MCP Server

AI agents invoke BinanceFuturesKeepAliveListenKey to trigger actions in Binance MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why BinanceFuturesKeepAliveListenKey is rated High

This tool triggers an external operation (renewing/extending a session key on Binance's servers). It doesn't read data, write persistent data, or perform financial operations — it maintains an active connection by pinging an external service. Classified as Execute due to the external side-effect of session extension. Severity is low since misuse would at worst keep a stream alive unnecessarily or cause it to expire.

From the tool's definition Keepalive a USD-M Futures user data stream listen key. Extends the validity by 60 minutes.
