WHAT IT DOES

What BinanceFuturesUSDMListenKeyClose does on Binance MCP Server

AI agents use BinanceFuturesUSDMListenKeyClose to create or update resources in Binance MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Binance MCP Server environment.

RISK

Why BinanceFuturesUSDMListenKeyClose is rated Medium

Closing a listen key/user data stream is a reversible write operation that terminates a WebSocket stream subscription. It does not delete financial data, execute trades, or move money — it simply ends a streaming session. A new listen key can be created at any time, making this non-destructive. Severity is low as misuse would only disrupt real-time data feeds, not cause financial or data loss.
