AI agents call cancel_order to permanently remove resources in Mcp Binance Futures — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling an order on a futures trading platform is an irreversible action — once cancelled, the order cannot be restored. The server context (order management on Binance USDT-M Futures) and the sibling tool 'cancel_all_orders' confirm this is an order cancellation tool. While it doesn't directly move money, it destroys an existing market instruction irreversibly.

"version": "1",
"default": "deny",
"hide": [
"cancel_order"
]
}cancel_order disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
