binance_cancel_order

THE RISK

Critical Risk

Cancelling an order is an irreversible action that terminates a financial commitment on an exchange. While it doesn't move money directly, it destroys an existing open order which cannot be undone once cancelled. Given the financial context (Binance trading orders) and irreversibility, Destructive is the most appropriate category, with high severity due to potential market and financial impact if misused.

From the tool's definition Cancel an open order by orderId or clientOrderId

HOW TO CONTROL BINANCE_CANCEL_ORDER

PolicyLayer is an MCP gateway — it sits between your AI agents and Agenti, and nothing reaches the server without passing your rules. This is the rule we recommend for binance_cancel_order:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "binance_cancel_order"
  ]
}

binance_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.

Create a free account and register Agenti — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
