BinancePortfolioMarginCmCancelOrder

THE RISK

Critical Risk

Cancelling an active order is an irreversible action in financial context — once cancelled, the order is gone and cannot be reinstated. It also has financial implications as it terminates a committed trading position. While it doesn't move money directly, it irreversibly removes an active order. Given the financial/trading context, this warrants high severity.

HOW TO CONTROL BINANCEPORTFOLIOMARGINCMCANCELORDER

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

policy.json

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

BinancePortfolioMarginCmCancelOrder 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 BNB Chain MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
