Why BinancePortfolioMarginUmCancelOrder needs a policy

Cancelling an active futures order is an irreversible action — once cancelled, the order cannot be reinstated. This removes an existing financial position/order from the market, which cannot be undone. While it doesn't directly move money, it permanently destroys an active order in a financial context, placing it at Destructive severity. The financial nature of futures trading elevates the blast radius to high.

POLICY

How to control BinancePortfolioMarginUmCancelOrder

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for BinancePortfolioMarginUmCancelOrder:

policy.json

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

BinancePortfolioMarginUmCancelOrder disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
