THE RISK

Critical Risk

Why cancelSpreadOrder needs a policy

Cancelling a trading order is an irreversible action — once cancelled, the order cannot be reinstated. This affects live trading operations on a cryptocurrency exchange, and misuse could disrupt trading strategies or cause financial harm by removing open orders at critical market moments. While not directly moving money, it irreversibly terminates an order, classifying it as Destructive with high severity.

From the tool's definition Cancel a single spread trading order by its order ID or custom order link ID. Cancel an open limit order that has not yet been fully filled.

POLICY

How to control cancelSpreadOrder

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

policy.json

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

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