Why cancelAllSpreadOrders needs a policy

Canceling orders is destructive because it irreversibly terminates open trading orders. While the action itself can technically be reversed by placing new orders, the cancellation itself cannot be undone and represents an immediate, irreversible change to the user's active trading positions. The word 'all' and 'spread orders' indicates bulk operation capability.

From the tool's definition The tool name is 'cancelAllSpreadOrders' and the description states it 'Cancel[s] all open spread trading orders'.

POLICY

How to control cancelAllSpreadOrders

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 cancelAllSpreadOrders:

policy.json

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

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