Why cancel_all_orders needs a policy

The action cannot be undone and directly impacts financial positions by removing pending orders that may represent significant financial commitments or hedges. The 'use with caution' warning and emphasis on 'ALL' orders indicates high destructive potential.

From the tool's definition Cancel all pending orders for a category or specific symbol. Use with caution as this cancels ALL open orders matching the criteria.

How to control cancel_all_orders

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 cancel_all_orders:

policy.json

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

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