Why cancel_order needs a policy

Cancelling an order is an irreversible action — once a spot order is cancelled on Binance, it cannot be reinstated. The sibling tool 'cancel_futures_order' confirms the pattern that 'cancel_order' cancels spot orders. While not deleting data in a database sense, it permanently terminates a financial instruction.

From the tool's definition Tool name 'cancel_order' on a Binance spot trading server; sibling tool 'cancel_futures_order' exists, suggesting this cancels spot orders. Description is empty.

How to control cancel_order

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

policy.json

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

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