Why BinanceWalletBrokerWithdraw needs a policy

This tool initiates withdrawals of cryptocurrency or assets from a broker wallet, which constitutes movement of money and financial obligations. The ability for an AI agent to withdraw funds without proper authorization constraints represents critical risk. Even with travel rule compliance features, the core function is transferring financial assets, placing this in the Financial category at critical severity.

From the tool's definition Tool name 'BinanceWalletBrokerWithdraw' combined with description 'Initiate broker withdrawal' directly indicates movement of funds/money from a broker account. The travel rule compliance mention further confirms this is a financial transaction tool.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "BinanceWalletBrokerWithdraw": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}
