api_ultrade_wallet_withdraw_message

THE RISK

Critical Risk

This tool generates a withdrawal message, which is a step in the process of withdrawing funds from a wallet. Even though it only generates a message rather than executing the transaction directly, it is a preparatory step for a financial operation (moving funds out of a wallet). In the context of a BNB Chain MCP server that handles token transactions, this is part of a financial workflow.

HOW TO CONTROL API_ULTRADE_WALLET_WITHDRAW_MESSAGE

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

policy.json

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

Any call to api_ultrade_wallet_withdraw_message is blocked until a human approves it. The rest of the server keeps working.
