Why create_order needs a policy

Despite the empty description, the tool name 'create_order' combined with the server context (Binance cryptocurrency exchange, trading operations) makes it highly likely this tool places buy/sell orders on the exchange. This is a financial action with critical severity as it can commit real funds to trades.

From the tool's definition Tool name 'create_order' on a Binance cryptocurrency exchange server described as enabling 'trading operations'. Order creation on a financial exchange constitutes a financial commitment.

POLICY

How to control create_order

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

policy.json

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

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