THE RISK

Why create_order needs a policy

Creating a trading order on a crypto platform directly commits financial resources. Given the server context of autonomous trading execution with on-chain operations, this tool can initiate irreversible financial transactions. The description is minimal but the server context and sibling tools (execute_approved_order, execute_dex_swap, cancel_order) confirm this is a financial order creation tool.

From the tool's definition 'Creates an order' on a server described as supporting 'autonomous trading agent execution' and 'on-chain data'

Documented attack patterns abuse exactly the kind of access create_order gives an agent:

POLICY

How to control create_order

PolicyLayer is an MCP gateway — it sits between your AI agents and Crypto Multi-MCP Hub, 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
