POLICY

How to control place_order

PolicyLayer is an MCP gateway — it sits between your AI agents and 富途 MCP 服务器 (Futu MCP Server), and nothing reaches the server without passing your rules. This is the rule we recommend for place_order:

policy.json

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

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