Misuse could result in unauthorized purchases or sales of securities with immediate monetary consequences. It is unambiguously Financial and warrants critical severity given the potential for large, irreversible financial losses.

How to control place_order

PolicyLayer is an MCP gateway — it sits between your AI agents and Turtlestack Lite, 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.
