How to control transfer_create

policy.json

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

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