RECOMMENDED RULE

The rule that runs instance_messages safely

instance_messages Allowed

instance_messages is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "instance_messages": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ProAgentStore, apply this rule, and every instance_messages call is checked against it from then on.
