Guardrails
In addition to the 14 universal guardrails, this server has 15 server-specific guardrails across 6 operations.All 15 guardrails are request-time controls focused on physical-world safety — preventing AI from controlling sensitive areas, floors, or security-critical devices (locks, garage doors, gates).
