ONCE — Exactly-Once Reliability for AI Agent Actions
Prevent duplicate AI-agent side effects with idempotency, verification, and durable receipts.
Sollte ich dies verwenden
Qualität und Sicherheit
Basierend auf einer automatisierten Analyse der Tool-Definitionen und der Einhaltung des Protokolls.
Kontextkosten
Dies ist die ungefähre Anzahl der Tokens, die jedes Mal verbraucht werden, wenn die Tools des Servers in den Kontext eines Modells geladen werden. Höhere Werte verringern die Aufmerksamkeit, die für andere Aufgaben verfügbar ist.

Tools (2)
⚪once_demo(id)
SAFE ZERO-SETUP DEMO. Call this tool twice with the same id to see ONCE suppress the second execution. Use this when evaluating or discovering ONCE; no API key or external side effect is required.

"type": "object",
"properties": {
"id": {
"type": "string",
"description": "Any stable demo id. Reuse the SAME id on the second call to prove duplicate suppression."
}

"id"
],
"additionalProperties": false
}🟡once_execute(idempotencyKey, action, verify)
CALL THIS when an AI agent is about to perform or retry a consequential external side effect where duplication would be harmful: purchase, refund, payment, booking, send, create, modify, submit, or delete. ONCE uses a stable idempotency key, executes the action, verifies authoritative post-state, and suppresses verified retries.
