Before you connect
Questions about Idempotency Key Enforcer.
The practical details behind the request, access and result.
How does Idempotency Key Enforcer prevent double payments?
It identifies if an agent is attempting to use a signature that has already been successfully processed, stopping the second attempt before it hits your payment gateway.
Can I see how many duplicate requests were blocked by Idempotency Key Enforcer?
Yes, you can check the current cache statistics to see exactly how many hits and misses have occurred recently.
What happens if my agent retries a task after a long delay?
The Connector uses an LRU cache, so if enough new tasks have passed through, the old signature might be evicted, allowing a new attempt.
Does Idempotency Key Enforcer work with any AI client?
Yes, it works with any compatible client like Claude, Cursor, or Windsurf as long as they can connect to the Vinkius catalog.
How do I reset my agent's execution history in Idempotency Key Enforcer?
You can simply trigger a command to wipe the entire cache and start fresh.
How does the enforcer identify duplicate operations?
It uses an operation signature, which is a deterministic hash of the function name and its sorted arguments. If this exact signature exists in the cache, it is flagged as a duplicate.
What happens when the cache reaches its capacity?
The server implements an LRU (Least Recently Used) eviction policy. When the limit is reached, the oldest, least-accessed entries are removed to make room for new operations.
Can I see how many hits or misses have occurred?
Yes. By calling the get_cache_stats capability, you can retrieve real-time telemetry including hit counts, miss counts, and eviction counts.
