A support agent refunds on its own, and the big one waits for you
You want the agent to finish routine refunds by itself, larger ones to wait for you, and the agent never to hold the payment credential.
A support operator asks an Agno agent (Claude on Amazon Bedrock) to process refunds. Its tools reach Stripe (test mode) only through the KIFF MCP gateway. A €24 refund is inside its Card and goes through; an €86 refund is over the €50 limit, so KIFF holds it and nothing reaches Stripe. The owner approves it in KIFF, and the agent, which was waiting in the same conversation, finishes the refund once. Then the Card's record and the agent's page. Real model, real gateway, Stripe test mode; recorded 2 October 2026.
