Create a refund for a Paystack transaction.
AI agents use paystack_refund to commit financial operations through Africa Payments MCP — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool directly moves money by reversing a financial transaction and returning funds to a customer. Refunds are financial obligations that commit real monetary value. Even if refunds are reversible, they constitute financial operations that could result in significant monetary loss if misused by an agent (e.g., refunding large transaction amounts without authorization or refunding the wrong transactions).
From the tool's definition Tool name contains 'refund' and description states 'Create a refund for a Paystack transaction.' The server description explicitly identifies this as part of a payment provider interface for processing payments and managing transactions.
