anular_recibo
AI agents call anular_recibo to permanently remove resources in MCP Officegest — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Voiding or annulling a receipt is typically an irreversible financial document operation. In accounting systems, annulling a receipt cancels a payment record and cannot be undone. This sits at the boundary of Destructive and Financial; since it voids a financial document (potentially reversing a payment record), Financial is the most severe applicable category. However, without a description, confidence is reduced.
From the tool's definition Tool name 'anular_recibo' translates from Portuguese as 'cancel/void receipt' — 'anular' means to annul/void/cancel, 'recibo' means receipt.
