Cancelar una operación específica
AI agents call cancelar_operacion to permanently remove resources in IOL MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a trading operation in a brokerage/investment platform is an irreversible action. Once a trade order is cancelled, it cannot be undone, and market conditions may have changed, making it impossible to restore the original state. Given the financial trading context of IOL (InvertirOnline), this action has high blast radius as it could cancel active buy/sell orders with financial consequences.
From the tool's definition 'Cancelar una operación específica' — cancels a specific operation, which is irreversible in a financial trading context
