Отменить стоп-заявку в Т-Инвестициях
AI agents call cancel_stop_order to permanently remove resources in T-Invest MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a stop order cannot be undone once confirmed; the stop order is permanently removed from the system. In a trading context, this could expose a portfolio to unintended market risk (e.g., removing a stop-loss). This qualifies as Destructive due to the irreversible nature of the cancellation, and rates high severity given potential financial exposure from removing risk management orders.
From the tool's definition 'Отменить стоп-заявку' means 'Cancel stop order' — cancelling a stop order is an irreversible action that removes a protective or speculative trading instruction permanently
