What batch_cancel_order does on Bybit MCP Server
AI agents call batch_cancel_order to permanently remove resources in Bybit MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why batch_cancel_order is rated Critical
Canceling orders is a destructive operation that cannot be undone—once canceled, orders are removed from the market and cannot be restored to their previous state. This is irreversible data/state destruction in a financial context. Combined with batch capability (canceling multiple orders at once), the blast radius is significantly amplified.
From the tool's definition Tool name 'batch_cancel_order' and description 'Cancel multiple existing orders in a single request' directly indicates irreversible cancellation of financial orders. The ability to cancel 'multiple' orders in batch amplifies the destructive impact.

batch_cancel_order is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
