What citrex_cancel_order does on SEI MCP Server V2
AI agents call citrex_cancel_order to permanently remove resources in SEI MCP Server V2, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why citrex_cancel_order is rated Critical
Cancelling an open order permanently removes it; there is no 'undo' once the cancellation is submitted on-chain. This maps to Destructive. Severity is medium because while no funds are directly lost, a mistakenly cancelled order could result in missed trades or require re-submission, and in a fast-moving DeFi market this can have meaningful financial consequences.
From the tool's definition 'Cancels an existing open order' — cancellation of an order is an irreversible action that removes the order from the book and cannot be undone.
