WHAT IT DOES

What cancelRfq does on Bybit MCP Server

AI agents call cancelRfq 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.

RISK

Why cancelRfq is rated Critical

Cancelling an active RFQ is an irreversible action in the trading workflow. Once cancelled, the RFQ (Request for Quote) cannot be restored, making this a Destructive operation. The blast radius is high because it could disrupt active trading negotiations or hedging strategies on the Bybit exchange.

From the tool's definition Cancel an active RFQ — cancellation of a trading request-for-quote is irreversible; the RFQ cannot be reinstated once cancelled.
