AI agents use postCryptoLoanFlexibleBorrow to commit financial operations through Bybit MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool initiates a crypto loan/borrowing operation on the Bybit exchange, which is a financial commitment. Borrowing creates a financial obligation (repayment of principal plus interest), and misuse by an AI agent could result in significant financial liability. It is clearly in the Financial category as it moves/commits financial resources and creates ongoing interest obligations.
