This tool performs a query operation that fetches publicly available or user-accessible interest rate data. It neither modifies state, executes code, deletes data, nor moves funds. The worst case of misuse would be an agent acting on retrieved rate information, but the tool itself is a simple read operation with minimal blast radius.
From the tool's definition Tool name 'BinanceGetBorrowInterestRate' and description 'Retrieves the interest rates' indicates data retrieval with 'no side effects'. The description confirms it 'provides' rates without modifying, creating, or executing anything.
