WHAT IT DOES

What list_transactions does on Waiaas

AI agents call list_transactions to retrieve information from Waiaas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_transactions is rated Low

This tool retrieves or queries transaction data from the wallet without creating, modifying, or deleting any data. Even in a financial context (crypto wallet), listing historical transactions is a read operation with no blast radius. The empty description reduces confidence slightly, but the naming pattern is clear.

From the tool's definition Tool name 'list_transactions' indicates data retrieval with no side effects. Description is empty, but the verb 'list' is a strong signal for read-only operations that query transaction history without modifying state.

list_transactions Allowed

list_transactions is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
