RISK

Why crypto_price is rated Low

This tool retrieves public market data from an external API (CoinGecko) without modifying, deleting, or executing any operations. It has no blast radius if misused by an AI agent—the worst outcome is stale or incorrect price data being returned. Classification as Read is appropriate.

From the tool's definition Tool name 'crypto_price' and description 'Get cryptocurrency prices from CoinGecko' indicate a data retrieval operation with no side effects. The verb 'Get' and the singular purpose of retrieving price information confirm this is a query-only action.
