This is a read-only operation with no ability to modify, delete, or execute external operations. The absence of a description reduces confidence slightly, but the name and server context both point clearly to a Read category. Even if misused by an agent, retrieving price data poses minimal risk.
From the tool's definition Tool name 'get_crypto_prices' indicates retrieval of cryptocurrency price data; no description provided to suggest write, execute, or destructive capabilities. Consistent with the server's stated purpose of providing free utility APIs without side effects.
