Parameters from the server's own tool schema.
This tool performs a read-only operation that returns a response (similar to consulting a Magic 8-Ball toy). It has no side effects, does not modify state, does not execute code or external commands, and does not involve financial operations. The low severity reflects that misuse poses minimal risk—an agent calling this repeatedly would only receive harmless responses.
