Parameters from the server's own tool schema.
This is a straightforward data retrieval operation that queries bank information by code. It has no side effects, does not modify any data, does not execute code or commands, and does not involve financial transactions. It falls squarely into the Read category with low severity due to minimal blast radius if misused by an AI agent.
