Parameters from the server's own tool schema.
This tool queries a REST Countries API to retrieve country information by name. It has no capability to modify, delete, or execute operations. The blast radius of misuse is minimal—an agent could retrieve unnecessary country data but cannot cause harm. Low severity due to the read-only, informational nature of the operation.
From the tool's definition Tool description states 'Get a country by name from REST Countries' - a retrieval operation with no modification or side effects. The verb 'Get' and the passive data query nature indicate read-only access to a public country database.
