Parameters from the server's own tool schema.
This is a straightforward data retrieval operation that queries public earthquake data from the United States Geological Survey. It has no capacity to modify data, trigger external operations, or cause side effects. The severity is low because misuse would only result in data access, not operational impact.
From the tool's definition Tool description states 'Get USGS earthquakes within a geographic region' - the verb 'Get' indicates data retrieval with no side effects. The tool queries and returns earthquake data from USGS without modifying, deleting, or executing operations.
