Parameters from the server's own tool schema.
This tool retrieves historical scan data from urlscan.io. It queries an external service to fetch information about previous URL scans but does not execute new scans, modify data, delete records, or trigger financial transactions. The action is read-only with minimal side effects. Severity is low because misuse would only expose publicly available scan metadata, not cause harm through execution or data destruction.
From the tool's definition Tool is named 'urlscan_search' and described as 'Search urlscan.io scan results' — the verb 'search' and 'scan results' indicate querying/retrieving data without modification or execution.
