This tool retrieves publicly available business registry information with no side effects. It queries existing data without creating, modifying, deleting, or executing operations. The blast radius of misuse is minimal—an attacker could only gather publicly available business information, which poses no confidentiality risk (data is already public) and no integrity or availability risk.
From the tool's definition Tool performs 'search' and 'returns' data (entity id, name, type, status, jurisdiction, formation date, address, registered agent) from public State Secretary-of-State business registries. No modification, deletion, or execution capability described.
