AI agents call get_contact_phones to retrieve information from Filevine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves phone numbers associated with a contact in a legal case management system. It is a read-only query operation that accesses data without creating, modifying, or deleting anything. The severity is low because phone number exposure in a case management system, while potentially sensitive, is contained and does not enable financial transactions, code execution, or data destruction.
From the tool's definition Tool name 'get_contact_phones' and description 'Get all phone numbers for a contact' indicate retrieval of existing contact information with no modification or side effects.
