AI agents call get_project_billing_settings 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 billing configuration data for a project. The verb 'get' and the absence of any language suggesting modification, deletion, or financial transaction (e.g., 'apply', 'charge', 'process payment') clearly indicate a read-only operation. Even though it accesses billing-related information, it does not move money, commit financial obligations, or alter state.
From the tool's definition Tool name 'get_project_billing_settings' and description 'Get billing settings for a project' indicate a retrieval operation with no modification or side effects.
