AI agents call snow_get_pending_approvals to retrieve information from Serac without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves approval status information from ServiceNow without creating, modifying, deleting, or executing any operations. It is a straightforward data query operation that presents minimal risk even if misused by an AI agent, as the worst case is reading information the user may already have access to.
From the tool's definition Tool name 'snow_get_pending_approvals' and description 'Get pending approvals for user' indicate a retrieval operation. The verb 'Get' and the absence of any modification language confirm this is a query-only action with no side effects.
