List Vulnerability Response notification definitions (sysevent_email_action) scoped to the VR
AI agents call list_vr_notifications to retrieve information from ServiceNow-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing Vulnerability Response notification configurations without modifying, deleting, or executing any operations. It is a straightforward read operation with no side effects or ability to alter system state. The blast radius if misused is minimal—an agent could only view notification metadata without causing harm.
From the tool's definition Tool name contains 'list' and description uses 'List' verb, indicating data retrieval. Returns 'notification definitions' from sysevent_email_action table scoped to Vulnerability Response module. No modification, deletion, or execution capability described.
