List user subscriptions to notifications (who has opted in/out)
AI agents call list_notification_subscriptions 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 enumerates notification subscription preferences for users. It performs a read-only query with no capability to modify, delete, or execute operations. The blast radius if misused is low—an AI agent could retrieve subscription metadata but cannot alter configurations, trigger notifications, or perform destructive actions.
From the tool's definition Tool name 'list_notification_subscriptions' and description 'List user subscriptions to notifications (who has opted in/out)' indicate a query operation that retrieves existing data without modification or side effects.
