List email notification rules
AI agents call notification_list to retrieve information from ServiceNow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing notification rules from ServiceNow without creating, modifying, or deleting any data. It is purely informational and carries minimal risk if misused by an AI agent—the worst outcome would be unauthorized visibility of notification configuration, which is a read-only concern.
From the tool's definition Tool name 'notification_list' and description 'List email notification rules' indicate a retrieval operation with no data modification.
