WHAT IT DOES

What list_assets does on NowAIKit — ServiceNow AI Toolkit

AI agents call list_assets to retrieve information from NowAIKit — ServiceNow AI Toolkit without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_assets is rated Low

This tool queries and retrieves IT asset information from ServiceNow, which is a Read operation. Severity is medium rather than low because IT asset inventory data can reveal organizational infrastructure details (hardware, software, locations) that could inform further attacks or social engineering, even though the operation itself is non-destructive and has no side effects.

From the tool's definition Tool description states 'List IT assets with optional filtering by state, class, or assigned user' — a read operation that retrieves data without modification.
