WHAT IT DOES

What get_business_rule does on NowAIKit — ServiceNow AI Toolkit

AI agents call get_business_rule 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 get_business_rule is rated Low

This is a Read operation: it retrieves data (business rule details and scripts) from ServiceNow without side effects. However, the severity is elevated to medium rather than low because business rule scripts may contain sensitive logic, credentials, or system configuration details that could inform an attack vector or lead to privilege escalation if misused by a compromised agent.

From the tool's definition Tool name is 'get_business_rule' and description states 'Get full details and script body of a business rule' — this retrieves and queries existing configuration data without modifying or executing it.
