snow_define_kpi · Serac MCP: Risk & Policy

WHAT IT DOES

What snow_define_kpi does on Serac

AI agents use snow_define_kpi to create or update resources in Serac — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Serac environment.

WHY IT NEEDS A POLICY

Why snow_define_kpi needs a policy

Defining KPIs creates new monitoring configurations or modifies existing ones in ServiceNow, which are reversible write operations. This is not a destructive action (KPIs can be edited or removed), nor does it execute arbitrary code or move money. The severity is medium because misconfigured KPIs could affect business monitoring and reporting, but the operation itself is recoverable.

From the tool's definition Tool name 'snow_define_kpi' and description 'Define Key Performance Indicators for monitoring' indicate creation or modification of KPI definitions in ServiceNow.
