snow_change_manage · Serac MCP: Risk & Policy

WHAT IT DOES

What snow_change_manage does on Serac

AI agents invoke snow_change_manage to trigger actions in Serac. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why snow_change_manage needs a policy

This tool performs multiple operations in ServiceNow's change management system: creating change records, updating their state, approving changes, creating tasks, and scheduling CAB meetings. These are not simple writes — 'approve' and 'update_state' trigger downstream workflows and external operations (e.g., CAB scheduling, approval chains).

From the tool's definition Unified change management (create, update_state, approve, create_task, schedule_cab)
