WHAT IT DOES

What ops_create_uk_maintenance does on Ops

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

WHY IT NEEDS A POLICY

Why ops_create_uk_maintenance needs a policy

Creating a maintenance window modifies system state by scheduling downtime, which affects monitoring and alerting behavior. While reversible (can be ended), it has significant operational impact—an AI agent misusing this could incorrectly mark services as under maintenance, suppressing alerts and misleading stakeholders about service health. This warrants high severity despite being non-destructive.

From the tool's definition Tool name and description: 'Create a maintenance window in Uptime Kuma' — the verb 'create' indicates data creation. This is reversible via ops_end_uk_maintenance (sibling tool), confirming Write category.
