AI agents call ops_list_uk_maintenance to retrieve information from Ops without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of existing maintenance windows from Uptime Kuma. It performs no state changes, does not execute code or external operations, and does not involve financial transactions or irreversible deletions. It is a pure read operation with minimal blast radius if misused—at worst, an AI agent would retrieve information it shouldn't see, not cause any operational damage.
From the tool's definition Tool name 'ops_list_uk_maintenance' and description 'List all Uptime Kuma maintenance windows' indicate a retrieval operation with no modification or side effects.
