Listet alle Tags.
AI agents call uptime_list_tags to retrieve information from Uptime Kuma without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing tags from the Uptime Kuma system. It performs a read-only query with no capability to modify, delete, or execute operations. The blast radius of misuse is minimal—an AI agent could only enumerate tags, which poses no security or operational risk.
From the tool's definition Tool name 'uptime_list_tags' and description 'Listet alle Tags' (German: 'Lists all tags') indicate a query/listing operation with no side effects.
