WHAT IT DOES

What list_system_tags does on AIquila — Nextcloud MCP Server

AI agents call list_system_tags to retrieve information from AIquila — Nextcloud MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_system_tags is rated Low

This tool performs a read-only operation to enumerate and display existing system tags and their metadata. There are no side effects, data modification, deletion, or external state changes. It is purely informational, used to help an agent discover available tags before taking other actions. The blast radius of misuse is minimal—an agent could only access tag information already present in the system.

From the tool's definition Tool description states 'List all available system tags' — a query operation that retrieves data without modification. The phrase 'find tag IDs' confirms it is a lookup/discovery function.
