WHAT IT DOES

What set_file_tags does on AIquila — Nextcloud MCP Server

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

RISK

Why set_file_tags is rated Medium

This tool modifies file metadata (tags) in a reversible manner. Tags can be added, replaced, or cleared without deleting underlying file content. It qualifies as Write rather than Read (retrieves data) or Destructive (irreversible deletion). The reversibility and limited scope (metadata only) justify medium severity—an agent could disrupt organization/workflows but not cause data loss or financial harm.

From the tool's definition Tool sets/replaces personal tags on files or folders. Description explicitly states: 'Replaces all existing personal tags' and 'Use an empty array to clear all tags.' This is a modification operation that alters metadata.
