WHAT IT DOES

What labels_list does on Vikunja

AI agents call labels_list to retrieve information from Vikunja without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why labels_list is rated Low

This tool queries and returns a list of existing labels. It performs no modifications, deletions, executions, or financial operations. The blast radius of misuse is minimal—an agent could only enumerate labels it already has access to, with no ability to alter state or perform harmful actions.

From the tool's definition Tool name is 'labels_list' and description states 'List all labels the user has access to' — a retrieval operation with no side effects.
