List all personal labels in the user's Todoist account.
AI agents call list_labels to retrieve information from Todoist MCP Helper without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns existing labels from the user's Todoist account without creating, modifying, or deleting any data. It is a pure read operation with no destructive or harmful side effects. The blast radius is minimal as it only exposes label metadata that the user would already have access to within their own account.
From the tool's definition Tool name is 'list_labels' and description states 'List all personal labels' - a retrieval operation with no modification or side effects.
