List all labels/tags in the inventory.
AI agents call homebox_list_labels to retrieve information from Homebox MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves label/tag information from the inventory system without creating, modifying, deleting, or executing any operations. It has no side effects and presents minimal risk if misused by an AI agent, as it only exposes existing categorization metadata. The low severity reflects that exposure of label names poses minimal security or operational risk.
From the tool's definition Tool name 'list_labels' and description 'List all labels/tags in the inventory' indicates data retrieval with no modification. The verb 'list' is explicitly a Read operation.
