Delete a Home Assistant entity
AI agents call tools-entities-delete to permanently remove resources in Home Assistant MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion operation on Home Assistant entities. This falls squarely into the Destructive category as it permanently removes data that cannot be undone through normal UI operations. Severity is high because misconfiguration or unintended deletion could disable critical smart home automations, sensors, or devices, affecting home automation and potentially home security/safety systems.
From the tool's definition Tool name explicitly states 'delete' and description confirms 'Delete a Home Assistant entity'. This irreversibly removes data/configuration from a smart home system.
