Récupère la liste de toutes les entités Home Assistant avec leurs états
AI agents call get_entities to retrieve information from Home Assistant MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves entity data and state information from a smart home system. While it is a read-only operation with no side effects, the severity is elevated to medium because the data returned could reveal sensitive information about the home environment (device types, states, presence/absence patterns, device locations), which could be exploited for security or privacy purposes if misused by an untrusted agent.
From the tool's definition Tool description states 'Récupère la liste de toutes les entités Home Assistant avec leurs états' (retrieves the list of all Home Assistant entities with their states). The action is purely retrieval with no modification, deletion, or execution.
