WHAT IT DOES

What get_ha_config does on Ha Nexus Agent

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

RISK

Why get_ha_config is rated Low

This is a read-only query that retrieves system configuration metadata. It has no side effects, does not execute code or commands, does not modify data, and does not perform financial operations. While the configuration data could theoretically inform a subsequent attack, the tool itself is purely informational retrieval.

From the tool's definition Tool name 'get_ha_config' and description state it 'Get current Home Assistant configuration' — a retrieval operation with no modification, deletion, or execution of commands. Returns metadata about configuration state (location, units, version, components).
