WHAT IT DOES

What remove_energy_source does on Ha Nexus Agent

AI agents call remove_energy_source to permanently remove resources in Ha Nexus Agent, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why remove_energy_source is rated Critical

This tool permanently deletes energy source configuration and related grid flow entries from a Home Assistant energy management system. The operation cannot be undone without manual reconfiguration, making it destructive rather than merely a write operation. In a smart home context, removing energy sources affects billing calculations, monitoring, and automation logic.

From the tool's definition remove_energy_source: 'Remove an energy source' and 'strips matching grid flow_from entries' — uses destructive verb 'remove' and 'strips', indicating irreversible deletion of configuration data

RECOMMENDED RULE

The rule that runs remove_energy_source safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ha Nexus Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For remove_energy_source, this is the rule to start with:

remove_energy_source Hidden

remove_energy_source is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
