WHAT IT DOES

What reload_zones does on Ha Nexus Agent

AI agents invoke reload_zones to trigger actions in Ha Nexus Agent. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why reload_zones is rated High

This tool triggers an external service call (`zone.reload`) that reloads zone configuration from YAML files. It executes an operation in Home Assistant rather than just reading data or destructively deleting anything. Misuse could disrupt zone-based automations and presence detection across the smart home.

RECOMMENDED RULE

The rule that runs reload_zones 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 reload_zones, this is the rule to start with:

reload_zones Rate-limited

reload_zones stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Ha Nexus Agent, apply this rule, and every reload_zones call is checked against it from then on.
