What search_devices does on Ha Nexus Agent

AI agents call search_devices 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.

Why search_devices is rated Low

This is a retrieval-only operation that searches existing data and returns results with no side effects. It does not create, modify, delete, or execute any actions on the smart home system. The search operation is inherently non-destructive and poses minimal security risk, though it could potentially leak information about devices in a system if accessed by an unauthorized party.

From the tool's definition The tool description explicitly states it performs 'Fuzzy search devices' without any modification, creation, deletion, or execution capabilities. It only retrieves and queries device information by name, user-assigned name, manufacturer, and model.

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

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_devices": {}
  }
}
