## Why get_supervisor_info is rated Low

This tool retrieves read-only metadata about the Home Assistant Supervisor (version, channel, health status). It performs no modifications, does not execute code or trigger external operations, and does not delete or move data. The blast radius of misuse is minimal—an agent could only gain visibility into system state information already available to authenticated users. Classification as Read is appropriate.

From the tool's own definition: "Tool name 'get_supervisor_info' and description 'Get info about the Supervisor itself (version, channel, healthy)' indicate a query operation that retrieves status information without modifying state."

## Use case

AI agents call get_supervisor_info 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Ha Nexus Agent:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_supervisor_info": {}
  }
}
```
