```json

  "jsonrpc": "2.0",

## Why get_config is rated Low

This tool retrieves configuration data from Home Assistant without creating, modifying, or deleting anything. While the retrieved config data could be sensitive (API keys, user settings, network details), the action itself is read-only.

From the tool's own definition: "Tool description states 'Get HA config via WebSocket' — the verb 'Get' indicates retrieval without modification. Home Assistant configuration may contain sensitive settings, credentials, or system details."

## Use case

AI agents call get_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.

## 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_config": {}
  }
}
```
