## Why panel_check_installed is rated Low

This is a read-only operation that checks the state of installed components. It has no side effects, does not execute code, does not modify data, and does not delete anything. The 'check' verb combined with the passive description confirms it is a retrieval/query tool with minimal blast radius if misused by an agent.

From the tool's own definition: "Tool name 'panel_check_installed' and description 'Check if essential components are installed' indicate a query/inspection operation that retrieves status information about installed components without modifying anything."

## Use case

AI agents call panel_check_installed to retrieve information from Aapanel 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 Aapanel:

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