## Why list_plugins is rated Low

This tool only retrieves and enumerates installed plugins. There are no side effects, no data modification, no code execution triggered by the tool itself, and no irreversible actions. It is a straightforward informational query fitting the 'Read' category.

From the tool's own definition: "Tool name is 'list_plugins' and description states 'List installed plugins' — a pure query operation that retrieves information about system plugins without modifying any state."

## Use case

AI agents call list_plugins to retrieve information from OPNsense MCP Server 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 OPNsense MCP Server:

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