## Why get_preview_result is rated Low

The 'get_preview_result' function follows standard read operation patterns (get_*) and logically would retrieve pre-computed or simulated results without modifying system state. In the context of FortiManager, preview operations typically show what would happen before actual changes are applied. This is consistent with Read category behavior.

From the tool's own definition: "Tool name 'get_preview_result' indicates a retrieval operation to fetch results of a preview (likely a dry-run or simulation). No description provided, but naming convention suggests read-only data retrieval."

## Use case

AI agents call get_preview_result to retrieve information from FortiManager 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 FortiManager MCP Server:

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