## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "delete_custom_application",
    "arguments": {}

}
```

## Why delete_custom_application is rated Critical

The tool performs a delete operation on a custom application object in FortiManager. Deletion is irreversible and cannot be undone without administrative restoration or backups. This is the defining characteristic of the Destructive category.

From the tool's own definition: "Tool name 'delete_custom_application' and description 'Delete a custom application' explicitly use the word 'Delete', which denotes irreversible removal of data."

## Use case

AI agents call delete_custom_application to permanently remove resources in Fortimanager, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Fortimanager:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_custom_application"
  ]
}
```
