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

```json
{
  "jsonrpc": "2.0",
  "id": 1,

## Why delete_application_auth_method is rated Critical

The tool permanently removes an authentication method, which cannot be undone. Deleting authentication credentials or methods could break application access, disable security controls, or cause service outages. This fits the Destructive category (irreversibly deletes data) rather than Write (reversible modifications).

From the tool's own definition: "Tool name includes 'delete' and description states 'Delete an authentication method from an application.' This is an irreversible deletion operation."

## Use case

AI agents call delete_application_auth_method to permanently remove resources in CyberArk Privilege Cloud MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)
