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

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

```

## Why delete_announcement is rated Critical

This tool permanently removes data (an announcement) and cannot be undone. Even though the blast radius is limited to announcements rather than critical user data, the irreversible nature of deletion places it in the Destructive category. Severity is high because an AI agent with admin privileges could maliciously delete all announcements, disrupting organization-wide communications.

From the tool's own definition: "Tool name is 'delete_announcement' and description states 'Delete an announcement by its ID.' The verb 'Delete' combined with the action of removing an announcement irreversibly indicates destructive capability."

Risk signals: Admin/system-level operation

## Use case

AI agents call delete_announcement to permanently remove resources in AIquila — Nextcloud MCP Server, 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 AIquila — Nextcloud MCP Server:

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