## Why labels_delete is rated Critical

This tool permanently removes labels from the Vikunja task management system. Deletion is irreversible and cannot be undone through normal operations. While the blast radius is somewhat limited to a single label entity (not the entire database), it still qualifies as Destructive because the action cannot be reversed.

From the tool's own definition: "Tool name is 'labels_delete' with description 'Delete a label'. The verb 'delete' indicates irreversible removal of data."

## Use case

AI agents call labels_delete to permanently remove resources in Vikunja, 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 Vikunja:

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