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

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

## Why buckets_delete is rated Critical

This tool permanently deletes kanban buckets, which cannot be undone. Destructive operations have higher severity than Write operations. While a single bucket deletion has moderate blast radius, kanban buckets often contain tasks/work items, making accidental deletion impactful. High severity is appropriate for irreversible data loss in a task management system.

From the tool's own definition: "Tool name contains 'delete' and description states 'Delete a kanban bucket', which irreversibly removes data structures and their contents."

## Use case

AI agents call buckets_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": [
    "buckets_delete"
  ]
}
```
