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

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

  "method": "tools/call",
  "params": {
    "name": "zotero_delete_annotation",
    "arguments": {}
  }
}
```

## Why zotero_delete_annotation is rated Critical

Deletion operations are irreversible and cannot be undone. Even though annotations are typically auxiliary metadata rather than primary research data, their loss is permanent and could disrupt research workflows, note-taking, or citation analysis.

From the tool's own definition: "Tool name explicitly contains 'delete' combined with 'annotation', indicating irreversible removal of data. The verb 'delete' is a canonical destructive operation. Tool description is empty, which slightly reduces confidence, but the name alone is unambiguous."

## Use case

AI agents call zotero_delete_annotation to permanently remove resources in Zotero MCP, 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 Zotero MCP:

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