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

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

## Why props_delete_collection is rated Critical

The tool performs an irreversible deletion operation on prop collections in ProPresenter 7. Even though the blast radius is limited to presentation props rather than critical system data, deletion of collections cannot be undone and represents loss of user work. This meets the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.'

From the tool's own definition: "Tool name contains 'delete' and description states 'Delete a specific prop collection' — this is an irreversible removal of data."

## Use case

AI agents call props_delete_collection to permanently remove resources in Propresenter, 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 Propresenter:

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