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

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

## Why delete_cached_model is rated Critical

This tool permanently deletes cached 3D model files and their metadata without recovery option. While the impact is scoped to cached models (not active print jobs or system files), deletion of design files represents irreversible data loss. In a 3D printing workflow context, cached models may include expensive design iterations, custom configurations, or user-generated content.

From the tool's own definition: "Tool name explicitly states 'delete_cached_model' and description confirms 'Remove a model from the local cache (file and metadata)' — irreversible deletion of data."

## Use case

AI agents call delete_cached_model to permanently remove resources in Kiln, 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 Kiln:

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