## Why props_clear is rated Critical

This tool removes data (a prop) from active display in a presentation context. While potentially recoverable from saved files, the action itself on the active presentation state is destructive—it eliminates the prop's visibility and state without reversal through the tool's own mechanism.

From the tool's own definition: "Tool name is 'props_clear' and description states 'Clear a specific prop from display'. The verb 'clear' in the context of presentation software means to remove or delete a prop from the current display, which is an irreversible action that cannot be undone…"

## Use case

AI agents call props_clear 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_clear"
  ]
}
```
