## Why stage_hide_message is rated Medium

This tool hides a stage message in ProPresenter 7, which is a reversible UI state change (the message can be shown again). It modifies display state but does not delete data or execute arbitrary code, making Write the appropriate category. Severity is low as it only affects presentation display.

From the tool's own definition: "Hide the current stage message"

## Use case

AI agents use stage_hide_message to create or update resources in Propresenter, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Propresenter environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Propresenter:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "stage_hide_message": {
      "limits": [
        {
          "counter": "stage_hide_message_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
