Why opus_upload_video needs a policy

The tool creates new resources (uploaded video asset and clipping project) in OpusClip, which are reversible write operations. While it involves external service integration via Apple Shortcuts CLI, it does not execute arbitrary code, delete data, or move money.

From the tool's definition Tool performs 'upload' and 'create' operations: uploads a video file to OpusClip and creates a clipping project. These are write operations that modify state in an external service.

POLICY

How to control opus_upload_video

PolicyLayer is an MCP gateway — it sits between your AI agents and Apple Shortcuts, and nothing reaches the server without passing your rules. This is the rule we recommend for opus_upload_video:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "opus_upload_video": {
      "limits": [
        {
          "counter": "opus_upload_video_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

opus_upload_video stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Apple Shortcuts — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
