Create a new OpusClip clipping project from a publicly importable long-form video URL.
AI agents use opus_create_project to create or update resources in Apple Shortcuts — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Apple Shortcuts environment.
This is a Write operation because it creates new data (a clipping project) in an external system (OpusClip) with reversible effects (projects can be deleted). It does not execute arbitrary code, delete data irreversibly, or move funds.
From the tool's definition Tool description states "Create a new OpusClip clipping project" which is a create operation that adds a new resource. The tool takes a video URL as input and creates a persistent project object in OpusClip's system.
Documented attack patterns abuse exactly the kind of access opus_create_project gives an agent:
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_create_project:
{
"version": "1",
"default": "deny",
"tools": {
"opus_create_project": {
"limits": [
{
"counter": "opus_create_project_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}opus_create_project 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 new OpusClip clipping project from a publicly importable long-form video URL. It is categorised as a Write tool in the Apple Shortcuts MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Apple Shortcuts MCP server in PolicyLayer and add a rule for opus_create_project: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apple Shortcuts. Nothing to install.
opus_create_project is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the opus_create_project rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for opus_create_project. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
opus_create_project is provided by the Apple Shortcuts MCP server (@mindstone/mcp-server-apple-shortcuts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Apple Shortcuts, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
