Create a new clip collection to organise your clips.
AI agents use opus_create_collection 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 tool creates a new collection for organizing clips. This is a reversible write operation (the collection can be deleted, modified, or abandoned). It has minimal blast radius—creating unwanted collections is low-impact and easily corrected. No financial, destructive, or execute characteristics are evident. Confidence is high due to the clear 'Create' verb and low-severity nature of organizing clips.
From the tool's definition The tool description explicitly states it will 'Create a new clip collection', which is a write operation that creates new data structures.
Documented attack patterns abuse exactly the kind of access opus_create_collection 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_collection:
{
"version": "1",
"default": "deny",
"tools": {
"opus_create_collection": {
"limits": [
{
"counter": "opus_create_collection_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}opus_create_collection 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.
