Copy a file or folder to a new location in a SharePoint document library.
AI agents use copy_library_item 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 new data (a copy of a file or folder) in SharePoint, which constitutes a Write operation. It is reversible (the copy can be deleted), so it does not qualify as Destructive. The severity is medium because unauthorized copying could expose sensitive documents or violate access controls, but the blast radius is limited by SharePoint permissions and the reversibility of the action.
From the tool's definition Tool description explicitly states 'Copy a file or folder to a new location in a SharePoint document library.' The action of copying creates duplicate data in a new location, which is a reversible modification operation.
Documented attack patterns abuse exactly the kind of access copy_library_item 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 copy_library_item:
{
"version": "1",
"default": "deny",
"tools": {
"copy_library_item": {
"limits": [
{
"counter": "copy_library_item_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}copy_library_item 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.

Copy a file or folder to a new location in a SharePoint document library. 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 copy_library_item: 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.
copy_library_item 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 copy_library_item 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 copy_library_item. 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.
copy_library_item 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.
