Create a sharing link for a file or folder in a SharePoint document library. Returns a URL that can be shared with others.
AI agents use create_sharing_link 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 sharing links, which is a write operation that modifies SharePoint state by adding new sharing configurations. It is reversible (links can be revoked) and does not delete data, execute arbitrary code, move money, or irreversibly destroy information.
From the tool's definition Tool description states it 'Create[s] a sharing link' which generates a new resource (a URL) in SharePoint, modifying access permissions and creating reversible metadata.
Documented attack patterns abuse exactly the kind of access create_sharing_link 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 create_sharing_link:
{
"version": "1",
"default": "deny",
"tools": {
"create_sharing_link": {
"limits": [
{
"counter": "create_sharing_link_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_sharing_link 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 sharing link for a file or folder in a SharePoint document library. Returns a URL that can be shared with others. 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 create_sharing_link: 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.
create_sharing_link 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 create_sharing_link 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 create_sharing_link. 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.
create_sharing_link 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.
