Track changes across SharePoint sites. Returns sites that have been added, modified, or deleted since the last delta query. Pass the deltaLink from a previous response to get incremental changes.
AI agents call get_sites_delta to retrieve information from Apple Shortcuts without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves change metadata from SharePoint sites without modifying or deleting data. While the sensitivity is medium due to potential exposure of organizational structure and change history, the core function is read-only enumeration of deltas. No data is created, modified, or destroyed.
From the tool's definition Tool description states it 'Returns sites that have been added, modified, or deleted' and 'track changes' — these are query/retrieval operations. The deltaLink mechanism is a standard read-only cursor pattern for incremental data fetching.
Documented attack patterns abuse exactly the kind of access get_sites_delta 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 get_sites_delta:
{
"version": "1",
"default": "deny",
"tools": {
"get_sites_delta": {}
}
}get_sites_delta is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Track changes across SharePoint sites. Returns sites that have been added, modified, or deleted since the last delta query. Pass the deltaLink from a previous response to get incremental changes. It is categorised as a Read tool in the Apple Shortcuts MCP Server, which means it retrieves data without modifying state.
Register the Apple Shortcuts MCP server in PolicyLayer and add a rule for get_sites_delta: 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.
get_sites_delta is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_sites_delta 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 get_sites_delta. 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.
get_sites_delta 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.
