List SharePoint lists in a site (task lists, custom lists, tracking sheets, etc.). Does not include document libraries — use list_site_document_libraries for those.
AI agents call list_site_lists 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.
The tool retrieves information about SharePoint lists within a site. It performs no data modification, deletion, code execution, or financial operations. The blast radius of misuse is minimal — an attacker could enumerate SharePoint structure but cannot modify, delete, or execute anything. This is a standard read/query operation.
From the tool's definition Tool description explicitly states 'List SharePoint lists in a site' — a query/retrieval operation with no modification, deletion, or execution of code.
Documented attack patterns abuse exactly the kind of access list_site_lists 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 list_site_lists:
{
"version": "1",
"default": "deny",
"tools": {
"list_site_lists": {}
}
}list_site_lists is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List SharePoint lists in a site (task lists, custom lists, tracking sheets, etc.). Does not include document libraries — use list_site_document_libraries for those. 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 list_site_lists: 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.
list_site_lists 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 list_site_lists 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 list_site_lists. 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.
list_site_lists 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.
