Get custom metadata (SharePoint column values) for a file or folder. Returns all custom fields added by site administrators, such as Department, Status, Category, etc.
AI agents call get_file_metadata 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 and queries existing metadata from SharePoint without causing side effects, modifications, or state changes. It is a read-only operation that returns information about files/folders. While metadata about file organization could be considered informational, the tool has no capability to modify, execute, or delete anything.
From the tool's definition Tool name 'get_file_metadata' and description 'Get custom metadata (SharePoint column values) for a file or folder. Returns all custom fields...' indicates pure retrieval of metadata without modification, deletion, or execution.
Documented attack patterns abuse exactly the kind of access get_file_metadata 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_file_metadata:
{
"version": "1",
"default": "deny",
"tools": {
"get_file_metadata": {}
}
}get_file_metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Apple Shortcuts MCP server in PolicyLayer and add a rule for get_file_metadata: 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_file_metadata 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_file_metadata 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_file_metadata. 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_file_metadata 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.
