THE RISK

Low Risk

Why get_library_file needs a policy

This tool retrieves metadata about files or folders in SharePoint—a read-only operation with no capacity to modify, delete, or execute code. The blast radius is minimal: at worst, an agent could enumerate file metadata it already has access to. Classified as Read with low severity.

From the tool's definition Tool description states 'Get metadata for a specific file or folder in a SharePoint document library.' The verb 'Get metadata' clearly indicates retrieval without modification. No side effects or state changes are implied.

POLICY

How to control get_library_file

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_library_file:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_library_file": {}
  }
}

get_library_file is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Apple Shortcuts — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
