Why list_files needs a policy

This tool retrieves and queries file/folder metadata from OneDrive storage without creating, modifying, deleting, or executing anything. It is a straightforward read operation with minimal blast radius—an AI agent could at worst enumerate OneDrive contents, but cannot alter data or trigger external operations.

From the tool's definition Tool description explicitly states 'List files and folders in OneDrive' with no modification, deletion, or execution capability. The verb 'list' is a read-only operation that retrieves directory contents without side effects.

How to control list_files

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_files:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_files": {}
  }
}

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

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