Why drive_list_files needs a policy

This tool retrieves and enumerates directory contents without modifying, deleting, or executing any operations. It is a pure read operation with minimal blast radius if misused by an AI agent (worst case: exposure of file paths or metadata). Severity is low because listing files does not create, modify, or delete data and does not trigger external operations.

From the tool's definition Tool name 'drive_list_files' and description 'List files and folders in a Synology Drive path' indicate retrieval/query operations. Supports pagination, sorting, and filtering—all non-destructive read operations with no side effects.

How to control drive_list_files

PolicyLayer is an MCP gateway — it sits between your AI agents and Synology Office, and nothing reaches the server without passing your rules. This is the rule we recommend for drive_list_files:

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

drive_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 Synology Office — 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.
