Medium Risk

Why drive_move_file needs a policy

drive_move_file performs reversible modifications to file metadata and location within Synology Drive. Moving and renaming files changes their organization and accessibility but does not destroy data or create new data—it is a structural modification. This is a Write operation rather than Destructive (data remains intact and the operation can be undone by moving again) or Read (it modifies state).

From the tool's definition Tool description: 'Move or rename a file/folder in Synology Drive. Set confirm=true to execute; omit or set false for a dry-run check.' The tool modifies file/folder locations and names (move/rename operations).

POLICY

How to control drive_move_file

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_move_file:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "drive_move_file": {
      "limits": [
        {
          "counter": "drive_move_file_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

drive_move_file stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about drive_move_file

What does the drive_move_file tool do? +

Move or rename a file/folder in Synology Drive. Set confirm=true to execute; omit or set false for a dry-run check. It is categorised as a Write tool in the Synology Office MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on drive_move_file? +

Register the Synology Office MCP server in PolicyLayer and add a rule for drive_move_file: 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 Synology Office. Nothing to install.

What risk level is drive_move_file? +

drive_move_file is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit drive_move_file? +

Yes. Add a rate_limit block to the drive_move_file 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.

How do I block drive_move_file completely? +

Set action: deny in the PolicyLayer policy for drive_move_file. 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.

What MCP server provides drive_move_file? +

drive_move_file is provided by the Synology Office MCP server (vocweb/synology-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Synology Office tool call.

Start from Synology Office, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
