MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Truenas Ws tools

Destructive · High delete_app This tool permanently removes an installed app, which cannot be undone without reinstalling. Destructive · Critical delete_dataset Deleting a dataset permanently removes data and cannot be undone. Destructive · High delete_nfs_export Deleting an NFS export is a destructive action that cannot be undone and removes network file system access configuration. Destructive · High delete_smb_share Deleting an SMB share removes a network resource configuration that cannot be automatically recovered without recreation.

27 of Truenas Ws's 59 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Truenas Ws

PolicyLayer is an MCP gateway — it sits between your AI agents and Truenas Ws, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "delete_app": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "clone_snapshot": {
    "limits": [
      {
        "counter": "clone_snapshot_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "check_updates": {
    "limits": [
      {
        "counter": "check_updates_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Truenas Ws — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Truenas Ws

Can an AI agent delete data through the Truenas Ws MCP server? +

Yes. The Truenas Ws server exposes 7 destructive tools including delete_app, delete_dataset, delete_nfs_export. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Truenas Ws? +

The Truenas Ws server has 10 write tools including clone_snapshot, create_dataset, create_nfs_export. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Truenas Ws.

How many tools does the Truenas Ws MCP server expose? +

59 tools across 4 categories: Destructive, Execute, Read, Write. 32 are read-only. 27 can modify, create, or delete data.

How do I enforce a policy on Truenas Ws? +

Register the Truenas Ws MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Truenas Ws tool call.

Deterministic rules across all 59 Truenas Ws tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
