THE RISK

Critical Risk

Why snapshot_delete needs a policy

The tool irreversibly deletes a saved snapshot, freeing disk space and permanently removing the saved state. This is an unrecoverable action — once deleted, the snapshot cannot be restored. High severity because it could wipe environment state an agent or user depends on.

From the tool's definition Delete a saved snapshot by label...the next vm_create with this label will start fresh

Documented attack patterns abuse exactly the kind of access snapshot_delete gives an agent:

POLICY

How to control snapshot_delete

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "snapshot_delete"
  ]
}

snapshot_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Taw Computer — 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 snapshot_delete

What does the snapshot_delete tool do? +

Delete a saved snapshot by label. This frees disk space and means the next vm_create with this label will start fresh. It is categorised as a Destructive tool in the Taw Computer MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on snapshot_delete? +

Register the Taw Computer MCP server in PolicyLayer and add a rule for snapshot_delete: 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 Taw Computer. Nothing to install.

What risk level is snapshot_delete? +

snapshot_delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit snapshot_delete? +

Yes. Add a rate_limit block to the snapshot_delete 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 snapshot_delete completely? +

Set action: deny in the PolicyLayer policy for snapshot_delete. 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 snapshot_delete? +

snapshot_delete is provided by the Taw Computer MCP server (tawgroup/taw-computer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Taw Computer tool call.

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