Remove a snapshot. Args: vm_name: Name of the VM snapshot_name: Name of the snapshot to remove user_id: Optional user ID (admin only) Returns: Removal result
AI agents call remove_snapshot to permanently remove resources in Ludus FastMCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a snapshot is irreversible—once deleted, the snapshot cannot be recovered through standard tool interactions. This fits the Destructive category definition of 'irreversibly deletes or overwrites data, or actions that cannot be undone'.
From the tool's definition Tool name explicitly states 'remove_snapshot' and description confirms it removes a snapshot with no mention of recovery, rollback, or reversibility. The operation destructively deletes a saved VM state that cannot be restored through this tool.

Documented attack patterns abuse exactly the kind of access remove_snapshot gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ludus FastMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for remove_snapshot:
{
"version": "1",
"default": "deny",
"hide": [
"remove_snapshot"
]
}remove_snapshot disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Remove a snapshot. Args: vm_name: Name of the VM snapshot_name: Name of the snapshot to remove user_id: Optional user ID (admin only) Returns: Removal result. It is categorised as a Destructive tool in the Ludus FastMCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ludus Fast MCP server in PolicyLayer and add a rule for remove_snapshot: 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 Ludus FastMCP. Nothing to install.
remove_snapshot is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the remove_snapshot 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.
Set action: deny in the PolicyLayer policy for remove_snapshot. 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.
remove_snapshot is provided by the Ludus Fast MCP server (tjnull/ludus-fastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
