AI agents call rollback to permanently remove resources in Novyx — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The server description explicitly mentions 'rollback' as a key capability, implying this tool reverts previously committed actions or state changes. Rollback operations are typically irreversible in the sense that the intermediate states are lost and the system is restored to a prior state — this can have significant side effects on shared memory, audit trails, or executed actions.
From the tool's definition Tool name 'rollback' in the context of a server that explicitly advertises 'rollback' as a core feature for governed actions and shared memory
Documented attack patterns abuse exactly the kind of access rollback gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Novyx, and nothing reaches the server without passing your rules. This is the rule we recommend for rollback:
{
"version": "1",
"default": "deny",
"hide": [
"rollback"
]
}rollback disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

rollback. It is categorised as a Destructive tool in the Novyx MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Novyx MCP server in PolicyLayer and add a rule for rollback: 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 Novyx. Nothing to install.
rollback 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 rollback 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 rollback. 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.
rollback is provided by the Novyx MCP server (novyxlabs/novyx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
