AI agents call delete_agent 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.
This tool removes an agent irreversibly with no undo mechanism stated. While the blast radius is scoped to a single agent rather than bulk deletors, deletion is inherently destructive. Severity is 'high' rather than 'critical' because impact is limited to one agent at a time and the context suggests governance/approval workflows (via sibling tools like 'approve_action') may guard its use.
From the tool's definition Tool name: 'delete_agent'. Description: 'Delete an agent.' The verb 'delete' directly indicates irreversible removal of data (an agent entity).
Documented attack patterns abuse exactly the kind of access delete_agent 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 delete_agent:
{
"version": "1",
"default": "deny",
"hide": [
"delete_agent"
]
}delete_agent disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete an agent. 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 delete_agent: 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.
delete_agent 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 delete_agent 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 delete_agent. 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.
delete_agent 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.
