Delete an eval baseline.

How to control eval_baseline_delete ↓

AI agents call eval_baseline_delete 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.

Critical Risk

This tool performs an irreversible deletion operation on an eval baseline. Destructive operations carry higher severity than Write operations because they cannot be undone. The high confidence reflects the unambiguous destructive nature of the delete action.

From the tool's definition Tool name 'eval_baseline_delete' combined with description 'Delete an eval baseline' explicitly indicates irreversible deletion of data. The verb 'delete' is a clear destructive operation.

Documented attack patterns abuse exactly the kind of access eval_baseline_delete 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 eval_baseline_delete:

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "eval_baseline_delete"
  ]
}

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

  1. Create a free account and register Novyx — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
