The tool performs an irreversible deletion of user-created data (a Luma AI generation). Once deleted, the generation cannot be recovered. This is a classic Destructive action that cannot be undone, fitting the definition exactly.

From the tool's definition Tool name contains 'delete' and description states 'Deletes a specific Luma AI generation' — this irreversibly removes generated content.

POLICY

How to control luma_delete_generation

PolicyLayer is an MCP gateway — it sits between your AI agents and RunwayML + Luma AI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for luma_delete_generation:

policy.json

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

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

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
