THE RISK

Critical Risk

Why delete_preset needs a policy

Deletion operations are irreversible and cannot be undone without manual restoration or backups. While the blast radius is limited to a single preset configuration (not affecting live content or financial systems), the destructive nature and the presence of other destructive tools in the sibling list (bulk_delete_stories, bulk_restore_assets) confirms this is a Destructive action.

From the tool's definition Tool name is 'delete_preset' and description states it 'Deletes a preset from a Storyblok space'. The verb 'deletes' indicates irreversible removal of data.

POLICY

How to control delete_preset

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

policy.json

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

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

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