THE RISK

Why delete_approval needs a policy

This tool performs an irreversible deletion operation on approval records within a Storyblok space. Deletions cannot be undone and represent data loss. While the blast radius is somewhat limited compared to deleting all stories or spaces, the irreversible nature and potential workflow disruption (removing content approvals could bypass editorial safeguards) justifies the 'Destructive' category and 'high' severity.

From the tool's definition Tool name 'delete_approval' and description 'Deletes an approval from a specified Storyblok space' explicitly use the verb 'deletes', which indicates irreversible removal of data.

POLICY

How to control delete_approval

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_approval:

policy.json

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

delete_approval 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.
