This tool permanently removes a field plugin configuration from the Storyblok space, which cannot be undone and affects the content structure. Deletion of field plugins is irreversible and could break dependent content schemas or workflows. While not as severe as catastrophic data loss affecting all stories, the irreversible nature and potential for breaking system dependencies justify a 'high' severity rating.

From the tool's definition The tool name is 'delete_field_plugin' and the description states it 'Deletes a field plugin by its ID.' The verb 'deletes' indicates irreversible removal of data.

POLICY

How to control delete_field_plugin

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_field_plugin:

policy.json

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

delete_field_plugin 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.
