Medium Risk

Why create_preset needs a policy

Creating a preset is a reversible write action that modifies the configuration state of a Storyblok space. While it creates new data, presets can be edited or deleted, making this a Write rather than Destructive action. The severity is medium because misuse could clutter the space with unwanted presets or interfere with content management workflows, but the impact is limited in scope and reversible.

From the tool's definition Tool description states 'Creates a new preset in a Storyblok space via the Management API.' The verb 'creates' indicates data creation, which is a reversible write operation.

How to control create_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 create_preset:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_preset": {
      "limits": [
        {
          "counter": "create_preset_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_preset stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Storyblok MCP Server — 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.
