THE RISK

Medium Risk

Why publish_release needs a policy

Publishing a release modifies the live state of published content in Storyblok CMS, making it a Write operation that affects production content visibility and availability. This is reversible (can unpublish or create new releases) rather than destructive. Severity is high due to potential blast radius of publishing incorrect or incomplete content to live audiences.

From the tool's definition Tool name 'publish_release' indicates publishing/releasing content in a CMS context. Sibling tools include 'add_story_to_release' and 'backup_space', establishing this as a content management server where releases represent versioned content deployments.

POLICY

How to control publish_release

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 publish_release:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "publish_release": {
      "limits": [
        {
          "counter": "publish_release_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

publish_release 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.

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.
