Why create_tag needs a policy

This tool creates (modifies state by adding) a new tag, which is reversible—tags can be deleted or renamed. It does not execute arbitrary code, delete data irreversibly, move money, or trigger destructive workflows. The blast radius of accidental tag creation is minimal, as tags are organizational metadata.

From the tool's definition Creates a new tag in a Storyblok space via the Management API. The verb 'creates' and the phrase 'new tag' indicate data creation, which is a write operation.

How to control create_tag

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_tag:

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

create_tag 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.
