Why create_tag_and_add_to_story needs a policy

From the tool's definition Tool name 'create_tag_and_add_to_story' indicates creation and modification of metadata (tags) associated with story content. The 'create' and 'add' verbs suggest write operations that generate new data structures and modify existing stories.

POLICY

How to control create_tag_and_add_to_story

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_and_add_to_story:

policy.json

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

create_tag_and_add_to_story 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.
