Why create_comment needs a policy

Creating a comment in a content management system like Storyblok is a write operation that modifies data (adds a comment record) but is reversible via deletion. While the description is empty, the tool name clearly indicates comment creation. Severity is medium because misuse could spam or create misleading comments in collaborative workflows, but the impact is limited in scope and reversible.

From the tool's definition Tool name 'create_comment' indicates creation of a comment object; sibling tools like 'bulk_delete_stories' and 'add_webhook' show this server manages Storyblok content and operations; empty description reduces specificity but creation of comments is a…

POLICY

How to control create_comment

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_comment:

policy.json

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

create_comment 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.
