Why create_cdn_zone needs a policy

Creating a CDN zone is a reversible write operation that adds a new resource to the infrastructure. While not destructive (can be deleted) or immediately dangerous, misconfiguration could affect traffic routing or expose services to the public internet, justifying medium severity. Confidence is moderate due to empty description; however, 'create_' operations universally map to Write category.

From the tool's definition Tool name 'create_cdn_zone' indicates creation of a CDN zone resource. The verb 'create' signals data modification. The description is empty, limiting precision.

How to control create_cdn_zone

PolicyLayer is an MCP gateway — it sits between your AI agents and Vultr MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_cdn_zone:

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

create_cdn_zone 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 Vultr MCP — 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.
