THE RISK

Medium Risk

Why enable_dkim needs a policy

This tool modifies email authentication infrastructure by enabling DKIM, which requires creating or updating DNS records and email server configuration. This is a Write operation because it creates or modifies system configuration reversibly. The severity is medium because misconfiguration could impact email deliverability for the domain, but the change can be disabled/undone.

From the tool's definition Tool description states "Enable DKIM (DomainKeys Identified Mail) for a domain". DKIM is a cryptographic authentication mechanism that modifies DNS records and email configuration.

POLICY

How to control enable_dkim

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

policy.json

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

enable_dkim 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about enable_dkim

What does the enable_dkim tool do? +

Enable DKIM (DomainKeys Identified Mail) for a domain. It is categorised as a Write tool in the cPanel MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on enable_dkim? +

Register the cPanel MCP Server MCP server in PolicyLayer and add a rule for enable_dkim: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches cPanel MCP Server. Nothing to install.

What risk level is enable_dkim? +

enable_dkim is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit enable_dkim? +

Yes. Add a rate_limit block to the enable_dkim rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block enable_dkim completely? +

Set action: deny in the PolicyLayer policy for enable_dkim. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides enable_dkim? +

enable_dkim is provided by the cPanel MCP Server MCP server (0xhayd3n/cpanel-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every cPanel MCP Server tool call.

Start from cPanel MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
