POLICY

How to control enable_spam_assassin

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_spam_assassin:

policy.json

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

enable_spam_assassin 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 cPanel 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.
