Enable the spam box (auto-deliver spam to a separate folder)
AI agents use enable_spam_box to create or update resources in cPanel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your cPanel MCP Server environment.
This is a Write operation because it modifies email account settings and configuration (enabling/activating a feature) in a reversible manner. It does not delete data, execute arbitrary code, or trigger financial transactions. The operation creates a new email folder structure or modifies delivery rules, which is characteristic of a Write action.
From the tool's definition The tool description states 'Enable the spam box (auto-deliver spam to a separate folder)', which modifies email handling configuration by creating or enabling a separate spam folder and changing mail delivery behavior.
Documented attack patterns abuse exactly the kind of access enable_spam_box gives an agent:
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_box:
{
"version": "1",
"default": "deny",
"tools": {
"enable_spam_box": {
"limits": [
{
"counter": "enable_spam_box_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}enable_spam_box 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.

Enable the spam box (auto-deliver spam to a separate folder). 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.
Register the cPanel MCP Server MCP server in PolicyLayer and add a rule for enable_spam_box: 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.
enable_spam_box is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the enable_spam_box 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.
Set action: deny in the PolicyLayer policy for enable_spam_box. 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.
enable_spam_box 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.
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.
