AI agents use enable_modsecurity 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 tool creates or modifies security configurations (enabling a WAF globally) but the change is reversible—ModSecurity can be disabled if needed. It does not execute arbitrary code, delete data, or move money. While it affects security posture broadly, the primary action is configuration Write rather than Execute, since it applies a predefined security module rather than running dynamic code.
From the tool's definition Tool name 'enable_modsecurity' and description 'Enable ModSecurity (WAF) for all domains' indicate configuration modification. ModSecurity is a Web Application Firewall that when enabled modifies server security settings across all domains.
Documented attack patterns abuse exactly the kind of access enable_modsecurity 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_modsecurity:
{
"version": "1",
"default": "deny",
"tools": {
"enable_modsecurity": {
"limits": [
{
"counter": "enable_modsecurity_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}enable_modsecurity 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.
Free to start. No card required.
Enable ModSecurity (WAF) for all domains. 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_modsecurity: 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_modsecurity 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_modsecurity 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_modsecurity. 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_modsecurity 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.
Free to start. No card required.
