AI agents use create_ftp_account 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.
Creating an FTP account is a Write operation—it modifies the hosting account configuration by adding a new user with credentials and filesystem access. While reversible (the account can be deleted), it creates persistent system state. Severity is high because an AI misusing this could create backdoor accounts, compromise server access control, or enable unauthorized data exfiltration through FTP.
From the tool's definition Tool name 'create_ftp_account' and description 'Create a new FTP account' indicate irreversible creation of a new account with persistent access credentials.
Documented attack patterns abuse exactly the kind of access create_ftp_account 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 create_ftp_account:
{
"version": "1",
"default": "deny",
"tools": {
"create_ftp_account": {
"limits": [
{
"counter": "create_ftp_account_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_ftp_account 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 new FTP account. 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 create_ftp_account: 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.
create_ftp_account 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 create_ftp_account 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 create_ftp_account. 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.
create_ftp_account 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.
