AI agents use change_ftp_password 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 modifies (writes) FTP account credentials, which is a reversible action. While credentials are sensitive, the operation itself is not destructive (the account persists), not financial, and not executing arbitrary code. The high severity reflects that compromised FTP credentials could grant broad file system access to a hosting account, making this a high-impact write operation if misused by an AI agent.
From the tool's definition Tool name 'change_ftp_password' and description 'Change an FTP account password' indicate modification of credentials. This is a reversible write operation that alters authentication data for FTP accounts.
Documented attack patterns abuse exactly the kind of access change_ftp_password 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 change_ftp_password:
{
"version": "1",
"default": "deny",
"tools": {
"change_ftp_password": {
"limits": [
{
"counter": "change_ftp_password_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}change_ftp_password 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.
Change an FTP account password. 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 change_ftp_password: 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.
change_ftp_password 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 change_ftp_password 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 change_ftp_password. 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.
change_ftp_password 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.
