change_ftp_quota

THE RISK

Medium Risk

Why change_ftp_quota needs a policy

This tool modifies FTP account parameters (quota limits) rather than creating/deleting accounts or executing arbitrary commands. Changes to quotas are reversible—the quota can be adjusted again to previous values. The blast radius is medium because misconfiguration could disrupt user access or storage but does not destroy data or execute code.

From the tool's definition Tool name 'change_ftp_quota' and description 'Change an FTP account' indicate modification of existing FTP account settings, a reversible operation on hosting account configuration.

POLICY

How to control change_ftp_quota

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_quota:

policy.json

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

change_ftp_quota 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.
