Generate a new two-factor authentication secret (returns QR code data)
AI agents use generate_2fa_config 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/modifies security credentials (2FA secret) reversibly. While it does not delete or execute external commands, it generates authentication material that alters account security state.
From the tool's definition Tool generates a new two-factor authentication secret and returns QR code data. This is a creation action that modifies the user's security configuration by establishing a new 2FA secret, which must be stored or confirmed.
Documented attack patterns abuse exactly the kind of access generate_2fa_config 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 generate_2fa_config:
{
"version": "1",
"default": "deny",
"tools": {
"generate_2fa_config": {
"limits": [
{
"counter": "generate_2fa_config_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generate_2fa_config 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.

Generate a new two-factor authentication secret (returns QR code data). 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 generate_2fa_config: 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.
generate_2fa_config 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 generate_2fa_config 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 generate_2fa_config. 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.
generate_2fa_config 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.
