AI agents call list_mysql_users to retrieve information from cPanel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves information about MySQL database users without any side effects. It does not create, modify, delete, or execute any operations—it merely enumerates existing users. This is a straightforward read operation with minimal security impact unless the returned user list exposes sensitive account enumeration, but the tool itself performs no destructive or dangerous action.
From the tool's definition Tool name 'list_mysql_users' and description 'List all MySQL database users' indicate retrieval of existing data with no modification or deletion. The verb 'list' is a classic read operation.

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 list_mysql_users:
{
"version": "1",
"default": "deny",
"tools": {
"list_mysql_users": {}
}
}list_mysql_users is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all MySQL database users. It is categorised as a Read tool in the cPanel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the cPanel MCP Server MCP server in PolicyLayer and add a rule for list_mysql_users: 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.
list_mysql_users is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_mysql_users 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 list_mysql_users. 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.
list_mysql_users 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.
