AI agents use rename_api_token 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.
The tool modifies an existing API token by changing its name/label. This is a Write operation (reversible change to data). Severity is medium because renaming an API token has limited blast radius—it affects the token's human-readable identifier but typically does not impact the token's functionality or grant the AI new permissions. However, confusion from renaming could lead to operational errors.
From the tool's definition Tool is named "rename_api_token" and described as "Rename an existing API token". Renaming is a reversible modification operation that updates metadata/properties of an existing resource without deleting it or executing arbitrary code.
Documented attack patterns abuse exactly the kind of access rename_api_token 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 rename_api_token:
{
"version": "1",
"default": "deny",
"tools": {
"rename_api_token": {
"limits": [
{
"counter": "rename_api_token_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}rename_api_token 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.

Rename an existing API token. 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 rename_api_token: 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.
rename_api_token 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 rename_api_token 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 rename_api_token. 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.
rename_api_token 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.
