## Facts

- Tool: `config_set_username`
- Server: Aapanel (`nipunanirmal/aapanel-mcp`) — https://policylayer.com/tools/aapanel-mcp.md
- Homepage: https://github.com/nipunanirmal/aapanel-mcp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "config_set_username",
    "arguments": {}
  }
}
```

## Why config_set_username is rated Medium

This tool modifies a critical authentication credential (admin username) reversibly, making it Write category. Severity is high because compromising or changing admin credentials grants unauthorized control over the entire aaPanel system and all hosted services. An AI agent with this capability could lock out legitimate administrators or create backdoor access.

From the tool's own definition: "Tool description states 'Change the panel admin username' — this modifies an existing administrative credential."

Risk signals: Admin/system-level operation

## Use case

AI agents use config_set_username to create or update resources in Aapanel, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aapanel environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Aapanel:

```json

  "version": "1",
  "default": "deny",
  "tools": {
    "config_set_username": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
