Block an IP address or range

Agent View of the PolicyLayer registry record for `block_ip`. HTML page: https://policylayer.com/tools/0xhayd3n-cpanel-mcp-server/block-ip

## Facts

- Tool: `block_ip`
- Server: cPanel MCP Server (`0xhayd3n/cpanel-mcp-server`) — https://policylayer.com/tools/0xhayd3n-cpanel-mcp-server.md
- Homepage: https://github.com/0xHayd3n/cPanel-MCP-Server
- 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": "block_ip",
    "arguments": {}
  }
}
```

## Why block_ip is rated Medium

Blocking an IP address modifies firewall/access control rules to prevent access. While this is a write/configuration change, it is potentially reversible (IPs can be unblocked), so it falls under Write rather than Destructive. However, it carries high severity because misuse by an AI agent could block legitimate users, critical services, or even the server's own management IP, causing significant access disruption.

From the tool's own definition: "Block an IP address or range"

## Use case

AI agents use block_ip 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.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "block_ip": {
      "limits": [
        {
          "counter": "block_ip_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
