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

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

## Why run_mapcidr is rated High

MapCIDR manipulates and expands CIDR ranges, typically used in reconnaissance workflows. While ostensibly for network mapping, it executes external binaries whose effects depend on supplied network ranges—the core Execute category. Severity is high because reconnaissance tools enable downstream attacks; misuse could target unintended networks or generate network traffic that violates laws or contracts.

From the tool's own definition: "Tool named 'run_mapcidr' on a penetration testing server described as enabling 'autonomous execution' of 'reconnaissance' tools. MapCIDR is a CIDR utility tool for IP range manipulation and scanning."

## Use case

AI agents invoke run_mapcidr to trigger actions in Pentester-MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "run_mapcidr": {
      "limits": [
        {
          "counter": "run_mapcidr_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
