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

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

## Why kali_password_hashcat_crack is rated High

This tool executes hashcat, a password cracking utility, which actively runs computational processes to crack password hashes. It is an Execute-category tool because it runs an external program with user-supplied arguments (hash type, wordlist, target hashes). The severity is critical because an AI agent could use it to crack credential hashes at scale, enabling unauthorized account access across systems.

From the tool's own definition: "'Advanced password recovery tool using GPU acceleration. Supports 300+ hash types.'"

## Use case

AI agents invoke kali_password_hashcat_crack to trigger actions in Kali MCP Server. 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 Kali MCP Server:

```json
