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

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

## Why hashpump_attack is rated High

The tool name 'hashpump_attack' strongly implies executing a hash length extension attack, a well-known offensive cryptographic technique. While the description is empty (lowering confidence), the server context (offensive penetration testing platform) and sibling tools (attack suites, payload generation, aircrack) confirm this is an offensive execution tool.

From the tool's own definition: "Tool name 'hashpump_attack' on a penetration testing platform; sibling tools include payload generation, attack suites, and aircrack tools indicating offensive security operations"

## Use case

AI agents invoke hashpump_attack to trigger actions in Nyxstrike. 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 Nyxstrike:

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