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

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

## Why execute_python_script is rated High

Execute category applies because the tool runs code (Python scripts) whose effects depend entirely on the arguments provided—a malicious agent could execute arbitrary logic including system compromise, data exfiltration, or lateral movement. Severity is critical due to unrestricted blast radius in a penetration testing context where script execution is the primary attack vector.

From the tool's own definition: "Tool name 'execute_python_script' indicates arbitrary Python code execution. Empty description reduces evidence specificity but does not change the fundamental capability."

## Use case

AI agents invoke execute_python_script 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": {
    "execute_python_script": {
      "limits": [
        {
          "counter": "execute_python_script_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
