## Facts

- Tool: `testssl_scan`
- Server: Kali Linux MCP Server (`alessandroannini/kali-mcp-server`) — https://policylayer.com/tools/alessandroannini-kali-mcp-server.md
- Homepage: https://github.com/AlessandroAnnini/kali-mcp-server
- Risk category: Execute (High risk)
- Registry record: grade D, 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": "testssl_scan",
    "arguments": {}
  }
}
```

## Why testssl_scan is rated High

This tool executes testssl.sh, an external security scanning program that probes SSL/TLS configurations on remote hosts. It runs active network operations against targets, placing it in the Execute category. Severity is high because it can be directed at arbitrary hosts to probe for vulnerabilities, potentially constituting unauthorized security scanning of third-party systems if misused by an AI agent.

From the tool's own definition: "'Test SSL/TLS configuration and vulnerabilities with testssl.sh' — runs the testssl.sh tool against a target host, triggering external network operations"

## Use case

AI agents invoke testssl_scan to trigger actions in Kali Linux 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 Linux MCP Server:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
