## Facts

- Tool: `ssh_estimate_transfer`
- Server: Zebbern Kali MCP (`zebbern/zebbern-kali-mcp`) — https://policylayer.com/tools/zebbern-zebbern-kali-mcp.md
- Homepage: https://github.com/zebbern/zebbern-kali-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why ssh_estimate_transfer is rated Low

The tool only estimates (calculates/predicts) file transfer time — a read/computational operation with no side effects. It does not actually transfer files or execute commands on remote systems. However, given the broader Kali Linux penetration testing context and sibling tools focused on offensive security, there is some risk of misuse, but the described functionality is purely informational.

From the tool's own definition: "Estimate file transfer time over SSH"

## Use case

AI agents call ssh_estimate_transfer to retrieve information from Zebbern Kali MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Zebbern Kali MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "ssh_estimate_transfer": {}
  }
}
```

## 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`
