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

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

## Why pivot_chisel_server is rated High

This tool executes a tunneling service whose effects depend on how the agent configures it (ports, authentication, forwarding rules). While not directly destructive or financial, it triggers an external operation (server startup) that could enable lateral movement, command execution on other systems, or persistent access.

From the tool's own definition: "Tool name 'pivot_chisel_server' and description 'Start a Chisel server for tunneling' indicate the tool launches a network tunneling server."

## Use case

AI agents invoke pivot_chisel_server to trigger actions in Zebbern Kali MCP. 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 Zebbern Kali MCP:

```json

          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
