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

```json
{
  "jsonrpc": "2.0",
  "id": 1,

  "params": {
    "name": "pivot_chisel_client",
    "arguments": {}

## Why pivot_chisel_client is rated High

This tool executes Chisel, a legitimate but powerful tunneling utility. While Chisel itself does not directly execute arbitrary code, it enables network pivoting and tunnel establishment—operations whose effects depend on runtime arguments (target server, ports, credentials).

From the tool's own definition: "Tool name 'pivot_chisel_client' and description 'Start a Chisel client to connect to a Chisel server' indicate execution of network tunneling/proxy software."

## Use case

AI agents invoke pivot_chisel_client 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)
