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

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

## Why kali_network_tcpdump_capture is rated High

This tool actively captures live network traffic, which is an external operation with significant security implications. Packet capture can intercept sensitive data (credentials, session tokens, PII) traversing the network. It triggers a real-time network monitoring operation whose impact depends on the BPF filter arguments provided.

From the tool's own definition: "Capture network packets for analysis. Supports BPF filters and can save to PCAP files."

## Use case

AI agents invoke kali_network_tcpdump_capture to trigger actions in Kali 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)
