Overview

TCP Viewer is a native macOS packet capture and inspection tool built with AppKit and Wireshark libraries. It captures live network traffic, groups packets by app domain or IP, filters common protocols, follows TCP streams, opens PCAP and PCAPNG files, and exports captures for further analysis. It also includes an MCP integration that can let AI coding agents query network captures.
