TCP Viewer is a macOS application for capturing and analyzing network packets. Built on Wireshark's packet analysis engine, it provides a native Mac interface for inspecting TCP, UDP, DNS, HTTP, TLS, and WebSocket traffic. The project describes itself as an alternative to Wireshark.
Key features include live packet capture with grouping by app, domain, or IP address; protocol filtering; PCAP/PCAPNG file import via drag-and-drop; TCP and UDP stream reassembly; and an MCP integration for querying captures with AI agents. The app is open-source under GPL v2 and requires Apple Silicon macOS 15+.
