mcpsnoop vs sipnab

mcpsnoop: mcpsnoop is a transparent proxy designed for the Model Context Protocol (MCP), acting like Wireshark for AI client-server interactions. It allows developers to live-debug actual MCP traffic in a terminal UI, addressing limitations of existing tools by observing real client-server communications.; sipnab: sipnab is a static binary tool designed to analyze SIP calls, pinpointing reasons for failure by examining live traffic, pcap files, or HEP feeds. It offers comprehensive insights into call flow, RTP quality, and security signals through an interactive TUI, CLI, or JSON output.
