What is Mcpsnoop?
Mcpsnoop is an open-source tool that acts as a transparent proxy for Model Context Protocol (MCP) traffic, providing a live terminal user interface (TUI) for inspection and debugging. It solves the problem of visibility into MCP communication between AI agents and tools, which is often opaque during development. By intercepting MCP messages in real time, developers can see exactly what data is being exchanged, diagnose issues, and optimize interactions. The tool was launched as a Show HN on Hacker News, indicating strong community interest in MCP debugging utilities. It is built for developers working with MCP-based systems who need a network-level debugging experience similar to Wireshark but tailored for MCP. The project is hosted on GitHub and is actively maintained.
