Show HN: Mcpsnoop – Wireshark for MCP (transparent proxy and live TUI)
Summary
Mcpsnoop is a 'Wireshark for MCP'—a transparent proxy that sits in the data path to reveal live JSON-RPC frames between an AI client and MCP servers via a terminal UI. It offers live streaming of requests and responses, replay, a capability inspector, frame search, and zero-config operation, aimed at debugging AI/MCP integrations. The project is open source (MIT) and provides installation options including Go install and Homebrew.
