What is MCP Sniffer?
MCP Sniffer is a tool designed to monitor and analyze network traffic within MCP (Model Context Protocol) environments. It functions as a reverse proxy between MCP clients and servers, intercepting all data exchanged during communication. The captured data includes request and response payloads, which can be visualized through an easy-to-use web UI resembling Chrome DevTools. This allows developers to debug, monitor, and optimize MCP interactions in real-time, ensuring efficient protocol handling, troubleshooting issues, and gaining insights into MCP traffic flows for improved system performance.
