New AI Debugging Tool: MCPShark Viewer Visualizes MCP Protocol Traffic

MCPShark Viewer is an extension tool designed specifically for VS Code and Cursor editors, created to help AI developers easily monitor and debug MCP (Model Context Protocol) communication traffic. With this tool, developers no longer need to frequently switch between terminals and log files—they can directly view MCP communication data in real-time within the editor, significantly improving debugging efficiency for AI application development. Developed by the MCPShark team, the tool provides complete download links for the VS Code Marketplace, a GitHub repository, and an official website. The author is also actively seeking user feedback to understand which features could make MCP debugging more convenient, such as timeline views, session grouping, parameter comparison, and trace exporting. For developers building MCP AI agents or tools, this tool is undoubtedly a powerful assistant that can significantly simplify the debugging process and enhance the development experience.
