mcpsnoop MCP Debugging Skill

Skill by ara.so — MCP Skills collection.

mcpsnoop is a transparent proxy for Model Context Protocol (MCP) that sits between your AI client (Claude Desktop, Cursor, Claude Code) and your MCP servers. Unlike the official MCP Inspector which connects as a separate client, mcpsnoop intercepts the actual traffic between your real client and server, showing every JSON-RPC frame live in your terminal.
