mcp-inspector is a CLI tool that acts as a local proxy to intercept, parse, and pretty-print Model Context Protocol (MCP) traffic. It provides human-readable, colorized logs of tool calls, arguments, and responses in your terminal. This drastically simplifies debugging for any developer building with the new AI agent and tool-use stack.

Imagine your terminal lighting up with a crystal-clear, structured view of every tool call your AI agent makes. mcp-inspector turns a black box of HTTP requests into an organized, color-coded log, showing you exactly what function was called, the arguments passed, and the data returned -- all in real-time. No more print() statements or digging through raw server logs.

    # 🕵️ MCP Inspector listening on http://127.0.0.1:8080

1. Point your agent's tool server endpoint to the proxy (e.g., update your environment variable from https://api.weather.com to http://127.0.0.1:8080). Watch the structured logs roll into your terminal.
