# MCP Inspector

### What is Tairon Inspector? <a href="#what-is-testra-inspector" id="what-is-testra-inspector"></a>

Tairon Inspector is a web-based tool that lets you interactively test and debug MCP servers. It provides a live interface to send requests, view responses, check server health, and validate that endpoints behave correctly, all without writing code.

It’s designed to help developers quickly verify server functionality, diagnose issues, and understand the expected inputs and outputs for MCP-compliant endpoints.
