The official debugger for MCP servers — connect to any server, call its tools live, see the raw protocol traffic.
MCP Inspector is the canonical dev tool for MCP. Point it at a server (local or remote), enumerate tools and resources, fire calls with structured inputs, and watch frames go by. First thing to reach for when your server misbehaves.

언제 쓸까: Claude says 'tool failed' and you need to see what really happened.
결과: Server bug isolated without LLM noise.
