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.

"context_servers": {
"mcp-inspector": {
"command": {
"path": "npx",
"args": [
"-y",
"@modelcontextprotocol/inspector"
]
}
}
}
}加入 context_servers。Zed 儲存後熱重載。
claude mcp add mcp-inspector -- npx -y @modelcontextprotocol/inspector一行命令搞定。用 claude mcp list 驗證，claude mcp remove 移除。
何時使用： Claude says 'tool failed' and you need to see what really happened.
結果： Server bug isolated without LLM noise.
