コンテキストコスト
~862トークン数（ツール定義）
~4.2 KB一般的なレスポンスサイズ
注意への影響は中程度（128k コンテキストの 0.67%）
これは、サーバーのツールがモデルのコンテキストに読み込まれるたびに消費されるおおよそのトークン数です。数が多いほど、ほかのタスクに使える注意が減ります。

}🟢inspect_endpoint(url, headers)
Connects to a remote MCP endpoint (Streamable HTTP, then legacy SSE), lists its tools, and classifies each tool's side effects from its MCP hints. Never calls a tool on the target. A target problem is status=failed with a stable failure code (e.g. TARGET_UNAVAILABLE, TARGET_AUTH_FAILED, MCP_PROTOCOL_ERROR). Private and loopback addresses are rejected.
