对注意力有中等影响（占 128k 上下文窗口的 0.67%）
这是每次将服务器的工具加载到模型上下文窗口时所消耗的大致 token 数。数值越高，可用于其他任务的注意力就越少。

}🟢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.
