Endpoint (paste into an MCP client — anonymous, free, no key)
https://mcp.koalcheck.com/mcp
Or copy this and send it to your AI to set it up:

Add the "koalcheck" MCP server to my client and connect. It is a remote Streamable-HTTP server at https://mcp.koalcheck.com/mcp — connect anonymously, no API key or login needed (the free tools work right away). If my client supports a remote/HTTP MCP server directly, just use that URL. If my client config only accepts a local command (e.g. Claude Desktop's mcpServers, which rejects a bare "url"), bridge it with command "npx" and args ["-y","mcp-remote","https://mcp.koalcheck.com/mcp"]. Then tell me to fully restart the client, and list the koalcheck tools you can call. It provides US-equity research tools built on an analyst track-record engine (who has actually been right, priced vs SPY, cross-checked with SEC & FINRA).

$MRVL CEO Matt Murphy 今天在Computex做了公司历史上第一次keynote,Jensen客串上台十分钟。整场的核心论点:AI scaling的下一个瓶颈在connectivity。 Matt的逻辑链条很清晰。当AI workload需要数万甚至上百万颗处理器作为一台引擎运转,真正卡脖子的地方从compute转移到了数据在处理器之间的传输。他提了一个概念叫”copper wall”,给了具体数字:200Gbps per lane下铜缆有效距离约2.5米,到400Gbps per lane铜缆基本无法完成rack内的完整互连。铜缆的可用边界在往rack内部收缩,速度在加快。 然后Matt问了一个问题:如果光互连消除了距离约束,数据中心的架构会变成什么样? 他的答案是完全disaggregated的系统。今天server的设计本质上是被铜缆距离限制倒逼出来的固定配比,CPU、GPU、memory必须紧挨在同一块板上。换成光互连之后,这个物理前提消失了。CPU独立成池,GPU独立成池,memory独立成池,按需调配,每类资源的利用率可以独立优化。Scale-up domain从当前的144颗XPU扩展到数千颗。单个数据中心成为campus的一部分,多个campus通过光互连组成跨区域的统一计算资源。他把这个愿景叫”data center without distance”。 现场展示了几个实物锚点。51.2T的CPO交换机(16×3.2T optical engines),1.6Tbps 2nm coherent optical solution今年晚些sampling。至少说明这条路线有产品在往前走。 Jensen上台那段也值得留意。他给了一句定调的话:“use copper wherever you can, use optics where
