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).

$INTC Intel切入NVIDIA先进封装供应链的时点可能从2028年Feynman提前到2027年Rubin Ultra,CoWoS独家依赖出现松动。 UBS的具体说法是NVIDIA给Rubin Ultra做产品分级,2-die保留在TSMC CoWoS-L,4-die改用Intel EMIB-T。CoWoS-L做4-reticle级die的良率和interposer尺寸都吃紧,前段时间Commercial Times报Rubin Ultra缩回dual-die,源头就是这个物理瓶颈。 EMIB-T在bridge里加TSV做垂直供电,解决了标准EMIB在HBM4级供电下的电压droop问题。封装尺寸支持到120x180mm,panel利用率约90%,CoWoS interposer的wafer利用率约60%。Bernstein估算EMIB-T单颗封装成本百元级,CoWoS千元级。 NVIDIA此前已确认在Feynman上让Intel承担I/O die(18A或14A),并在EMIB封装上拿约25%份额。Rubin Ultra 4-die SKU如果被确认属实,Intel封装进入NVIDIA供应链的时间表就从2028年提前到2027年。
