Connect your AI client via MCP

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).

GlobalFoundries printed. I think some people totally missed that a mature-node foundry is guiding above 30% gross margin while the industry still talks about “commodity capacity.” Q2: - $1.786B revenue - 29.9% gross margin, above guide Q3: - $1.885B ± $25M - 30.5% ± 100bps gross margin That is the tell we wanted. This is not a broad foundry recovery. It is a scarcity story inside specific corridors: Vermont SiGe and silicon photonics capacity feeding optical connectivity. $GFS
