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).

I've been building a position in $STUB in the low $6s. $STUB has been a disaster since its IPO as it ramped S&M, cut fees, and increased pricing transparency to drive significant market share gains. Expectations are now very low even though $STUB finally showed a glimmer of operating leverage last quarter and the World Cup awaits. Importantly, $STUB could leverage its scale to benefit from improved marketplace dynamics due to the DOJ's pending settlement with $LYV. The following is an excellent thread on $STUB, be sure to read past the first Tweet...
