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).

Vaxcyte rockets about 50% after its 31-strain pneumonia vaccine VAX-31 hit the main goals of a Phase 3 trial in adults 50 and older, matching Pfizer's Prevnar 20 and Merck's Capvaxive on shared strains and beating them on three unique ones. Analysts call it near best case. U.S. filing planned for the first half of 2028. $PCVX @petenajarian @jonnajarian dig in because #ITSNOTANOPTION 📙 RebelCon 2026 Oct 19-21 Vegas 👉 https://t.co/3C7PXfQHvx
