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).

The pros are that it's already native in your AWS, your data residency is all good there, you have all the HIPAA and standards that come with your AWS agreement, you get one single invoice, you can use AWS usage commitments, and you have one gateway for multimodal providers. The cons are there is sometimes a feature lag when comparing to direct API access at one of the model providers, and there is usually a thin extra layer of latency; usually it's sub-100 milliseconds. From a cost perspective, he doesn't believe there is a difference. 2. For AWS & the hyperscalers, the play is more in the clients using
