More servers land here as they launch — each is a folder with its own README + server.json, and a tile on the portal.

What's in each folder

  • README.md — what the server does, tools, pricing, the "Add to Claude" snippet
  • server.json — the official MCP Registry record (namespace io.usefulapi/*), pointing at the hosted endpoint
