_More servers land here as they launch — each is a folder with its own README + `server.json`,
and a tile on the [portal](https://usefulapi.io)._

## What's in each folder

- `README.md` — what the server does, tools, pricing, the "Add to Claude" snippet
- `server.json` — the [official MCP Registry](https://registry.modelcontextprotocol.io) record
  (namespace `io.usefulapi/*`), pointing at the hosted endpoint
