usefulapi
Hosted MCP servers for the tools you already use — connect from Claude, Cursor, or any MCP client. No local install, no key-juggling: authorize once and go.
Portal: https://usefulapi.io
Servers
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" snippetserver.json— the official MCP Registry record (namespaceio.usefulapi/*), pointing at the hosted endpoint
