Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://realtime-register.usefulapi.io/mcp.
- Claude Code:
claude mcp add --transport http realtime-register https://realtime-register.usefulapi.io/mcp, then run /mcp to log in.

- Cursor and other clients: add the URL as a remote MCP server:
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Realtime Register credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/realtime-register/
On first connect you provide a Realtime Register API key (created on your profile page; it is shown only once) and your customer handle (the account name in the API paths). The server validates it and stores it per user. No keys go in config files.
