MCPs βΊ Dev tools βΊ Vitamin D Explorer
Ask "can I make vitamin D right now?" for anywhere on Earth. The answer accounts for your skin type, your age, how much skin is exposed, and the weather that is actually happening β not a seasonal average. Live UV from Open-Meteo over a Madronich clear-sky model. **Nine tools need no account:** current status, today's window, the whole year for one city, a comparison across cities, a five-day forecast, sun times, city search and a session estimator. **Six more work with a connected account** (OAuth 2.1, dynamic client registration + PKCE): your profile, your cities, and a sun history you can read, answer and correct from the conversation. Clients that support MCP Apps render six inline widgets β the day's verdict, the year as a strip, a city comparison, a forecast, an editable profile and a tappable calendar. Clients that do not get exactly the same answer as text. - Public endpoint (no auth): `https://getvitamind.app/api/mcp/mcp` - Account endpoint (OAuth): `https://getvitamind.app/api/mcp-auth/mcp` - Setup guide: https://getvitamind.app/connect Send both `content-type: application/json` and `accept: application/json, text/event-stream`. Without the event-stream part the server replies 406 before running anything.
