# Voice School MCP Lesson Requests

> Public AI-facing specification for request-first online vocal lesson booking with Daria Klishina.

The MCP endpoint is `https://mcp.voice-school.com/singing-vocal-lesson-booking/mcp` using Streamable HTTP. The server creates lesson requests only; Voice School confirms the final lesson time manually.

Discovery metadata is available at `https://voice-school.com/server.json` and `https://voice-school.com/.well-known/mcp.json`.
Human-readable documentation is available at `https://voice-school.com/en/mcp/` and `https://voice-school.com/ru/mcp/`.

## Booking contract

- Default coach: Daria Klishina (`daria-klishina`).
- Default schedulable offer: `single-vocal-lesson`; 50 USD, 60 minutes.
- Daria schedule time zone: `Europe/Belgrade`.
- Regular request window: 09:00-20:00 local Belgrade time, every day.
- Minimum notice: 12 hours.
- A selected time creates a request, not a confirmed booking.
- Name and at least one contact method are required: email, phone, Telegram, or WhatsApp.
- Time and service may be omitted; this creates a no-time lesson request for manual follow-up.
- Do not expose student identities, busy intervals, private notes, internal IDs, secrets, or notification destinations.

## MCP tools
