# Nyna AI

> Nyna is an AI wedding planner (web app, PWA and MCP server) by Nyna AI SAS, Paris. Couples chat with Nyna to plan a wedding: a full plan, real vendors from an indexed directory (venues, caterers, photographers…), guest list and RSVPs, budget, checklist, seating, gift registry and a minute-by-minute wedding-day run sheet. Chat is free; a few generative actions spend credits. Fourteen UI languages; public pages in English and French.

## What Nyna does

- Plans a wedding from a conversation: date, venue, budget, guests, theme, then a step-by-step checklist.
- Finds real wedding vendors in 14 categories around any city in the world (51 featured cities have their own pages), with rating, review count, distance and address.
- Keeps the guest list (RSVP, roles, duplicates), the budget by category, the seating plan and the gift registry.
- Writes and runs the wedding day: run sheet, vendor confirmations, call sheet, contingency plans.
- Members with roles and missions (partner, witnesses, family) with rights per resource.
- Vendors (providers) claim and edit their listing, receive enquiries and see their stats.

## MCP server (for AI agents)

- Endpoint: https://nyna.ai/mcp (Streamable HTTP, stateless). Add it to any MCP client; Claude Code: `claude mcp add --transport http nyna https://nyna.ai/mcp`.
- Auth: OAuth 2.1 with PKCE (S256) and dynamic client registration; no API key. The directory tools need no account.
- Discovery: https://nyna.ai/.well-known/oauth-protected-resource, https://nyna.ai/.well-known/oauth-protected-resource/mcp, https://nyna.ai/.well-known/oauth-authorization-server
- Scopes: directory:read, wedding:read, wedding:write, planning:run, partner:read, partner:write. A token granted wedding:read is refused a write.
- Every error carries a machine-readable code and `changed: false, charged: 0`; unknown parameters are refused, never silently dropped.
- Users revoke an app in Profile → Connected apps; every token it holds stops working immediately.
