Nyna MCP — the AI wedding planner, in your AI assistant

Nyna plans weddings in a conversation: a full plan, real vendors from an indexed directory (venues, caterers, photographers…), the guest list and RSVPs, the budget, the checklist and a minute-by-minute wedding-day run sheet.

This repository holds the client-side packaging of Nyna's remote MCP server. There is nothing to run: the server lives at https://nyna.ai/mcp (Streamable HTTP, OAuth 2.1 with PKCE and dynamic client registration). The directory tools answer with no account; a couple's own wedding appears after one sign-in.

Step-by-step install for every client, with copy buttons: https://nyna.ai/assistants

Tools, cost, privacy

Every tool description opens with its tier: [Free], [Sign-in required], [Partner] or [Credits: N]. Chat with Nyna is free; a wedding plan costs 5 credits and a vendor search 2; every account starts with 500 free credits.
Scopes are granted by name (directory:read, wedding:read, wedding:write, planning:run, partner:read, partner:write); a token with wedding:read is refused a write.
Every refusal carries a machine-readable code and changed: false, charged: 0. Unknown parameters are refused, never silently dropped.
Revoke an app at any time in Profile → Connected apps on nyna.ai.
