[Nyna](https://nyna.ai) 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**

## Claude Code

```bash
claude mcp add --transport http nyna https://nyna.ai/mcp
```

Or as a plugin (adds `/nyna:find-vendors`, `/nyna:guests` and `/nyna:day-of`):

```text
/plugin marketplace add Bros-AI/nyna-mcp
/plugin install nyna@nyna-mcp
```

## Cursor

One click: [Add Nyna to Cursor](cursor://anysphere.cursor-deeplink/mcp/install?name=nyna&config=eyJ1cmwiOiJodHRwczovL255bmEuYWkvbWNwIn0=) — or copy [`cursor/mcp.json`](./cursor/mcp.json) into `.cursor/mcp.json`.

```

## What you can ask

- "Find me 5 photographers in Lyon for July 2027"
- "Add Marie and Pierre Dupont to my guest list"
- "Draft the schedule for my wedding day"

## 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.
- Machine-readable summary: https://nyna.ai/llms.txt · technical docs: https://nyna.ai/for-agents · privacy: https://nyna.ai/privacy
