Connect Nupty to your AI assistant

The Nupty connector lets an AI assistant work on your plan in Nupty while you chat: add the guests you dictate, compare vendor ideas, build the timeline of the day, keep the budget up to date. It uses the Model Context Protocol (MCP), the open standard behind the connectors of Claude, ChatGPT and Le Chat.

Connector URL

Add this URL as a custom connector. Your assistant then asks you to sign in to Nupty:

https://my.nupty.app/mcp

Without signing in, https://my.nupty.app/mcp/public offers one thing only: saving a plan (nupty.handoff v1) as a draft and giving you a link to it. You open the link, review the plan and sign up; drafts are kept encrypted for 7 days.

How to connect

Claude

On claude.ai or the desktop app: Settings → Connectors → Add custom connector.
Name: Nupty. URL: https://my.nupty.app/mcp. Add, then Connect.
Sign in to Nupty in the window that opens and allow access. Turn the connector on in a chat when you want Claude to use it.

ChatGPT

Settings → Apps & Connectors → Advanced settings: turn on developer mode (needed for custom connectors).
Create a connector: name Nupty, MCP server URL https://my.nupty.app/mcp, authentication OAuth.
Sign in to Nupty when asked and allow access.

Le Chat (Mistral)

Intelligence → Connectors → Add connector → Custom MCP connector.
Name: Nupty. Server URL: https://my.nupty.app/mcp. Choose OAuth.
Sign in to Nupty and allow access.

Claude Code and other MCP clients

claude mcp add --transport http nupty https://my.nupty.app/mcp — then /mcp in Claude Code to sign in.
Any client that supports remote MCP servers with OAuth (dynamic client registration and PKCE) connects the same way.

The assistants rename their menus from time to time; look for “connectors” or “apps”.

What you allow

You sign in with your Nupty account (e-mail or Google) and see what the assistant asks for: “Read and change your wedding plan in Nupty”.
That covers your own wedding only — never payments, your account, API keys, sending invitations or publishing your website.
Premium features stay Premium. Without Premium the assistant is told what needs it, with a link to the Premium page; it cannot buy anything.
To stop it, disconnect it in Nupty (Settings → Connected assistants) or in your assistant’s settings.

Staying connected, and disconnecting

Once connected, the assistant stays connected: you don’t sign in again for every chat. The connection lapses after 90 days without use, and after a year in any case; the assistant then asks you to sign in to Nupty again.
Disconnect in Nupty: Settings → Connected assistants → Disconnect. The assistant loses access at once, in every chat. To use it again, connect it again and allow access anew.
Disconnect in Claude: Settings → Connectors → Nupty → Disconnect, or remove the connector. In ChatGPT and Le Chat, remove or disconnect the connector where you added it. That makes the assistant forget the connection; to be sure nothing can use it any more, disconnect it in Nupty too.

What the assistant can do

The tools as the assistant sees them (generated from the same rules the planner uses, so this list is always complete). Their descriptions are in English.

Tool	What it does	Kind
`create_wedding_draft` Create a wedding plan draft in Nupty	Saves a wedding plan prepared with the couple (nupty.handoff v1, see get_handoff_schema) as a draft and returns a link. The couple opens the link, reviews the plan, unticks what they do not want and signs up; nothing is added to any account before that. Drafts are deleted after 7 days. Leave out anything the couple has not decided. Names only for guests: no e-mail addresses, phone numbers, dietary or health details, links or payment data.	no sign-in
`get_handoff_schema` Get the plan format	Returns the JSON Schema of nupty.handoff v1, the wedding plan format create_wedding_draft accepts, with an example.	no sign-in
`get_plan_summary` Get the wedding plan summary	Reads an overview of the couple's wedding plan in Nupty: names, date, place, guest estimate, ceremony, style, currency, budget (target, planned, committed, paid), guest replies, vendors, Big Day moments and to-dos.	reads
`list_guests` List guests	Lists the invitations on the guest list with their people, side, group and RSVP reply (names only: no e-mail addresses, phone numbers or dietary notes). Filters by reply, side, group or part of a name; pages with offset/limit.	reads
`list_vendors` List vendors and vendor ideas	Lists the vendor types in the plan (venue, photographer, catering…) with status, budget, cost of the chosen idea, amount paid, and the vendor ideas (options) being compared under each. Amounts are whole units of the plan currency.	reads
`get_timeline` Get the Big Day timeline	Reads the moments of the wedding day (time, name, length, linked vendor), in time order: the plan, or an alternative day version. Also lists the day versions; without Premium, alternative versions are read-only.	reads
`get_budget` Get the budget	Reads the budget: the total target, per vendor the planned budget, the cost of the chosen idea and what is paid, the all-in projection (min–max, counting undecided vendors from their ideas or budget) and every open payment by due date. Whole units of the plan currency.	reads
`list_todos` List to-dos	Lists the to-dos (general ones and those under a vendor), open ones only unless includeDone is true.	reads
`list_change_sets` List recent changes	Lists recent changes made to the plan from outside the planner (by assistants, API keys or a hand-off): when, by whom, what (in counts), and whether each can still be undone.	previews and undo
`update_wedding_details` Update wedding details	Changes the wedding's basic details: the couple's first names, the date (exact or only the month), the guest estimate, ceremony type, style, currency, total budget target, place and 12h / 24h time display. Only the given fields change.	changes
`add_guests` Add guests	Adds invitations to the guest list. Each entry is one invitation: a name ("Kati Nagy" or "Tamás & Éva Kovács"), an optional plus-one, number of children, side (p1, p2, both) and group. Names only: no e-mail addresses, phone numbers or dietary details. Names already on the list are skipped. Up to 300 per call.	changes
`update_invitation` Update an invitation	Changes one invitation: its side, group, priority, whether it is for the whole day or the evening only, and its people's names.	changes
`set_rsvp` Record RSVP answers	Records RSVP answers the couple received by hand: yes (and who is coming), no, or waiting. "waiting" on an invitation not sent yet marks it as invited without e-mail (a paper or WhatsApp invitation; no free send is used). Answers recorded here show as "Manually entered". Up to 100 invitations per call.	changes
`remove_guests` Remove guests	Removes invitations from the guest list (and frees their seats). Needs confirmation: returns a preview and a confirm token; confirm_change applies it.	changes, after a preview
`add_vendor_ideas` Add vendor ideas	Adds vendor ideas to compare: either under a Nupty vendor type ("item": one of venue, stay, ceremonyloc, rentals, catering, cake, bar, sweets, latenight, officiant, rings, cermusic, music, booth, fireworks, kids, entertainment, photo, video, drone, creator, florist, decor, stationery, lighting, dress, suit, hair, alter, bridesmaids, transport, planner, gifts, honeymoon, favours) or under the couple's own type ("custom": its name, with a category). Each idea has a name and optionally a price (whole units of the plan currency) and a note. Ideas with the same name under the same type are skipped. Nothing is marked as booked.	changes
`update_vendor` Update a vendor	Sets a vendor type's status (idea, comparing, booked, done) and/or its planned budget.	changes
`update_vendor_idea` Update a vendor idea	Changes one vendor idea: its name, fixed price or notes, or marks it as the chosen one for its vendor type.	changes
`remove_vendor_ideas` Remove vendor ideas	Removes vendor ideas. Needs confirmation: returns a preview and a confirm token; confirm_change applies it.	changes, after a preview
`add_vendor_notes` Add vendor agreements and notes	Adds dated entries to vendor types' "Agreements & notes" log (e.g. "deposit due on signing", "menu tasting 12 March"). An entry with the same text under the same vendor is skipped.	changes
`add_timeline_items` Add Big Day moments	Adds moments to the wedding day (time HH:MM and a name, e.g. "15:00 Ceremony"): to the plan, or to an alternative day version (alternative versions need Premium). A moment with the same time and a similar name is skipped.	changes
`update_timeline_item` Update a Big Day moment	Changes the time, name or length of one moment of the wedding day (the plan, or an alternative version with Premium).	changes
`remove_timeline_items` Remove Big Day moments	Removes moments from the wedding day (the plan, or an alternative version with Premium). Needs confirmation: returns a preview and a confirm token; confirm_change applies it.	changes, after a preview
`create_alternative_day` Create an alternative day (Premium)	Copies the wedding day into a new alternative version the couple can change and compare with the plan (up to 4 versions). A Premium feature: without Premium the result says so and links to the upgrade page.	changes
`set_budget_lines` Set budget lines	Sets the planned budget of vendor types (whole units of the plan currency; 0 = none). A suggested vendor type that gets a budget is added to the plan. Replacing more than one existing budget needs confirmation.	changes
`add_payments` Add payments	Adds payments (deposits, instalments) to vendor types: a label, an amount in whole units of the plan currency, an optional due date and whether it is already paid. Records them only; Nupty never moves money.	changes
`add_todos` Add to-dos	Adds general to-dos (a title and an optional due date YYYY-MM-DD). A to-do with the same title is skipped.	changes
`complete_todos` Tick off to-dos	Marks to-dos as done (or, with done: false, as open again).	changes
`remove_todos` Remove to-dos	Removes to-dos. Needs confirmation: returns a preview and a confirm token; confirm_change applies it.	changes, after a preview
`confirm_change` Confirm a previewed change	Applies a change that was previewed with a confirm token (removals, or replacing several existing values). A token works once, for 10 minutes, and only if the plan still looks like the preview.	previews and undo
`undo_change_set` Undo a change set	Reverts everything one earlier call changed (its change set), within 30 days. Refused if the couple or anyone else changed the same things afterwards.	previews and undo

Previews, undo and the activity log

Removing things, or replacing several existing values at once, never happens directly: the assistant gets a preview first and has to confirm it. A confirmation works once, for 10 minutes.
Everything one request changes is one change set. You see it in Settings → Activity (“Claude (AI assistant) · added 37 guests”) and in a short note at the top of the planner, each with Undo, for 30 days.
Undo is refused when you changed the same things afterwards, so it never overwrites your own edits.

Privacy

The assistant sees your plan: names, dates, vendors, budget, the day’s timeline. Guests’ e-mail addresses, phone numbers and dietary needs are never shared with it.
Nupty receives only what the assistant sends through these tools — never your chat.
Your assistant’s provider (Anthropic, OpenAI, Mistral…) keeps your chats under its own terms.

Limits

240 changes and 600 reads a minute per assistant.
Up to 64 KB per request (about 300 guests at a time).
