Your merch. Inside your AI assistant.
Ask Claude, ChatGPT or Gemini what's in stock, what to send and what it costs. Sunday MCP prepares the kit, the quote and the shipment. You approve.
Included on every Sunday plan · You approve every order

Review quoteConnects to any assistant that speaks MCP
Merch lives in another tab.
Your work happens in your AI assistant now. Planning, writing, CRM lookups, event prep. Then someone asks for 200 onboarding kits and you're back to browsing a catalog, building a budget in a spreadsheet and chasing a quote.
The hard part was never clicking order. It was figuring out what to send, to whom, for how much.
Ask once. Get the kit, the quote and the plan.
Sunday MCP connects your whole Sunday platform to the assistant you already use. It searches the full catalog for you, uses what works for audiences like yours, and comes back with ideas, prices and a quote ready for your approval.
Everything you do in Sunday. In one prompt.
If you can do it in the platform, you can ask for it in Claude, ChatGPT or Gemini.
Product and kit ideas
Suggestions and pre-made kits that fit your audience, without browsing the full catalog.
Budgets and wish lists
Turn a budget and a target audience into a spend plan. Share it as a wish list.
Prices and quotes
Calculate prices and request quotes for any quantity, ready to approve.
Designs
Select products and request designs in your brand, straight from the chat.
Stock
Know what's in your warehouse right now, by product and size.
Reorders
One prompt instead of the whole process. Same as last time, new quote.
Shipments and gifts
Plan shipments and send merch or gifts. A person confirms before anything ships.
Reporting
Ask the data questions that used to take a report request.
The assistant prepares. You approve.
Sunday does not process any order without human verification. No automatic orders. No surprise shipments.
You ask
In plain language, in the assistant you already use.
Sunday MCP prepares
Suggestions, prices, a design request or a quote, built from your Sunday account.
You approve the quote
You review it and approve it yourself, through a link. Brand sign-off stays with you.
You confirm the shipment
Nothing leaves the warehouse until a person confirms it. Then we produce and ship to 200+ countries.
Connect Sunday to the rest of your stack.
Your assistant can talk to your CRM, your calendar and Sunday at the same time. That's where it gets interesting.
Gift the customers who matter right now.
With your CRM connected too, ask which customers would have the most impact this month. Then ask Sunday MCP what to send them. It builds the packs in the app. You approve and they ship.

Sunday, what should we send them? Keep it under €75 each.
Here are two pack options with prices for 20 recipients. Pick one and I'll prepare the quote.
Review packsForecast a quarter of event merch.
Load your event calendar and tell the assistant how much you hand out per event. Sunday MCP builds the forecast and prepares quotes for the next quarter or six months.
Here are our events for Q1. We hand out 1,000 to 1,500 items per event. Build a forecast and make quotes for the quarter.
Forecast ready per event and per product. I've prepared quotes for Q1 and a six-month option for you to compare.
Review quotesPut idle stock to work.
Ask what's sitting in your Sunday warehouse and who should get it. With your other systems connected, the assistant can match leftover items to customers or employees worth rewarding.
We have leftover stock in Sunday. Which customers or employees should we reward with it?

Sunday MCP, answered.
Sunday MCP is a Model Context Protocol server that connects your Sunday merchandise platform to AI assistants like Claude, ChatGPT and Gemini. You ask in plain language for product and kit suggestions, prices, quotes, designs, stock levels, shipments and reports. The assistant prepares the work. A person approves every order.
No. The assistant can prepare a quote and show it to you, but Sunday does not process any order without human verification. You approve the quote yourself through a link. Shipments also need a person to confirm them.
Any assistant or platform that supports MCP. That includes Claude, ChatGPT and Gemini. You add Sunday as a custom connector with the URL you receive when access is granted, then sign in with your Sunday account.
Sunday MCP is included on every Sunday plan. You pay for the merchandise you order, the same as in the platform. Access is on request while we roll it out.
Fill in the request form on this page. We review requests and grant access to your Sunday account. You then receive the connector URL and connect it to your AI assistant in a few minutes.
You connect with OAuth using your own Sunday account, so the assistant works inside your account and nothing else. It cannot place orders or ship anything without a person approving it.
We started using it internally first. We are now rolling it out to partners and agencies who handle merch requests for their clients, and to power users who run large merchandise programmes and want to test it.
No. Gifting is one part of it. Sunday MCP covers the whole merchandise job: suggestions, kits, pricing, quotes, designs, stock, reorders, shipments and reporting.
