The Model Context Protocol is the open standard AI assistants use to connect to outside services. It lets Claude, ChatGPT or Gemini query the shop directly, with up-to-date information.

Does it cost anything?

Not from us. You only pay for the products and shipping you choose at checkout. Some assistant features depend on your plan with them.

Can the assistant get a price wrong?

The valid price is always the one in our checkout, worked out at that moment from the catalogue. Review your cart before paying.

Do I need an account?

Not to browse and prepare a purchase. For the assistant to see your orders, yes: linking opens the shop's page, where you sign in or create an account, and shows exactly what the assistant may see. It can never pay, order for you or see your password.

Yes, any time: in the assistant, where you added it, and in My account → Connected AI assistants. We keep nothing from your conversation.

MYGU MCP

Connect MYGU to your AI assistant — Claude, ChatGPT or Gemini — and ask it to help you find, compare and buy. The assistant checks the catalogue, prices, stock and shipping in real time and prepares your cart; you review it and pay on our website.

MCP server address

https://mygu.pt/mcp

Browsing, advice and preparing a purchase need no account or key. For the assistant to see your orders and addresses, link your account: you sign in on the shop's secure page and the assistant never sees your password.

What the assistant can do

Search products by keyword, category or price
Suggest gifts by occasion, budget and taste
Show details, options, personalisation, stock and reviews
Work out shipping and the estimated delivery date
Check discount codes
Prepare a link with your cart ready to pay
Answer about shipping, returns and payments, with the source
With your account linked: see your orders, tracking and addresses
Send the shop a message or subscribe to the newsletter, when you ask

Safe by design

You always pay yourself, on our website's secure payment page. The assistant never sees or asks for card details.
The assistant cannot place orders on its own: it gives you a cart link that you review before buying.
Without a linked account, checking an order needs its number and the email used. With it linked, the assistant sees only your own orders, and you can disconnect it in My account.

How to connect, step by step

Claude

claude.ai and the Claude desktop app, on every plan (one custom connector on the free plan). Once added, it also works in the mobile app.

1Open claude.ai (or the desktop app) and go to Customize → Connectors.
2Click “+” and choose “Add custom connector”.
3Type the name “MYGU” and paste the address https://mygu.pt/mcp. For authentication, choose “Sign in when needed”.
4Click “Add”. In a chat, turn the connector on from “+” → Connectors and ask away.
5When you ask about your orders, Claude opens the shop's page for you to sign in (or create an account) and allow it. Once done, it stays linked.

On Team or Enterprise accounts, the organisation owner adds the connector first; then each person clicks “Connect”.

ChatGPT

chatgpt.com, on plans that allow adding custom MCP servers (OpenAI keeps widening the list; check your settings).

1Open chatgpt.com and go to Plugins (on some accounts: Settings → Apps & connectors → Advanced → Developer mode).
2Click “+” → “Add custom MCP server” (or “Create”).
3Name: “MYGU”. URL: https://mygu.pt/mcp. Authentication: OAuth (ChatGPT discovers the rest by itself). Accept the notice and install.
4In a chat, type “@MYGU” (or pick it from the “+” menu) and ask away.

Gemini

Gemini CLI, in any country. The Gemini app only accepts MCP “custom apps” in the US for now; when it reaches your country, paste the same address in Settings → Connected apps → Add a custom app.

1Install Gemini CLI (geminicli.com) and open a terminal.
2Run the command below (or add the block to ~/.gemini/settings.json).
3Open Gemini CLI, check with /mcp that MYGU shows as connected and ask away. For your orders, run /mcp auth mygu and sign in in the browser.

gemini mcp add --transport http -s user mygu https://mygu.pt/mcp

// ~/.gemini/settings.json
{ "mcpServers": { "mygu": { "httpUrl": "https://mygu.pt/mcp" } } }

Claude Code, VS Code, Cursor…

Any app that supports MCP over HTTP (Streamable HTTP).

1Add an HTTP MCP server with the address https://mygu.pt/mcp. No headers or key needed.
2In Claude Code, the command below is all it takes.

claude mcp add --transport http mygu https://mygu.pt/mcp

AI apps rename their menus often. If you can't find the option, look for “connectors”, “apps” or “MCP” in settings.
