Create wallet passes from Claude, ChatGPT and any AI assistant
Describe a card in a sentence and it lands in Apple Wallet and Google Wallet. Your assistant can update it, message everyone who saved it and add loyalty stamps, through WalletPassBuilder’s MCP server.
New accounts get free pass credits to start. No code needed.

13 tools for Apple Wallet and Google Wallet
A remote MCP server any client can use. Your assistant chooses the tool from what you ask; you never call them by name.

Make a pass for both wallets, a loyalty program, or one card per person, with share links.

Change only what you name; every saved copy updates.

Change one person's details, like their tier or points.
get_pass
A pass's design, links and recipients.

https://walletpassbuilder.com/api/mcp
Transport
Streamable HTTP, remote. Nothing to install.
Sign-in

Credits
Same as the dashboard: 1 per pass created or saved to a wallet, whichever total is higher. Updates, messages and reads are free.
Prefer code? The same actions are in the REST API.
Zapier, Make and n8n
Native apps are on the way. Today, automations already create passes when an order or sign-up comes in from Shopify, Stripe Checkout, Square, WooCommerce, Jotform or Typeform, and Make and n8n can call the REST API with your API key from their HTTP steps.
Questions about the integrations
Does it cost extra?+
No. Assistants use the same pass credits as the dashboard and the API: 1 per pass created or saved to a wallet, whichever total is higher. Updating cards, sending notifications and reading your passes don't use credits. New accounts get free pass credits to start.
Do I need to write any code?+
No. Add WalletPassBuilder as a connector in Claude or an app in ChatGPT, sign in once, and describe what you want in plain words.
What can the assistant do with my account?+
Create, update and archive passes, send lock-screen notifications, add loyalty stamps, and read your passes, loyalty customers' names and progress, and credits. It can't see or change your billing, API key, team, password or customers' phone numbers, and you can disconnect it at any time under API, then Connected apps.
Will it message my customers without asking?+
WalletPassBuilder tells the assistant to show you the exact message and get your yes before sending, and Claude and ChatGPT can also ask for your approval before running an action.
Which assistants work?+
Claude (from its Connectors Directory, on the web, desktop and mobile), ChatGPT Business, Enterprise and Edu on the web, Claude Code, Cursor, VS Code, and any other client that supports remote MCP servers.
Is there an MCP server for Apple Wallet passes?+
Yes. WalletPassBuilder runs a remote MCP server at https://walletpassbuilder.com/api/mcp that creates, updates and messages Apple Wallet and Google Wallet passes.
Can Claude create an Apple Wallet pass?+
Yes. Connect WalletPassBuilder from Claude's Connectors Directory, describe the pass, and Claude creates it and gives you a link that adds it to Apple Wallet on an iPhone or Google Wallet on an Android phone.
Who on my team can connect an assistant?+
An account admin with access to every workspace, the same people who can manage the API key. If they leave the team, any assistant they connected stops working.
Where do I get help connecting?+
Email [email protected] with the assistant you're using and what you see. To disconnect an assistant, open API in the dashboard, then Connected apps, and click Disconnect.
