What is the PassKit MCP Server?

Connect your PassKit account to any AI agent and take full control of your digital wallet orchestration through natural conversation. PassKit is the premier platform for creating and managing cards for Apple Wallet and Google Wallet, and this integration allows you to issue loyalty cards, event tickets, and boarding passes directly from your chat interface.

What you can do

  • Membership & Loyalty Orchestration — Enroll and manage loyalty program members programmatically and retrieve detailed tier metadata to ensure your customer data is always synchronized.
  • Event Ticket Lifecycle Management — Issue digital event tickets and monitor usage statuses directly from the AI interface to drive better attendee engagement.
  • Boarding Pass & Flight Intelligence — Create and manage flight boarding passes via natural language to maintain a clear overview of passenger travel itineraries.
  • Coupon & Campaign Control — Create and manage digital coupons to ensure your promotional campaigns are always optimized using simple AI commands.
  • Operational Monitoring — Track system responses and manage branding assets (images) to ensure your pass designs are always high-fidelity.

How it works

1. Subscribe to this server
2. Enter your PassKit Long-Lived API Token from your dashboard settings
3. Specify your regional Base URL (e.g., https://api.pub1.passkit.io for EU/Asia)
4. Start managing your digital passes from Claude, Cursor, or any MCP-compatible client

No more manual pass generation or switching between wallet dashboards. Your AI acts as a dedicated digital wallet coordinator or customer engagement lead.

Who is this for?

  • Retailers & Marketers — quickly retrieve loyalty summaries and monitor program growth without switching apps.
  • Event Organizers — automate the issuance of digital tickets and track entry metrics via natural conversation.
  • Travel Providers — streamline the retrieval of flight metadata and monitor passenger check-ins directly within the chat.
