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

Frequently asked questions
Can my AI automatically find the details for a specific loyalty member by their ID?
Yes! Use the get_member tool with the Member ID. Your agent will respond with complete metadata, including current points, tier status, and enrollment date in seconds.
How do I find my PassKit Long-Lived API Token?
Log in to the PassKit Portal, navigate to Settings > Integrations, and you will find your unique secret token under the API Credentials section.
Does this work with both Apple and Google Wallets?
Absolutely. PassKit acts as a unified hub, allowing the AI to orchestrate digital passes that are cross-compatible with both major mobile wallet ecosystems.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
