Wraps PassNinja's REST API so you can create, update, and manage Apple Wallet and Google Wallet passes directly from Claude or any MCP client. Exposes 18 tools covering pass templates, issued passes, and webhooks with full CRUD operations. The same binary works as both a standalone CLI and an MCP server over stdio. Ships as a one-click .mcpb bundle with code-signed, notarized binaries for macOS, Linux, and Windows. Useful when you're building customer loyalty cards, event tickets, or membership passes and want to issue or modify them conversationally instead of writing integration code. Handles CloudEvents webhooks for install, update, and uninstall events if you need to react to pass lifecycle changes.
