Connect CrewAI to Passslot MCP. List all apple wallet passes i've created, show membership cards issued last week, and more using natural language, with authentication handled for you.
Passslot is a platform for creating and managing Apple Wallet passes, including tickets, coupons, and cards. It streamlines digital pass design, distribution, and updates for businesses and event organizers.
This guide walks you through connecting Passslot to CrewAI using the Composio tool router. By the end, you'll have a working Passslot agent that can list pass types and templates, fetch passes by type, and create and manage scanners through natural language commands.
This guide will help you understand how to give your CrewAI agent real control over a Passslot account through Composio's Passslot MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.
CrewAI is a powerful framework for building multi-agent AI systems. It provides primitives for defining agents with specific roles, creating tasks, and orchestrating workflows through crews.
Key features include:
The Passslot MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Passslot account. It provides structured and secure access to your Apple Wallet passes, so your agent can retrieve, search, and organize passes, as well as discover available pass types on your behalf.
Composio's Composio SDK helps agents find the right tools for a task at runtime. You can plug in multiple toolkits (like Gmail, HubSpot, and GitHub), and the agent will identify the relevant app and action to complete multi-step workflows. This can reduce token usage and improve the reliability of tool calls. Read more here: Getting started with Composio SDK
The tool router generates a secure MCP URL that your agents can access to perform actions.
The Composio SDK follows a three-phase workflow:
