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.

8 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Passslot account to Claude via Composio Connect, enabling it to list all Apple Wallet passes I've created, show membership cards issued last week, find event tickets by pass type ID, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Passslot account

Back in Claude, ask it to connect to Passslot or give it any Passslot-related task.

For example, ask Claude to:

  • "List all Apple Wallet passes I've created"
  • "Show membership cards issued last week"
  • "Find event tickets by pass type ID"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Passslot account is ready to use.

What is the Passslot Claude Connector, and what's possible with it?

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.

  • Comprehensive pass listing: Instantly fetch descriptions and details for all wallet passes you've created, allowing for easy review and management.
  • Filtered retrieval by pass type: Direct your agent to list passes filtered by a specific pass type, making it simple to track event tickets, coupons, or membership cards separately.
  • Pass type discovery: Have your agent retrieve all available pass type identifiers, helping you understand what categories and templates you can use for new passes.
  • Organized pass management: Let your agent sort, paginate, and organize your digital passes, so you can quickly find and manage exactly what you need.

Troubleshooting

1. Why does Claude not use the Composio connector for Passslot?

The connector can show as connected, but Claude must use it in each Passslot conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Passslot again.

2. Why does Claude show an MCP server error before Passslot connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Passslot.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Passslot.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Passslot authorization link not work?

The Composio connector is one server. Your Passslot account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Passslot connection.
  • Composio creates a fresh Passslot authorization link.
  • Open that link in your browser and finish the Passslot sign-in.

4. Why do Passslot actions fail after they worked before?

The Passslot connection can expire or lose permission.

  • Ask Claude to inspect the Passslot connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Passslot account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Passslot.
  • If the action still fails with a permission error, check that the connected account has that permission in Passslot itself.

5. How do I switch to a different Passslot account?

Claude can manage the Passslot connection for you.

  • Ask Claude to disconnect or delete the current Passslot account.
  • Ask Claude to connect Passslot again.
  • Open the new Composio authorization link for Passslot.
  • Sign in with the other Passslot account in the browser.
  • After the account connects, ask Claude to retry the Passslot task.

6. Why is my Passslot connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Passslot connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Passslot tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Passslot.

FAQ

Frequently asked questions

With a standalone Passslot MCP server, the agents and LLMs can only access a fixed set of Passslot tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Passslot and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Passslot tools.

Yes, absolutely. You can configure which Passslot scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Passslot data and credentials are handled as safely as possible.
