4. Connect your Passslot account

Back in Cowork, ask the agent to connect to Passslot or give it any Passslot-related task.

For example, ask Cowork to:

  • "List all Apple Wallet passes I've created"

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Passslot through MCP without you sharing account credentials directly with the agent.

What is the Passslot MCP server, 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.

FAQ

What are the differences in Tool Router MCP and Passslot MCP?

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.

Can I use Tool Router MCP with Claude Cowork?

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.

Can I manage the permissions and scopes for Passslot while using Tool Router?

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.

How safe is my data with Composio Tool Router?

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.
