Overview

This project demonstrates how to use AuthKit with MCP to create a secure web shop where users can:

  • Connect to an MCP server
  • Authenticate via AuthKit
  • Order t-shirts using MCP tools
  • View order details (admin users only)

Architecture

The application is built on:

Key components:

  • Authentication logic: lib/with-authkit.ts
  • Client registration: app/.well-known/
  • MCP implementation: app/[transport]/route.ts

Prerequisites

  • Node.js (latest LTS version recommended)
  • WorkOS account with AuthKit configured
  • Redis service (e.g., Upstash)

Setup

  1. Clone the repository

  2. Install dependencies:

    pnpm install

  3. Configure environment variables:

    Copy .env.example to .env.local and set each environment variable appropriately.

    Note:

    • You can find your WorkOS credentials in the WorkOS dashboard.
    • Make sure to set your redirect URI (http://localhost:3000/callback for local development or https://<deployed-url>/callback for production) in the dashboard.
    • Make sure you have enabled Dynamic Client Registration on the dashboard. It should be under Developer -> Application -> Configuration page on the dashboard

  4. Start the development server:

    pnpm dev

    The application will be available at:

Connecting to MCP

To connect your chat client to the development server, add the following configuration to your MCP config file (e.g., .cursor/mcp.json):

{
  "mcpServers": {
    "mcp.shop": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "http://localhost:3000/mcp"]
    }
  }
}
