mcp.shop

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)

Related MCP server: FakeStore MCP

Architecture

The application is built on:

• Next.js B2B Starter Kit for the website

• Vercel MCP Adapter for MCP integration

• WorkOS AuthKit with MCP for authentication

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:

   • Website: http://localhost:3000

   • MCP Server: /mcp

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"]
    }
  }
}
