Ticket Generator MCP Server

A Model Context Protocol (MCP) server that provides AI agents with access to the Ticket Generator APIs for managing tickets and events.

Overview

This MCP server acts as a bridge between AI agents and the Ticket Generator APIs, allowing AI assistants to:

• Generate ticket IDs with QR code images (base64 PNG)
• Get hosted ticket URLs with optional variable field overrides
• Send tickets via email, SMS, or WhatsApp
• Retrieve event details for all active events on your account

Prerequisites

• Node.js 18.0.0 or higher
• A Ticket Generator API key (obtain from https://apis.ticket-generator.com/client/api-docs/)
• (For local development) ngrok for exposing local server

Quick Start

1. Install dependencies:

   npm install

1. Start the server (HTTP mode):

   npm run dev:http

1. Expose locally with ngrok:

   ngrok http 3000

1. Configure your MCP client with the ngrok URL and your API key:

   {
     "mcpServers": {
       "ticket-generator": {
         "url": "https://your-ngrok-url.ngrok-free.app/mcp",
         "headers": {
           "Authorization": "your_ticket_generator_api_key"
         }
       }
     }
   }

API Key Security

Important: In HTTP transport mode, the API key is passed securely via the Authorization header from your MCP client configuration. It is:

• Session-specific — each client session has its own API key stored in memory
• Transmitted securely over HTTPS (production) or ngrok tunnel (development)

In stdio transport mode, the API key is read from the TG_API_KEY environment variable.

Usage

This MCP server supports two transport modes: HTTP (for development and production deployments) and stdio (for local CLI usage). In HTTP mode the API key is securely passed from your MCP client configuration via the Authorization header. In stdio mode the key is read from the TG_API_KEY environment variable.

Local Development with ngrok

1. Start the MCP server in HTTP mode:

   npm run dev:http

This will start the server on http://localhost:3000

1. In a separate terminal, expose your local server using ngrok:

   ngrok http 3000

1. Copy the ngrok forwarding URL (e.g., https://abc123.ngrok-free.app)

1. Configure your MCP client (Claude Desktop, Cursor, etc.) with the ngrok URL and your API key:

   {
     "mcpServers": {
       "ticket-generator": {
         "url": "https://abc123.ngrok-free.app/mcp",
         "headers": {
           "Authorization": "your_ticket_generator_api_key"
         }
       }
     }
   }

Production Deployment

For production deployment, follow these steps:

1. Deploy the server to your hosting platform (AWS, DigitalOcean, etc.)

1. Set the required environment variable:

   export MCP_TRANSPORT=http

Note: The server listens on 0.0.0.0:3000 (hardcoded in server.js).

1. Optional environment variables for production:

• CORS_ORIGINS — comma-separated allowed origins (e.g., https://yourapp.com)
• RATE_WINDOW_MS — rate-limit window in ms (default: 60000)
• RATE_MAX — max requests per IP per window (default: 60)
• JSON_LIMIT — JSON body limit (default: 200kb)
• LOG_FORMAT — morgan log format (default: combined)

1. Start the server:

   npm start

1. Configure your MCP client with your production URL:

   {
     "mcpServers": {
       "ticket-generator": {
         "url": "https://your-production-domain.com/mcp",
         "headers": {
           "Authorization": "your_ticket_generator_api_key"
         }
       }
     }
   }

Server Endpoints

• GET /health — Health check endpoint
• POST /mcp — MCP initialization and tool call handling
• GET /mcp — Server-to-client notifications via streaming
• DELETE /mcp — Session termination

Available Tools

The MCP server provides the following tools for AI agents:

#### 1. get_ticket_data Generates a ticket ID and its QR Code image (base64 PNG) for a given event. Optionally pass a ticket category and image width.

Parameters:

• eventId (required): The Ticket Generator Event ID for which the ticket should be created
• width (required): QR image width/height in pixels (square). Allowed range: 300–1500. Default: 300
• ticketCategoryId (optional): Ticket Category ID. If the event has only one category, this can be omitted

#### 2. get_ticket_url Returns a URL to the rendered QR Code ticket for the specified event (and optional category). You can optionally override up to 5 variable fields on the ticket design.

Parameters:

• eventId (required): Ticket Generator Event ID
• ticketCategoryId (optional): Ticket Category ID. Omit if the event has a single category
• variables (optional): Array of up to 5 variable field overrides, each with:
• value (required): Value for this variable (e.g., "Mark", "A2")
• header (optional): Header/label for this variable (e.g., "Name", "Seat"). Leave empty to use the default label defined in the design

#### 3. send_ticket Sends a generated ticket to a recipient via Email, SMS, or WhatsApp. You can include subject, body, and sender details, along with up to 5 custom variable fields.

Parameters:

• eventId (required): Ticket Generator Event ID
• ticketCategoryId (optional): Ticket Category ID. Omit if the event has a single category
• email (optional): Email address of the recipient (ticket will be sent here)
• phoneNumber (optional): Recipient's phone number for SMS delivery
• whatsApp (optional): Set true to send ticket via WhatsApp (requires phoneNumber)
• whatsAppConsent (optional): Whether the recipient has consented to receive WhatsApp messages (required if whatsApp is true)
