Bitrefill MCP Server

A TypeScript-based MCP server that provides access to Bitrefill services, allowing you to search for gift cards, mobile topups, and more. This server implements the Model Context Protocol to expose Bitrefill functionality to AI assistants.

How It Works

The server operates using the Model Context Protocol (MCP) to communicate with Claude and similar AI assistants. It:

1. Runs as a standalone process using stdio for communication
2. Registers resources and tools for accessing Bitrefill services
3. Interfaces with the Bitrefill API to provide product search and details
4. Returns structured JSON responses that can be processed by AI assistants

Architecture

The app server follows this architecture:

Configuration

API Key Setup

To use the all the tools that rely on the Bitrefill API except for search, categories and detail, you need to set up Bitrefill API credentials:

1. Create a Bitrefill account
2. Ask for a developer API key by filing a request on this form
3. Create a .env file in the root directory (you can copy from .env.example)
4. Add your Bitrefill API credentials:

   BITREFILL_API_SECRET=your_api_key_here
   BITREFILL_API_ID=your_api_id_here
   

The create_invoice tool will only be available if the API credentials are set. If the API credentials are not set, the tool will not be registered and won't appear in the list of available tools.

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.

Installation

Installing via Smithery

To install Bitrefill for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @bitrefill/bitrefill-mcp-server --client claude

Claude Desktop
