Bitrefill MCP Server (Sample Implementation)

This is a sample / reference implementation. For production use, connect to the official hosted Bitrefill eCommerce MCP at https://api.bitrefill.com/mcp instead. It is maintained by Bitrefill, supports OAuth, and exposes the same tools without you having to run, deploy, or update anything.

Use this repository if you want to learn how a Bitrefill MCP can be built, fork it, extend it, or self-host a customized variant on top of the Bitrefill API v2.

This server wraps the Bitrefill API v2 (https://api.bitrefill.com/v2) using Authorization: Bearer ${BITREFILL_API_KEY}. Only request parameters are validated with Zod; API responses are returned as JSON text unchanged.

Use the official remote MCP (recommended for production)

The Bitrefill eCommerce MCP is hosted by Bitrefill and is the recommended way to integrate with ChatGPT, Claude Desktop / Code, Cursor, and any other MCP-compatible client.

• OAuth (recommended). Point your client at:

  https://api.bitrefill.com/mcp

  You'll be redirected to Bitrefill to sign in and authorize access. No API key handling required.

• API key. Append your key from bitrefill.com/account/developers:

  https://api.bitrefill.com/mcp/YOUR_API_KEY

Setup guides per client: ChatGPT, Claude Desktop, Claude Code, Cursor.

When to use this repo instead

Run this local MCP only if you need to:

• Study a working reference implementation of a Bitrefill MCP server.

• Fork it to add custom tools, prompts, validation, logging, or routing.

• Self-host inside a private network or air-gapped environment.

• Experiment with a wider set of v2 endpoints (this sample exposes 18 tools, while the official remote MCP intentionally exposes a curated set of 7; see eCommerce MCP).

For everyday "buy gift cards / eSIMs from my AI assistant" use cases, prefer the hosted server above.

Configuration

1. Create an API key: Bitrefill account → Developers.

2. Set in the environment (or .env for local runs):

BITREFILL_API_KEY=your_api_key_here

If BITREFILL_API_KEY is missing, no tools are registered (v2 requires authentication even for ping).

Tools (v1.0.0)

Breaking change vs 0.x: old snake_case tool names (search, create_invoice, unseal_order, ...) were removed. Use the names above. There is no unseal_order in v2; GET /orders/{id} returns redemption_info when delivered.

Resources

• bitrefill://payment-methods: allowed payment_method strings for buy-products / create-esim-invoice

• bitrefill://category-slugs: B2B category query values for product list/search

• bitrefill://product-types: product family keys

• bitrefill://product-types/{productType}: category slugs per family

Development

pnpm install
pnpm run build
pnpm run typecheck
pnpm run lint

Smoke tests (this repo’s MCP only)

Smoke tests always start this package’s server (node build/index.js after pnpm run build). They do not open https://api.bitrefill.com/mcp or any other remote MCP URL.

Recommended: MCP client in-process (stdio to build/index.js):

pnpm run build
pnpm run smoke

Same as pnpm run test-services (alias).

Optional: MCP Inspector CLI, still only against this server:

pnpm run build
pnpm run smoke:inspector

All 18 tools (Inspector CLI, summary lines, dummy ids on purpose):

pnpm run test:inspector:all-tools

The Inspector uses --tool-arg key=value (repeat for multiple keys), not a single JSON blob. For nested data, use JSON in the value, e.g.
--tool-arg 'products=[{"product_id":"x","value":10}]'.

Interactive UI (local server only):

pnpm run build
pnpm run inspector

Examples:

pnpm dlx @modelcontextprotocol/inspector node build/index.js --cli --method tools/call --tool-name ping
pnpm dlx @modelcontextprotocol/inspector node build/index.js --cli --method tools/call --tool-name product-details --tool-arg id=test-gift-card-code

Client examples (self-hosted sample)

Reminder: for production, prefer the hosted https://api.bitrefill.com/mcp (OAuth) over the stdio config below.

Cursor / Claude-style MCP config, pass the key in env:

{
  "mcpServers": {
    "bitrefill": {
      "command": "npx",
      "args": ["-y", "bitrefill-mcp-server"],
      "env": {
        "BITREFILL_API_KEY": "your_api_key_here"
      }
    }
  }
}

Docker, e.g. -e BITREFILL_API_KEY=... or --env-file .env.

Hosted remote MCP (no install, recommended):

{
  "mcpServers": {
    "bitrefill": {
      "url": "https://api.bitrefill.com/mcp"
    }
  }
}
