ZBD MCP Server

⚠️ DEPRECATION NOTICE

🚨 This MCP Server is no longer maintained. 🚨

We’ve moved to a new and improved MCP Server implementation. All future updates, features, and support will be provided there.

👉 Please migrate to the new MCP Server here: https://github.com/zebedeeio/zbd-payments-typescript-sdk/tree/main/packages/mcp-server

This repo will remain available for reference, but is not recommended for production use.

ZBD MCP Server (deprecated -- use this instead: https://github.com/zebedeeio/zbd-payments-typescript-sdk/tree/main/packages/mcp-server)

Add Bitcoin powers to your LLM.

Base SDK

This MCP server uses the official TypeScript SDK -- https://github.com/modelcontextprotocol/typescript-sdk

Prerequisites

Node.js 23+ (or Bun/Deno/Anything that supports running .ts files)
Bun (for building executables)
ZBD API key for payment processing

ZBD Setup

Get your API key from the ZBD Developer Dashboard and put it in a new .env file under ZBD_API_KEY=XXXXXXXXXXXX (check .env.example for an example).

Once that's done run the pnpm build command and setup the MCP server on your client (e.g. Claude Desktop or Cursor).

Installing Bun

If you don't have Bun installed, you can install it using one of the following methods:

macOS and Linux

# Using curl (recommended)
curl -fsSL https://bun.sh/install | bash

# Using Homebrew
brew install oven-sh/bun/bun

# Using npm
npm install -g bun

Windows

# Using PowerShell
powershell -c "irm bun.sh/install.ps1|iex"

# Using npm
npm install -g bun

# Using Scoop
scoop install bun

Verify your installation by running:

bun --version

Installation

pnpm install

Troubleshooting

Use ps aux | grep mcp-zbd | grep -v grep to list all running ZBD MCP Server instances.
Use pkill -f mcp-zbd to kill any duplicate ZBD MCP Server instances that may linger.

Project Structure

This project demonstrates a modular approach to building MCP tools:

Each tool is defined in its own TypeScript file in the src directory
Each tool can be built into a standalone executable in the bin directory
The main index.ts provides the actual tooling implementation

Available Tools

ZBD (src/zbd.ts): ZBD API for global Bitcoin Lightning payments

Creating New Tool

To create a new tool:

Create a new TypeScript file in the src directory (e.g., src/mytool.ts)
Use the existing tools as templates
Add a build script to package.json:

"build:mytool": "mkdir -p bin && bun build src/mytool.ts --compile --minify --sourcemap --outfile bin/mcp-mytool"

Update the build:all script to include your new tool

Usage

Building Executables

# Build all tools
pnpm build

# Build a specific tool
pnpm build:zbd

The resulting executables will be in the bin directory and can be run directly:

./bin/mcp-zbd

Cursor Notes

When using these tools with Cursor, always use the full path to the executable:

/path/to/your/project/bin/mcp-zbd

Alternatively, you can run the TypeScript files directly with Node:

/path/to/node ~/path/to/project/src/index.ts

Testing

# Run all tests
pnpm test

# Run tests in watch mode
pnpm test:watch

# Run tests with coverage
pnpm test:coverage
