Usage Pattern

For optimal interaction with the BTCPayServer API through MCP:

1. Discover: Use get_service_info to explore available methods

get_service_info(serviceName: "invoices")

2. Understand: Use get_method_info to learn parameter requirements

get_method_info(serviceName: "invoices", methodName: "create")

3. Execute: Use btcpay_request to perform the operation

btcpay_request(serviceName: "invoices", methodName: "create", parameters: {storeId: "your-store-id", amount: "10.00", currency: "USD"})

Installation

1. Clone this repository:

git clone <repository-url>
cd btcpayserver-mcp

2. Install dependencies:

npm install

3. Build the project:

npm run build

Configuration

The MCP server requires the following environment variables:

• BTCPAY_BASE_URL - Your BTCPayServer instance URL (e.g., https://btcpay.example.com)

• BTCPAY_API_KEY - Your BTCPayServer API key

• BTCPAY_STORE_ID - (Optional) Default store ID for operations

Setting up BTCPayServer API Key

1. Log into your BTCPayServer instance

2. Go to Account → Manage Account → API Keys

3. Click Generate Key

4. Select the required permissions for your use case:

   • Store management: btcpay.store.canmodifystoresettings

   • Payment requests: btcpay.store.cancreateinvoice

   • User management: btcpay.user.canmodifyprofile

   • Webhooks: btcpay.store.webhooks.canmodifywebhooks

   • etc..

5. Copy the generated API key

Environment Setup

Create a .env file in your project root:

BTCPAY_BASE_URL=https://your-btcpay-instance.com
BTCPAY_API_KEY=your_api_key_here
BTCPAY_STORE_ID=your_default_store_id

Or set environment variables directly:

export BTCPAY_BASE_URL=https://your-btcpay-instance.com
export BTCPAY_API_KEY=your_api_key_here
export BTCPAY_STORE_ID=your_default_store_id

Usage

Running the MCP Server

npm start

For development:

npm run dev

Development and Debugging

Using MCP Inspector: The MCP Inspector provides a visual interface for testing:

# Build the project
npm run build

# Start the inspector with the BTCPayServer MCP Server
npx @modelcontextprotocol/inspector node dist/index.js

Development Workflow:

1. Clone the repository

2. Install dependencies: npm install

3. Start development mode: npm run build

4. Run the server: node dist/index.js

5. Test your changes using the MCP Inspector

The MCP server provides comprehensive error handling:

• Configuration Errors: Missing environment variables

• API Errors: BTCPayServer API communication issues

• Validation Errors: Invalid input parameters

• Authentication Errors: Invalid or expired API keys

All errors are properly formatted and returned with descriptive messages.

Security Considerations

1. API Key Security: Never commit API keys to version control

2. Environment Variables: Use secure environment variable management

3. Webhook Secrets: Always use webhook secrets for verification

4. HTTPS: Ensure BTCPayServer instance uses HTTPS

5. Permissions: Use principle of least privilege for API key permissions

BTCPayServer Compatibility

This MCP server is compatible with BTCPayServer v1.7.0 and later. It uses the official BTCPayServer REST API v1.
