This tutorial covers how to add the Alby Bitcoin Payments MCP Server as a goose extension to interact with your lightning wallet, make and receive payments, list transactions, convert fiat amounts to sats, request invoices from lightning addresses, and interact with paid MCP tools (such as ones built with PaidMCP).
