The only MCP server for BTCPay Server. While other Bitcoin MCP servers cover blockchain data and node RPC, btcpay-mcp is the first to expose full merchant payment processing — invoice creation, store management, pull payments, payment requests, Lightning operations, wallet management, webhooks, and exchange rates — to AI agents.

pip install btcpay-mcp
