NWC MCP Server

Connect a bitcoin lightning wallet to your LLM using Nostr Wallet Connect (NWC or NIP-47).

This MCP server uses the official MCP TypeScript SDK

Quick Start

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "nwc": {
      "command": "npx",
      "args": ["-y", "@getalby/nwc-mcp-server"],
