NWC MCP Server

NWC MCP Server is an MCP server that connects large language models to Bitcoin Lightning wallets using Nostr Wallet Connect (NWC / NIP-47). Built with the official Model Context Protocol TypeScript SDK, the server allows AI agents to interact with a user's Lightning wallet to send transactions, check balances, and handle micropayments. Developers and autonomous agent builders use it to automate Lightning-based payments and integrate financial actions directly into LLM workflows. The server supports multiple transport modes, including standard input/output (STDIO) for local execution, as well as Streamable HTTP and SSE for remote endpoints. While fully functional for wallet control through an NWC connection string, the upstream maintainers note that this project is deprecated in favor of Alby MCP, which packages these NWC capabilities alongside additional Bitcoin Lightning tools.

How to install and configure NWC MCP Server

1. Obtain an NWC connection secret (nostr+walletconnect://...) from your Lightning wallet. 2. Configure your client using the @getalby/nwc-mcp-server package via npx. 3. For Claude Desktop, open claude_desktop_config.json and add the server configuration: json { "mcpServers": { "nwc": { "command": "npx", "args": ["-y", "@getalby/nwc-mcp-server"], "env": { "NWC_CONNECTION_STRING": "YOUR NWC CONNECTION STRING HERE" } } } } 4. For Goose, run goose configure, add a Command Line Extension named nwc, set the command to npx -y @getalby/nwc-mcp-server, and add the NWC_CONNECTION_STRING environment variable. 5. Restart your client to start interacting with your Lightning wallet.

What you can do with NWC MCP Server
