LnLink MCP Node Service

This is a Model Context Protocol (MCP) Node Service designed to facilitate interaction with LnLink nodes, which are built upon the Nostr protocol. It provides a robust interface for managing and interacting with both Lightning Network (LND/LITD) and RGB Protocol functionalities.

Features

• Nostr-based Interaction: Seamlessly connects and interacts with LnLink nodes leveraging the Nostr protocol.
• Comprehensive Lightning Network Management: Provides tools for LND/LITD operations, including:
  • Node status and information queries
  • Wallet management (initialization, unlocking, balance checks, address generation)
  • Peer and channel management (listing peers, opening/closing channels, connecting to peers)
  • Invoice creation and payment
• RGB Protocol Integration: Supports RGB Protocol functionalities for colored assets, including:
  • Service status and information queries
  • Wallet management (initialization, unlocking, balance checks, address generation)
  • UTXO management
  • Peer and channel management
  • Invoice creation and payment for RGB assets
• Command-Line Interface (CLI) Ready: Designed to be easily executed via npx as a command-line tool.

Installation

1. Node.js Requirement: Ensure you have Node.js installed (version 16 or higher recommended).
2. Clone Repository:

   git clone https://github.com/lnfi-network/lnlink-mcp-server.git
   cd lnlink-mcp-server
   

3. Install Dependencies:

   npm install
   

Building the Project

To compile TypeScript files to JavaScript, use the following command:

npm run build

This command will:

1. Compile TypeScript files using Vite.
2. Make the built JavaScript files (located in the dist/ directory) executable.

Usage

After building the project, you can start the service:

npm start

Running with npx

This service is designed to be run as an npx command. You will need to provide your Nostr private key and a sendTo public key as arguments.

Example mcpServers configuration for your client (replace placeholders with your actual keys):

{
  "mcpServers": {
    "lnlink": {
      "command": "npx",
      "args": [
        "@lnfi-network/lnlink-mcp-service@latest",
        "YOUR_NOSTR_PRIVATE_KEY_HERE",
        "YOUR_NOSTR_PUBLIC_KEY_TO_SEND_TO_HERE"
      ]
    }
  }
}

Note: For local development and testing, after running npm run build in this project, you can use yarn link (in this project's root) and then yarn link @lnfi-network/lnlink-mcp-service (in your client project's root) to use your local development version directly via npx.

Dependencies

• @modelcontextprotocol/sdk: Core SDK for Model Context Protocol interactions.
• @lnfi-network/lnlink-js-sdk: JavaScript SDK for interacting with LnLink nodes.
• zod: TypeScript-first schema validation library.
• vite: Next generation frontend tooling, used for building this service.
