Nano Currency MCP server

The Nano Currency MCP Server enables MCP-compatible clients and AI agents to interact with the Nano cryptocurrency network, allowing them to send Nano and retrieve account information via a Nano node's RPC interface.

Overview of Nano Currency MCP Server

This server implements the Model Context Protocol (MCP) standard to provide AI assistants with the ability to send Nano cryptocurrency and access blockchain information. Nano is a digital currency designed for fast, feeless transactions, making it efficient for peer-to-peer payments.

Available Tools

The server provides the following functionality:

• nano_send - Sends a specified amount of Nano currency
• nano_account_info - Retrieves information about a specific Nano account/address
• nano_my_account_info - Retrieves information about your predefined Nano account
• block_info - Retrieves detailed information about a specific Nano block

Installation

Prerequisites

• Node.js with NPM installed

Setup Steps

git clone https://github.com/kilkelly/nano-currency-mcp-server.git
cd nano-currency-mcp-server
npm install

Configuration

You'll need to set the following environment variables to use the Nano Currency MCP Server:

Required Environment Variables

• NANO_RPC_URL - URL for communicating with a Nano node RPC (required)
• NANO_WORK_GENERATION_URL - URL for work generation (defaults to NANO_RPC_URL if not specified)
• NANO_PRIVATE_KEY - Nano private key for signing transactions (not your wallet seed)
• NANO_MAX_SEND_AMOUNT - Maximum amount in nano/Ӿ units per transaction (default is 0.01 nano)

Using with Claude Desktop

Setting Up Claude Desktop

1. Install and run Claude Desktop
2. Open the Settings menu
3. Click the Developer tab and then Edit Config button
4. Open claude_desktop_config.json in a text editor and configure as follows:

{
  "mcpServers": {
    "nano_currency": {
      "command": "FULL_PATH_TO_NODE_EXECUTABLE",
      "args": [
        "FULL_PATH_TO_NANO_CURRENCY_JS_FILE"
      ],
      "env": {
        "NANO_RPC_URL": "YOUR_NANO_RPC_URL",
        "NANO_WORK_GENERATION_URL": "YOUR_NANO_WORK_GENERATION_URL",
        "NANO_PRIVATE_KEY": "YOUR_NANO_PRIVATE_KEY",
        "NANO_MAX_SEND_AMOUNT": "YOUR_MAX_SEND_AMOUNT"
      }      
    }    
  }
}

Configuration Notes:

• The path to node.exe should point to your Node.js installation (e.g., C:\\Program Files\\nodejs\\node.exe)
• The path to nano-currency.js should point to the file in the cloned repository
• Windows users should use double backslashes in file paths
• For security, start with a small maximum send amount and a test account with minimal funds

Using the Tools

After configuring and restarting Claude Desktop, you'll see a tools icon indicating the MCP server is available. You can then interact with Claude by asking it to:

• Send Nano to a specific address
• Check account balances
• Retrieve transaction information
• Get information about your configured account

Safety Precautions

• Always test with small amounts of Nano
• Remember that AI assistants may occasionally misinterpret requests
• Set appropriate limits using the NANO_MAX_SEND_AMOUNT environment variable
• Use a test account with minimal funds when first setting up the server

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "nano_currency" '{"command":"node","args":["nano-currency.js"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "nano_currency": {
            "command": "node",
            "args": [
                "nano-currency.js"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "nano_currency": {
            "command": "node",
            "args": [
                "nano-currency.js"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
