Cryptocurrency Daemon MCP Server (BETA)

A Model Context Protocol (MCP) server for interacting with cryptocurrency daemon RPC interfaces. This server enables AI assistants to help manage and interact with cryptocurrency nodes in a controlled manner.

⚠️ IMPORTANT SECURITY WARNING ⚠️

This software allows AI systems to interact with cryptocurrency daemons. Please read this warning carefully:

Running this MCP server gives AI systems the ability to:
- Send transactions
- Access wallet information
- Modify wallet settings
- View private data
- Execute daemon commands
Potential risks include:
- Loss of funds through unauthorized transactions
- Exposure of private information
- Unintended wallet or daemon modifications
- Potential security vulnerabilities if improperly configured
Required Safety Measures:
- Use a separate wallet with limited funds for AI interactions
- Never give access to wallets containing significant value
- Configure strict RPC permissions
- Monitor all AI interactions with the daemon
- Regular security audits of configurations
- Keep backups of all important data

This software is in BETA. Use at your own risk.

Installation

Installing via Smithery

To install Cryptocurrency Daemon Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @raw391/coin_daemon_mcp --client claude

1. Install the Package

You can install the package via npm:

npm install @raw391/coin-daemon-mcp

2. Configure Claude Desktop

To use this MCP with Claude Desktop, you'll need to modify your Claude Desktop configuration. The configuration file is located at:

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

Add the following to your configuration:

{
  "mcpServers": {
    "cryptocurrency": {
      "command": "npx",
      "args": [
      "-y",
        "@raw391/coin-daemon-mcp"
      ],
      "env": {
        "CONFIG_PATH": "path/to/your/config.json"
      }
    }
  }
}

3. Create Configuration File

Create a configuration file for your cryptocurrency daemons. Here are some example configurations:

Basic Single Daemon Configuration

{
  "daemons": [
    {
      "coinName": "zcash",
      "nickname": "zec-main",
      "rpcEndpoint": "127.0.0.1:8232",
      "rpcUser": "your-rpc-user",
      "rpcPassword": "your-rpc-password"
    }
  ]
}

Multiple Daemons Configuration

{
  "daemons": [
    {
      "coinName": "zcash",
      "nickname": "zec-main",
      "rpcEndpoint": "127.0.0.1:8232",
      "rpcUser": "zec-user",
      "rpcPassword": "zec-password"
    },
    {
      "coinName": "bitcoin",
      "nickname": "btc-main",
      "rpcEndpoint": "127.0.0.1:8332",
      "rpcUser": "btc-user",
      "rpcPassword": "btc-password"
    }
  ]
}

Advanced Configuration with Data Directory

For best security practices, you might want to also use a file system MCP to manage daemon data. Here's how to configure both together:

{
  "mcpServers": {
    "cryptocurrency": {
      "command": "npx",
      "args": [
        "-y",
        "@raw391/coin-daemon-mcp"
      ],
      "env": {
        "CONFIG_PATH": "C:/CryptoConfig/daemon-config.json"
      }
    },
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "C:/CryptoData"
      ]
    }
  }
}

4. Configure Your Cryptocurrency Daemon

Make sure your cryptocurrency daemon's configuration file (e.g., zcash.conf, bitcoin.conf) has the appropriate RPC settings:

server=1
rpcuser=your-rpc-user
rpcpassword=your-rpc-password
rpcallowip=127.0.0.1

5. Start Using the MCP

After configuration, restart Claude Desktop. You should see new tools, resources, and prompts available for:

Sending transactions
Checking balances
Managing wallets
Monitoring daemon status
Learning about cryptocurrencies
And more

MCP Features

The server provides three types of MCP capabilities:

Tools

Transaction Management
- send-coins: Send transparent transactions
- zsend-coins: Send shielded transactions (for privacy coins)
- shield-coins: Convert transparent to shielded funds
Wallet Operations
- get-balance: Check balances
- execute-command: Execute any supported RPC command
Daemon Management
- check-status: Get daemon information

Resources

Access valuable data and documentation:

Documentation Resources
- crypto://{coinType}/help: Get detailed documentation for specific cryptocurrencies
- daemon://{name}/help: Get help text specific to a daemon
Transaction History
- daemon://{name}/transactions: View recent transaction history

Prompts

Pre-built templates for common workflows:

Transaction Guidance
- send-transaction-template: Generate a guided prompt for constructing transactions
Analysis Templates
- balance-analysis: Analyze wallet balances and fund distribution
- daemon-diagnostic: Perform a health check of a daemon

Security Best Practices

Separate Wallets
- Create dedicated wallets for AI interactions
- Keep minimal funds in accessible wallets
- Use test networks for development
RPC Security
- Use strong, unique RPC credentials
- Enable only necessary RPC commands
- Restrict RPC access to localhost
- Monitor RPC logs
Data Management
- Regular wallet backups
- Secure storage of configuration files
- Monitoring of all transactions
- Regular security audits

Example Usage

Here's how Claude can help with common tasks:

Checking Status: "What's the current status of the Zcash daemon?"
Managing Balances: "What's my current balance across all addresses?"
Learning About Cryptocurrencies: "Can you explain how Zcash shielded transactions work?"
Sending Transactions: "Can you help me send 0.1 ZEC to address xxx?"

Troubleshooting

Connection Issues
- Verify daemon is running
- Check RPC credentials
- Ensure correct port numbers
- Verify localhost access
Permission Problems
- Check file permissions
- Verify RPC user rights
- Ensure correct configuration paths
Transaction Issues
- Verify sufficient funds
- Check network connectivity
- Ensure daemon is synced
