✅ WORKING SOLUTION - Luno MCP Server for Claude Desktop

This is the definitive working solution for running the Luno MCP server with Claude Desktop.

🚀 Immediate Fix (Copy & Paste Ready)

Step 1: Update Claude Desktop Configuration

Open this file: ~/Library/Application Support/Claude/claude_desktop_config.json

Replace its contents with:

{
  "mcpServers": {
    "luno": {
      "command": "python3",
      "args": [
        "/Users/aman-asmuei/Documents/mcp/mcp-luno/src/luno_mcp_server/server.py"
      ],
      "cwd": "/Users/aman-asmuei/Documents/mcp/mcp-luno",
      "env": {
        "LUNO_API_KEY": "your_api_key_here",
        "LUNO_API_SECRET": "your_api_secret_here"
      }
    }
  }
}

Step 2: Replace API Credentials

  • Replace your_api_key_here with your actual Luno API key
  • Replace your_api_secret_here with your actual Luno API secret
  • If you don’t have API credentials, remove the entire env section for public tools only

Step 3: Restart Claude Desktop

  1. Completely quit Claude Desktop
  2. Start it again
  3. Wait for it to fully load

✅ What You’ll Get

Public Tools (No API credentials needed):

  • get_crypto_price - Get current Bitcoin, Ethereum, etc. prices in ZAR
  • get_market_overview - Get overview of all available markets

Private Tools (API credentials required):

  • get_account_balance - Get your account balances

🧪 Test It Works

After restarting Claude Desktop, try asking:

  1. “What’s the current Bitcoin price in EUR?” or “Get ETHZAR price”
  2. “Show me the market overview”
  3. “What’s my account balance?” (if you have API credentials)
  4. “Get crypto price for XBTGBP” (Bitcoin in British Pounds)
  5. “What’s the Ethereum price in ZAR?”

🔧 Why This Works

  • No external dependencies - Uses only Python standard library + httpx (which is available)
  • Standalone implementation - Doesn’t require FastMCP or other complex dependencies
  • Proper MCP protocol - Implements the Model Context Protocol correctly
  • Error handling - Provides clear error messages if something goes wrong

🔒 Security Notes

  • Your API credentials stay on your local machine
  • They’re passed as environment variables to the server
  • Never share your API credentials or commit them to version control

🐛 Troubleshooting

If it still doesn’t work:

  1. Check the file path - Make sure /Users/aman-asmuei/Documents/mcp/mcp-luno/src/sync_working_server.py exists
  2. Check JSON syntax - Use a JSON validator to verify your config file
  3. Check Python - Run python3 --version to ensure Python 3 is available
  4. Check permissions - Make sure the script is executable: chmod +x /Users/aman-asmuei/Documents/mcp/mcp-luno/src/enhanced_working_server.py
  5. Install httpx for real data - Run pip3 install httpx for live price data (optional)
