✅ FINAL SOLUTION - Proper FastMCP Luno Server with mcp.run()

This is the complete working solution using the actual Luno FastMCP implementation with mcp.run().

🚀 PROPER FASTMCP CONFIG (Copy & Paste)

Replace your claude_desktop_config.json 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"
      }
    }
  }
}

File location: ~/Library/Application Support/Claude/claude_desktop_config.json

🎯 WHAT MAKES THIS PROPER

✅ Uses actual FastMCP framework - from fastmcp import FastMCP
✅ Has proper @mcp.tool() decorators - Real FastMCP tools
✅ Includes mcp.run() - Proper FastMCP server execution
✅ Real Luno API integration - Uses actual Luno client
✅ Full tool suite - All 7 Luno trading tools

📦 REQUIRED DEPENDENCIES

# Install the required dependencies
pip3 install fastmcp httpx

🛠️ COMPLETE TOOL SET

Public Tools (No API credentials needed):

  • get_crypto_price - Get real-time prices for ANY trading pair (XBTZAR, ETHEUR, XBTGBP, etc.)
  • get_market_overview - Get overview of all available markets

Private Tools (API credentials required):

  • EUR pairs: XBTEUR, ETHEUR
  • GBP pairs: XBTGBP, ETHGBP, SOLGBP
  • USD pairs: XBTUSD, ETHUSD
  • And more!

🧪 TEST THE REAL IMPLEMENTATION

Try these examples after restarting Claude Desktop:

  1. “What’s the current Bitcoin price in EUR?” (XBTEUR)
  2. “Get ETHZAR price” (Real Ethereum to ZAR price)
  3. “Show me the market overview”
  4. “What’s my account balance?” (Real balances with API credentials)
  5. “Get crypto price for SOLGBP” (Solana in British Pounds)

🔧 WHY THIS IS THE PROPER SOLUTION

FastMCP Implementation:

  • Uses the actual FastMCP framework (from fastmcp import FastMCP)
  • Proper @mcp.tool() decorators for each function
  • Includes mcp.run(transport="stdio") to start the server
  • Real async/await support for API calls

Real Luno Integration:

  • Uses actual Luno API client (LunoClient)
  • Makes real HTTP requests to Luno API
  • Returns actual price data, not demo responses
  • Full error handling for API failures

🐛 TROUBLESHOOTING

If it doesn’t work:

  1. Install dependencies: 
    pip3 install fastmcp httpx

  2. Check the file path - Make sure /Users/aman-asmuei/Documents/mcp/mcp-luno/src/luno_mcp_server/server.py exists

  3. Check JSON syntax - Validate your config file

  4. Check Python version - Requires Python 3.10+ for FastMCP

  5. Verify dependencies: 
    python3 -c "import fastmcp; import httpx; print('Dependencies OK')"

💡 ADVANTAGES OF THIS SOLUTION

✅ Real FastMCP - Uses the actual framework, not custom implementations
✅ Production Ready - Proper async handling and error management
✅ Full Feature Set - All 7 Luno tools available
✅ Multi-Currency - Supports all Luno trading pairs
✅ Real Data - Actual API calls to Luno
✅ Scalable - Proper architecture for future enhancements

🎉 SUCCESS INDICATORS

You’ll know it’s working when:

  1. ✅ Claude Desktop starts without import errors
  2. ✅ You can see all 7 Luno tools available
  3. ✅ Price queries return real, current data
  4. ✅ Multi-currency pairs work (EUR, GBP, USD, ZAR)
  5. ✅ Account balance shows real data (with API credentials)

🔒 SECURITY
