Claude Desktop Setup

1. Find your Bun path:

   which bun
   # Usually: /Users/YOUR_USERNAME/.bun/bin/bun

2. Open Claude Desktop config:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

   • Windows: %APPDATA%\Claude\claude_desktop_config.json

3. Add the Luzia server (replace YOUR_USERNAME and your API key):

   {
     "mcpServers": {
       "luzia": {
         "command": "/Users/YOUR_USERNAME/.bun/bin/bun",
         "args": ["x", "@luziadev/mcp-server", "--stdio"],
         "env": {
           "PATH": "/Users/YOUR_USERNAME/.bun/bin:/usr/local/bin:/usr/bin:/bin",
           "LUZIA_API_KEY": "lz_your_api_key"
         }
       }
     }
   }

4. Restart Claude Desktop (Cmd+Q on macOS, then reopen)

5. Start asking questions:

   • "What's the current price of Bitcoin on Binance?"

   • "Compare ETH prices across all exchanges"

   • "Show me the top trading pairs on Coinbase"
