MCP Server Auth with live trading

I am having issues with authentication of MCP server when using with claude desktop . Even though I have configured my live trading API's correctly . This is the error I am getting : 
{"code":40110000,"message":"request is not authorized"} 

My tool config file : 
{
  "mcpServers": {
    "alpaca": {
      "command": "/Users/zee/alpaca-mcp-server/venv/bin/python",
      "args": [
        "/Users/zee/alpaca-mcp-server/alpaca_mcp_server.py"
      ],
      "env": {
        "ALPACA_API_KEY": "ABCDEEFGH",
        "ALPACA_SECRET_KEY": "ZYXWV"
      }
    }
  }
}

I've correctly configured based on your github documentation the values and set paper trading=False as well in .env file. 

 A curl using the same API keys works successfully : 
curl -X GET "https://api.alpaca.markets/v2/account" \
  -H "APCA-API-KEY-ID: ABCDEEF" \
  -H "APCA-API-SECRET-KEY: ZYXVW"

Have you guys disabled Live trading through MCP Server since I am able to use the same APIs for live trading?
How can I get more debug logs ?
Can you help me resolving this issue?
