   {
     "mcpServers": {
       "etf-flow-mcp": {
         "command": "uv",
         "args": ["--directory", "/absolute/path/to/etf-flow-mcp", "run", "etf-flow-mcp"],
         "env": { "COINGLASS_API_KEY": "your_coinglass_api_key_here" }
       }
     }
   }
   

   Replace /absolute/path/to/etf-flow-mcp/cli.py with the full path to cli.py.
