        "/absolute/path/to/mcp-database-server/dist/src/index.js", 
        "/path/to/your/database.db"
      ]
    },
    "sqlserver": {
      "command": "node",
      "args": [
        "/absolute/path/to/mcp-database-server/dist/src/index.js",
        "--sqlserver",
        "--server", "your-server-name",
        "--database", "your-database-name",
        "--user", "your-username",
        "--password", "your-password"
      ]
    },
    "postgresql": {
      "command": "node",
