You can provide this in several ways:\n\n- **Command line argument** (highest priority):\n\n ```bash\n npx @bytebase/dbhub --dsn \"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n ```\n\n- **Environment variable** (second priority):\n\n ```bash\n export DSN=\"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n npx @bytebase/dbhub\n ```\n\n- **Environment file** (third priority):\n - For development: Create `.env.local` with your DSN\n - For production: Create `.env` with your DSN\n ```\n DSN=postgres://user:password@localhost:5432/dbname?sslmode=disable\n ```\n\n> [!WARNING]\n> When running in Docker, use `host.docker.internal` instead of `localhost` to connect to databases running on your host machine. For example: `mysql://user:password@host.docker.internal:3306/dbname`\n\nDBHub supports the following database connection string formats:\n\n| Database | DSN Format | Example |\n| ---------- | --------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- |\n| MySQL | `mysql://[user]:[password]@[host]:[port]/[database]` | `mysql://user:password@localhost:3306/dbname` |\n| MariaDB | `mariadb://[user]:[password]@[host]:[port]/[database]` | `mariadb://user:password@localhost:3306/dbname` |\n| PostgreSQL | `postgres://[user]:[password]@[host]:[port]/[database]` | `postgres://user:password@localhost:5432/dbname?sslmode=disable` |\n| SQL Server | `sqlserver://[user]:[password]@[host]:[port]/[database]` | `sqlserver://user:password@localhost:1433/dbname` |\n| SQLite | `sqlite:///[path/to/file]` or `sqlite::memory:` | `sqlite:///path/to/database.db`, `sqlite:C:/Users/YourName/data/database.db (windows)` or `sqlite::memory:` |\n| Oracle | `oracle://[user]:[password]@[host]:[port]/[service_name]` | `oracle://username:password@localhost:1521/service_name` |\n\n#### SQL Server\n\nExtra query parameters:\n\n#### authentication\n\n- `authentication=azure-active-directory-access-token`. Only applicable when running from Azure. See [DefaultAzureCredential](https://learn.microsoft.com/en-us/azure/developer/javascript/sdk/authentication/credential-chains#use-defaultazurecredential-for-flexibility).\n\n### Transport\n\n- **stdio** (default) - for direct integration with tools like Claude Desktop:\n\n ```bash\n npx @bytebase/dbhub --transport stdio --dsn \"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n ```\n\n- **sse** - for browser and network clients:\n ```bash\n npx @bytebase/dbhub --transport sse --port 5678 --dsn \"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n ```\n\n### Command line options\n\n| Option | Description | Default |\n| --------- | --------------------------------------------------------------- | ---------------------------- |\n| demo | Run in demo mode with sample employee database | `false` |\n| dsn | Database connection string | Required if not in demo mode |\n| transport | Transport mode: `stdio` or `sse` | `stdio` |\n| port | HTTP server port (only applicable when using `--transport=sse`) | `8080` |\n| readonly | Restrict SQL execution to read-only operations | `false` |\n\nThe demo mode uses an in-memory SQLite database loaded with the [sample employee database](https://github.com/bytebase/dbhub/tree/main/resources/employee-sqlite) that includes tables for employees, departments, titles, salaries, department employees, and department managers. The sample database includes SQL scripts for table creation, data loading, and testing.\n\n## Development\n\n1. Install dependencies:\n\n ```bash\n pnpm install\n ```\n\n1.

guía de Cursor MCP](https://docs.cursor.com/context/model-context-protocol) y asegúrese de utilizar el modo [Agente](https://docs.cursor.com/chat/agent) .\n\n## Uso\n\n### Modo de solo lectura\n\nPuede ejecutar DHub en modo de solo lectura, lo que restringe la ejecución de consultas SQL a operaciones de solo lectura:\n\n```bash\n# Enable read-only mode\nnpx @bytebase/dbhub --readonly --dsn \"postgres://user:password@localhost:5432/dbname\"\n```\n\nEn el modo de solo lectura, únicamente se permiten [operaciones SQL de solo lectura](https://github.com/bytebase/dbhub/blob/main/src/utils/allowed-keywords.ts) .\n\nEsto proporciona una capa adicional de seguridad al conectarse a bases de datos de producción.\n\n### Configurar su conexión de base de datos\n\nPuede utilizar DHub en modo de demostración con una base de datos de empleados de muestra para realizar pruebas:\n\n```bash\nnpx @bytebase/dbhub --demo\n```\n\nPara bases de datos reales, se requiere un Nombre de Origen de la Base de Datos (DSN). Puede proporcionarlo de varias maneras:\n\n* **Argumento de línea de comando** (máxima prioridad):\n\n ```bash\n npx @bytebase/dbhub --dsn \"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n ```\n\n* **Variable de entorno** (segunda prioridad):\n\n ```bash\n export DSN=\"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n npx @bytebase/dbhub\n ```\n\n* **Expediente de entorno** (tercera prioridad):\n\n * Para desarrollo: crea `.env.local` con tu DSN\n * Para producción: crea `.env` con tu DSN GXP12\n\n> \\[!ADVERTENCIA] Al ejecutar en Docker, use `host.docker.internal` en lugar de `localhost` para conectarse a las bases de datos que se ejecutan en su equipo host. Por ejemplo: `mysql://user:password@host.docker.internal:3306/dbname`\n\nDBHub admite los siguientes formatos de cadenas de conexión de base de datos:\n\n| Base de datos | Formato DSN | Ejemplo |\n| ------------- | --------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- |\n| MySQL | `mysql://[user]:[password]@[host]:[port]/[database]` | `mysql://user:password@localhost:3306/dbname` |\n| MariaDB | `mariadb://[user]:[password]@[host]:[port]/[database]` | `mariadb://user:password@localhost:3306/dbname` |\n| PostgreSQL | `postgres://[user]:[password]@[host]:[port]/[database]` | `postgres://user:password@localhost:5432/dbname?sslmode=disable` |\n| Servidor SQL | `sqlserver://[user]:[password]@[host]:[port]/[database]` | `sqlserver://user:password@localhost:1433/dbname` |\n| SQLite | `sqlite:///[path/to/file]` o `sqlite::memory:` | `sqlite:///path/to/database.db` , `sqlite:C:/Users/YourName/data/database.db (windows)` o `sqlite::memory:` |\n| Oráculo | `oracle://[user]:[password]@[host]:[port]/[service_name]` | `oracle://username:password@localhost:1521/service_name` |\n\n#### Servidor SQL\n\nParámetros de consulta adicionales:\n\n#### autenticación\n\n* `authentication=azure-active-directory-access-token` .

クエリの実行が読み取り専用操作に制限されます。\n\n```bash\n# Enable read-only mode\nnpx @bytebase/dbhub --readonly --dsn \"postgres://user:password@localhost:5432/dbname\"\n```\n\n読み取り専用モードでは、[読み取り専用の SQL 操作](https://github.com/bytebase/dbhub/blob/main/src/utils/allowed-keywords.ts)のみが許可されます。\n\nこれにより、実稼働データベースに接続するときにセキュリティがさらに強化されます。\n\n### データベース接続を構成する\n\nテスト用にサンプル従業員データベースを使用して、DBHub をデモモードで使用できます。\n\n```bash\nnpx @bytebase/dbhub --demo\n```\n\n実際のデータベースでは、データベースソース名（DSN）が必要です。これはいくつかの方法で指定できます。\n\n* **コマンドライン引数**（最高優先度）:\n\n ```bash\n npx @bytebase/dbhub --dsn \"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n ```\n\n* **環境変数**（第2優先度）:\n\n ```bash\n export DSN=\"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n npx @bytebase/dbhub\n ```\n\n* **環境ファイル**（優先度3）:\n\n * 開発の場合: DSNで`.env.local`を作成します\n * 本番環境の場合: DSN GXP12 で`.env`を作成します。\n\n> \\[!警告] Dockerで実行する場合、ホストマシンで実行されているデータベースに接続するには、

对于生产：使用您的 DSN GXP12 创建`.env`\n\n> 警告：在 Docker 中运行时，请使用`host.docker.internal`而不是`localhost`来连接主机上运行的数据库。例如： `mysql://user:password@host.docker.internal:3306/dbname`\n\nDBHub支持以下数据库连接字符串格式：\n\n| 数据库 | DSN 格式 | 例子 |\n| ---------- | --------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- |\n| MySQL | `mysql://[user]:[password]@[host]:[port]/[database]` | `mysql://user:password@localhost:3306/dbname` |\n| MariaDB | `mariadb://[user]:[password]@[host]:[port]/[database]` | `mariadb://user:password@localhost:3306/dbname` |\n| PostgreSQL | `postgres://[user]:[password]@[host]:[port]/[database]` | `postgres://user:password@localhost:5432/dbname?sslmode=disable` |\n| SQL 服务器 | `sqlserver://[user]:[password]@[host]:[port]/[database]` | `sqlserver://user:password@localhost:1433/dbname` |\n| SQLite | `sqlite:///[path/to/file]`或`sqlite::memory:` | `sqlite:///path/to/database.db` `sqlite:C:/Users/YourName/data/database.db (windows)`或`sqlite::memory:` |\n| 甲骨文 | `oracle://[user]:[password]@[host]:[port]/[service_name]` | `oracle://username:password@localhost:1521/service_name` |\n\n#### SQL 服务器\n\n额外的查询参数：\n\n#### 验证\n\n* `authentication=azure-active-directory-access-token` 。仅适用于从 Azure 运行时。请参阅[DefaultAzureCredential](https://learn.microsoft.com/en-us/azure/developer/javascript/sdk/authentication/credential-chains#use-defaultazurecredential-for-flexibility) 。\n\n### 运输\n\n* **stdio** （默认）-用于与 Claude Desktop 等工具直接集成：\n\n ```bash\n npx @bytebase/dbhub --transport stdio --dsn \"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n ```\n\n* \\*\\*sse——\\*\\*适用于浏览器和网络客户端：\n\n ```bash\n npx @bytebase/dbhub --transport sse --port 5678 --dsn \"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n ```\n\n### 命令行选项\n\n| 选项 | 描述 | 默认 |\n| ---- | ------------------------------------ | -------------- |\n| 演示 | 使用示例员工数据库以演示模式运行 | `false` |\n| 域名系统 | 数据库连接字符串 | 如果非处于演示模式则为必填项 |\n| 运输 | 传输模式： `stdio`或`sse` | `stdio` |\n| 港口 | HTTP 服务器端口（仅在使用`--transport=sse`时适用） | `8080` |\n| 只读 | 将 SQL 执行限制为只读操作 | `false` |\n\n演示模式使用内存 SQLite 数据库，其中加载了[示例员工数据库](https://github.com/bytebase/dbhub/tree/main/resources/employee-sqlite)，其中包含员工、部门、职称、薪资、部门员工和部门经理等表格。示例数据库包含用于创建表、加载数据和测试的 SQL 脚本。\n\n## 发展\n\n1. 安装依赖项：\n\n ```bash\n pnpm install\n ```\n\n2. 以开发模式运行：\n\n ```bash\n pnpm dev\n ```\n\n3. 为生产而构建：\n\n ```bash\n pnpm build\n pnpm start --transport stdio --dsn \"postgres://user:password@localhost:5432/dbname?sslmode=disable\"\n ```\n\n### 使用[MCP Inspector](https://github.com/modelcontextprotocol/inspector)进行调试\n\n#### 标准输入输出\n\n```bash\n# PostgreSQL example\nTRANSPORT=stdio DSN=\"postgres://user:password@localhost:5432/dbname?sslmode=disable\" npx @modelcontextprotocol/inspector node /path/to/dbhub/dist/index.js\n```\n\n#### 上交所\n\n```bash\n# Start DBHub with SSE transport\npnpm dev --transport=sse --port=8080\n\n# Start the MCP Inspector in another terminal\nnpx @modelcontextprotocol/inspector\n```\n\n连接到 DBHub 服务器`/sse`端点\n\n## 贡献者\n\n##
