+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## 项目概述
+
+这是一个 MCP (Model Context Protocol) 服务器,为 Claude AI 提供多数据库访问能力。支持 SQLite、SQL Server、PostgreSQL 和 MySQL。
+
+## 核心架构
+
+项目使用**适配器模式**实现多数据库支持:
+
+```
+src/index.ts (主入口)
+    ↓
+src/handlers/ (请求路由层)
+    ↓
+src/tools/ (工具实现层)
+    ↓
+src/db/ (数据库适配器层)
+```
+
+### 关键接口
+
+所有数据库适配器必须实现 `src/db/adapter.ts` 中定义的 `DbAdapter` 接口:
+- `init()` - 初始化连接
+- `close()` - 关闭连接
+- `all(query, params?)` - 执行查询返回所有结果
+- `run(query, params?)` - 执行修改操作
+- `exec(query)` - 执行多条 SQL 语句
+- `getMetadata()` - 获取数据库元数据
+- `getListTablesQuery()` - 获取列出表的查询
+- `getDescribeTableQuery(tableName)` - 获取表结构查询
+
+### 数据库适配器
+
+- `src/db/sqlite-adapter.ts` - 使用 `sqlite3` 包,参数占位符 `?`
+- `src/db/sqlserver-adapter.ts` - 使用 `mssql` 包,参数占位符自动转换为 `@param0`
+- `src/db/postgresql-adapter.ts` - 使用 `pg` 包,参数占位符自动转换为 `$1, $2`
+- `src/db/mysql-adapter.ts` - 使用 `mysql2` 包,支持 AWS IAM 认证
+
+## 开发命令
+
+```bash
+# 构建
+npm run build
+
+# 开发模式(构建+运行)
+npm run dev
+
+# 监视模式
+npm run watch
+
+# 清理构建目录
+npm run clean
+
+# 运行示例
+npm run example
+
+# 直接运行已构建的服务器
+npm run start
+```
+

+## 运行服务器
+
+```bash
+# SQLite(默认)
+node dist/src/index.js /path/to/database.db
+
+# SQL Server
+node dist/src/index.js --sqlserver --server <server> --database <db> [--user] [--password]
+
+# PostgreSQL
+node dist/src/index.js --postgresql --host <host> --database <db> [--user] [--password] [--port]
+
+# MySQL
+node dist/src/index.js --mysql --host <host> --database <db> --port <port> [--user] [--password]
+
+# MySQL with AWS IAM
+node dist/src/index.js --mysql --aws-iam-auth --host <rds> --database <db> --user <user> --aws-region <region>
+```
+
+## MCP 工具列表
+
+| 工具 | 功能 |
+|------|------|
+| `read_query` | 执行 SELECT 查询 |
+| `write_query` | 执行 INSERT/UPDATE/DELETE |
+| `create_table` | 创建新表 |
+| `alter_table` | 修改表结构 |
+| `drop_table` | 删除表(需要 confirm=true) |
+| `list_tables` | 列出所有表 |
+| `describe_table` | 获取表结构 |
+| `export_query` | 导出查询结果(CSV/JSON) |
+| `append_insight` | 添加业务洞察到备忘录 |
+| `list_insights` | 列出所有业务洞察 |
+
+## 重要约定
+
+### 日志记录
+使用 `stderr` 而不是 `stdout` 进行日志记录,避免干扰 MCP 通信:
+```typescript
+const logger = {
+  log: (...args: any[]) => console.error('[INFO]', ...args),
+  error: (...args: any[]) => console.error('[ERROR]', ...args),
+  warn: (...args: any[]) => console.error('[WARN]', ...args),
+};
+```
+
+### 错误处理
+- 所有数据库操作使用 `try-catch` 包装
+- 错误通过 `stderr` 记录
+- 使用 `formatErrorResponse()` 格式化错误响应
+
+### 参数化查询
+所有适配器都支持参数化查询以防止 SQL 注入,各数据库使用不同的占位符格式(适配器会自动转换)。
+
+### 添加新数据库支持
+如需添加新的数据库支持:
+1. 在 `src/db/` 下创建新的适配器文件实现 `DbAdapter` 接口
+2. 在 `src/db/adapter.ts` 的 `createAdapter()` 函数中添加新数据库类型
+3. 在 `src/index.ts` 中添加相应的命令行参数解析
+4. 安装对应的数据库驱动包
+
+## 参数占位符转换
+
+不同数据库使用不同的参数占位符,适配器会自动将通用的 `?` 占位符转换为各数据库特定的格式:
+
+| 数据库 | 占位符格式 | 示例 |
+|--------|------------|------|
+| SQLite | `?` | `SELECT * FROM users WHERE id = ?` |
+| SQL Server | `@param0, @param1...` | `SELECT * FROM users WHERE id = @param0` |
+| PostgreSQL | `$1, $2...` | `SELECT * FROM users WHERE id = $1` |
+| MySQL | `?` | `SELECT * FROM users WHERE id = ?` |

-## Limitations
+## 限制
 
-- For the `run` method with INSERT statements, the adapter attempts to retrieve the last inserted ID by adding a RETURNING clause. This assumes your tables have an 'id' column.
-- Complex stored procedures or PostgreSQL-specific features might require custom implementation.
+- 对于带有 INSERT 语句的 `run` 方法,适配器会尝试通过添加 RETURNING 子句来检索最后插入的 ID。这假设您的表有一个 'id' 列。
+- 复杂的存储过程或 PostgreSQL 特定功能可能需要自定义实现。

-# PostgreSQL Setup for MCP Database Server
+# MCP 数据库服务器的 PostgreSQL 设置
 
-This document describes how to set up and use the PostgreSQL adapter with the MCP Database Server.
+本文档描述了如何设置和使用 PostgreSQL 适配器与 MCP 数据库服务器。
 
-## Prerequisites
+## 前提条件
 
-1. You need to have PostgreSQL installed and running on your system or on a remote server.
-2. Ensure the pg package is installed:
+1. 您需要在系统或远程服务器上安装并运行 PostgreSQL。
+2. 确保安装了 pg 包:
 
 ```
 npm install pg
 npm install @types/pg --save-dev
 ```
 
-## Running the Server with PostgreSQL
+## 使用 PostgreSQL 运行服务器
 
-To connect to a PostgreSQL database, use the following command-line arguments:
+要连接到 PostgreSQL 数据库,请使用以下命令行参数:
 
 ```bash
-# Basic connection
+# 基本连接
 node dist/src/index.js --postgresql --host localhost --database yourdb --user postgres --password yourpassword
 
-# With custom port (default is 5432)
+# 使用自定义端口(默认为 5432)
 node dist/src/index.js --postgresql --host localhost --database yourdb --user postgres --password yourpassword --port 5433
 
-# With SSL enabled
+# 启用 SSL
 node dist/src/index.js --postgresql --host localhost --database yourdb --user postgres --password yourpassword --ssl true
 
-# With custom connection timeout (in milliseconds)
+# 使用自定义连接超时(以毫秒为单位)
 node dist/src/index.js --postgresql --host localhost --database yourdb --user postgres --password yourpassword --connection-timeout 60000
 ```
 
-## Command Line Arguments
+## 命令行参数
 
-- `--postgresql` or `--postgres`: Specifies that you want to connect to a PostgreSQL database.
-- `--host`: The hostname or IP address of the PostgreSQL server (required).
-- `--database`: The name of the database to connect to (required).
-- `--user`: The PostgreSQL user to authenticate as.
-- `--password`: The password for the PostgreSQL user.
-- `--port`: The port the PostgreSQL server is listening on (default: 5432).
-- `--ssl`: Whether to use SSL for the connection (true/false).
-- `--connection-timeout`: The connection timeout in milliseconds (default: 30000).
+- `--postgresql` 或 `--postgres`: 指定要连接到 PostgreSQL 数据库。
+- `--host`: PostgreSQL 服务器的主机名或 IP 地址(必需)。
+- `--database`: 要连接的数据库名称(必需)。
+- `--user`: 要进行身份验证的 PostgreSQL 用户。
+- `--password`: PostgreSQL 用户的密码。
+- `--port`: PostgreSQL 服务器正在侦听的端口(默认: 5432)。
+- `--ssl`: 是否对连接使用 SSL(true/false)。
+- `--connection-timeout`: 连接超时(以毫秒为单位)(默认: 30000)。
 
-## Usage from MCP Client
+## 从 MCP 客户端使用
 
-The MCP client can interact with a PostgreSQL database using the same tools that are available for SQLite and SQL Server. The server automatically translates the generic SQL queries to PostgreSQL-specific formats.
+MCP 客户端可以使用与 SQLite 和 SQL Server 可用的相同工具与 PostgreSQL 数据库交互。服务器会自动将通用 SQL 查询转换为 PostgreSQL 特定格式。
 
-## Supported Features
+## 支持的功能
 
-- Full SQL query support for SELECT, INSERT, UPDATE, and DELETE operations.
-- Table management (CREATE TABLE, ALTER TABLE, DROP TABLE).
-- Schema introspection.
-- Connection pooling for efficient database access.
-- SSL support for secure connections.
+- 完整的 SQL 查询支持,用于 SELECT、INSERT、UPDATE 和 DELETE 操作。
+- 表管理(CREATE TABLE、ALTER TABLE、DROP TABLE)。
+- 架构内省。
+- 连接池以实现高效的数据库访问。
+- SSL 支持以实现安全连接。
 
-## Examples
+## 示例
 
-### Create a Table
+### 创建表
 
 ```sql
 CREATE TABLE users (
@@ -66,46 +66,46 @@ CREATE TABLE users (
 );
 ```
 
-### Insert Data
+### 插入数据
 
 ```sql
 INSERT INTO users (username, email) VALUES ('johndoe', 'john@example.com');
 ```
 
-### Query Data
+### 查询数据
 
 ```sql
 SELECT * FROM users WHERE username = 'johndoe';
 ```
 
-## Limitations
+## 限制
 
-- For the `run` method with INSERT statements, the adapter attempts to retrieve the last inserted ID by adding a RETURNING clause. This assumes your tables have an 'id' column.
-- Complex stored procedures or PostgreSQL-specific features might require custom implementation.
+- 对于带有 INSERT 语句的 `run` 方法,适配器会尝试通过添加 RETURNING 子句来检索最后插入的 ID。这假设您的表具有 'id' 列。
+- 复杂的存储过程或 PostgreSQL 特定功能可能需要自定义实现。
 
-## Troubleshooting
+## 故障排除
 
-### Connection Issues
+### 连接问题
 
-If you're having trouble connecting to your PostgreSQL database:
+如果您在连接 PostgreSQL 数据库时遇到问题:
 
-1. Verify that PostgreSQL is running: `pg_isready -h localhost -p 5432`
-2. Check that your credentials are correct.
-3. Ensure that the database exists and the user has appropriate permissions.
-4. Check firewall settings if connecting to a remote database.
+1. 验证 PostgreSQL 正在运行: `pg_isready -h localhost -p 5432`
+2. 检查您的凭据是否正确。
+3. 确保数据库存在且用户具有适当的权限。
+4. 如果连接到远程数据库,请检查防火墙设置。
 
-### Query Errors
+### 查询错误
 
-If your queries are failing:
+如果您的查询失败:
 
-1. Check the syntax against PostgreSQL's SQL dialect.
-2. Verify table and column names.
-3. Check that the user has proper permissions for the operations.
+1. 根据 PostgreSQL 的 SQL 方言检查语法。
+2. 验证表名和列名。
+3. 检查用户是否对操作具有适当的权限。
 
-## Performance Considerations
+## 性能考虑
 
-For optimal performance:
+为了获得最佳性能:
 
-1. Use parameterized queries to prevent SQL injection and improve query caching.
-2. Consider indexing frequently queried columns.
-3. For large result sets, use LIMIT and OFFSET for pagination. 
\ No newline at end of file
+1. 使用参数化查询以防止 SQL 注入并提高查询缓存。
+2. 考虑为经常查询的列创建索引。
+3. 对于大结果集,使用 LIMIT 和 OFFSET 进行分页。

- 在 MySQL 适配器中为 INFORMATION_SCHEMA.COLUMNS 查询添加 COLUMN_COMMENT 字段
- 在 PostgreSQL 适配器中通过 pg_description 系统表获取列注释信息
- 修改 SQLite 适配器使用 pragma_table_info 并添加 comment 字段返回
- 在 SQL Server 适配器中通过 sys.extended_properties 获取列注释
- 统一所有数据库适配器返回字段结构，新增 comment 字段
- 保持现有字段映射关系不变，仅扩展功能而不破坏兼容性
