### Description (declared)

# MySQL MCP Server (mysql-mcp-py)

支持 MySQL 协议的 MCP Server：连接与元数据发现、SQL 分析、安全执行（单条，DDL 不执行，写操作需确认）。

## 环境变量

### 必填（单连接）

| 变量 | 说明 |
|------|------|
| `DB_HOST` | 主机 |
| `DB_USER` | 用户名 |
| `DB_PASSWORD` | 密码 |
| `DB_PORT` | 端口，默认 3306 |
| `DB_DATABASE` | 默认库，可选 |

### 多环境（仅方式二：TEST_DB_PROFILES / UAT_DB_PROFILES / PROD_DB_PROFILES）

- **多环境只配三个变量**：`TEST_DB_PROFILES`、`UAT_DB_PROFILES`、`PROD_DB_PROFILES`，每个为 **JSON 数组** `[{},{}]`，表示该环境下的一条或多条连接。**不需**再配 `DB_HOST`/`DB_USER`/`DB_PASSWORD`。
- 每个数组项需含 `host`、`port`、`user`、`password`；可选 `database`、`description`、`databases`、`name`（子名）。
- Profile 名：`test_0`、`test_1`、`test_finance`（若该项含 `"name":"finance"`）、`uat_0`、`prod_0` 等。默认连接取 prod 下第一个（如 `prod_0`）。
- **单环境**：不设任一 `*_DB_PROFILES` 时，只配 `DB_HOST`、`DB_USER`、`DB_PASSWORD`（及可选 `DB_PORT`、`DB_DATABASE`）。

**示例（test / uat / prod 三环境）**：

```bash
TEST_DB_PROFILES='[{"host":"test-db.example.com","port":3306,"user":"t1","password":"xxx","database":"app_test","description":"测试环境","databases":["app_test"]}]'
UAT_DB_PROFILES='[{"host":"uat-db.example.com","port":3306,"user":"u1","password":"yyy","database":"app_uat","description":"UAT环境","databases":["app_uat"]}]'
PROD_DB_PROFILES='[{"host":"db.example.com","port":3306,"user":"ro","password":"zzz","database":"app","description":"生产环境","databases":["app","report"]}]'
```

测试环境多条连接时，数组里放多项即可，例如：

```bash
TEST_DB_PROFILES='[{"host":"t1","port":3306,"user":"u","password":"p","database":"app"},{"host":"t2","port":3306,"user":"u","password":"p","database":"order","name":"order"}]'
# → profile 为 test_0、test_order
```

调用时传 `connection="test_0"` 或 `connection="prod_0"` 等指定用哪条。

**让智能体根据自然语言选连接**：每项可配 `description`，`list_connections` / `db://config` 会展示，便于将用户说的「测试」「生产」映射到 profile 名。

**每个连接聚焦若干数据库**：每项可配 `databases`：**不配置** → 默认所有库；**空数组 `[]`** → 不允许任何库；**非空数组** → 仅允许这些库。

### 安全与行为

| 变量 | 默认 | 说明 |
|------|------|------|
| `DB_READ_ONLY` | false | 为 true 时仅允许 SELECT |
| `DB_MAX_SELECT_ROWS` | 10000 | SELECT 单次最大行数 |
| `DB_QUERY_TIMEOUT_SE…
