Database Query Skill

通过 Evotown Database MCP Proxy 查询企业已注册数据库。Skill 不持有连接串；权限由 Evotown ACL + Proxy 校验。

前置条件

管理员在 Evotown 控制台注册数据库并配置 MCP 地址
当前员工 API Key 已被授权访问目标 connection_id
MCP Proxy 服务已启动（EVOTOWN_DB_MCP_URL，默认 http://localhost:9100）

动作

| action | 说明 | |--------|------| | list_connections | 列出当前员工可访问的数据库 | | list_tables | 列出某库的表 | | query | 执行只读 SELECT（Proxy 自动加 LIMIT，拒绝 INSERT/UPDATE/DELETE） |

示例

列出可访问数据库

json
{
  "action": "list_connections",
  "api_key": "evk_..."
}

查表

json
{
  "action": "list_tables",
  "connection_id": "crm-demo",
  "api_key": "evk_..."
}

只读查询

json
{
  "action": "query",
  "connection_id": "crm-demo",
  "sql": "SELECT id, name, amount FROM orders WHERE status = 'paid'",
  "api_key": "evk_..."
}

也可设置环境变量 EVOTOWN_EMPLOYEE_API_KEY，省略 api_key 字段。
