1. generate_orm_code: Batch generate ORM code from database table structures
2. visit_online_templates: Browse available online templates
3. download_online_template: Download templates from remote server
4. choose_local_template: Select a local template for code generation
5. visit_local_templates: View locally available templates
6. set_user_info: Configure user information for code comments
7. get_user_info: View current user configuration

Example Usage

// Generate ORM code for multiple tables
{
  "basePackage": "com.example.project",
  "mainSourceDirectory": "/path/to/project/src/main/java",
  "tables": [
    {
      "tableName": "user_info",
      "remark": "User information table",
      "fields": [
        {
          "fieldName": "id",
          "dataType": "BIGINT",
          "remark": "User ID"
        },
        {
          "fieldName": "user_name",
          "dataType": "VARCHAR",
          "remark": "Username"
        }
      ]
    }
  ]
}

Generated Code Structure

For a table named user_info, the generator creates:

• Entity: com.example.entity.UserInfo.java
• Mapper: com.example.mapper.UserInfoMapper.java
• Repository: com.example.repository.IUserInfoRepository.java
• Service: com.example.service.IUserInfoService.java
• Controller: com.example.controller.UserInfoController.java

Type Mappings

| Database Type | Java Type | |---------------|-----------| | TINYINT, SMALLINT, INT, INTEGER | java.lang.Integer | | BIGINT | java.lang.Long | | FLOAT, DOUBLE, DECIMAL, NUMERIC | java.math.BigDecimal | | CHAR, VARCHAR, TEXT, etc. | java.lang.String | | DATE, TIME, DATETIME, TIMESTAMP | java.lang.String | | BOOLEAN, BOOL, BIT | java.lang.Boolean |

Configuration

The server stores configuration in data/config.json and supports:

• Template selection
• User information (author name and email)
• Custom template directories

Templates

Two built-in templates are available:

1. mybatis_plus: Standard MyBatis Plus template
2. 期货管理平台(无需审批): Enterprise futures management platform template

Architecture

The project follows a clean layered architecture:

• Presentation Layer: MCP tool handlers
• Application Layer: Business logic services
• Domain Layer: Core entities and repository interfaces
• Infrastructure Layer: Concrete implementations

Requirements

• Node.js >= 16.0.0
• MCP-compatible client (e.g., Claude Desktop)
