CloudBase Development Guidelines

💡 Recommended: MCP Installation

For enhanced CloudBase development experience, we recommend installing CloudBase MCP (Model Context Protocol).

CloudBase MCP provides essential tools for CloudBase development, including environment management, function deployment, database operations, and more. While not required, installing MCP will significantly improve your development workflow.

MCP Configuration Instructions

Most Coding Agents support project-level MCP configuration. The standard JSON configuration structure is:

{
  "mcpServers": {
    "cloudbase": {
      "command": "npx",
      "args": ["@cloudbase/cloudbase-mcp@latest"]
    }
  }
}

Project-level configuration file locations:

• Cursor: .cursor/mcp.json
• Claude Code: .mcp.json
• Windsurf: ~/.codeium/windsurf/mcp_config.json (user-level, no project-level JSON config)
• Cline: Check Cline settings for project-level MCP configuration file location
• GitHub Copilot Chat (VS Code): Check VS Code settings for MCP configuration file location

Format differences:

• Continue: Uses YAML format in .continue/mcpServers/ folder:

name: CloudBase MCP
version: 1.0.0
schema: v1
mcpServers:
  - uses: stdio
    command: npx
    args: ["@cloudbase/cloudbase-mcp@latest"]

Quick Reference

When Developing a Web Project:

1. Platform: Read the web-development skill for SDK integration, static hosting, and build configuration
2. Authentication: Read the auth-web and auth-tool skills - Use Web SDK built-in authentication
3. Database:
4. NoSQL: no-sql-web-sdk skill
5. MySQL: relational-database-web and relational-database-tool skills
6. UI Design (Recommended): Read the ui-design skill for better UI/UX design guidelines

When Developing a Mini Program Project:

1. Platform: Read the miniprogram-development skill for project structure, WeChat Developer Tools, and wx.cloud usage
2. Authentication: Read the auth-wechat skill - Naturally login-free, get OPENID in cloud functions
3. Database:
4. NoSQL: no-sql-wx-mp-sdk skill
5. MySQL: relational-database-tool skill (via tools)
6. UI Design (Recommended): Read the ui-design skill for better UI/UX design guidelines

When Developing a Native App Project (iOS/Android/Flutter/React Native/etc.):

1. ⚠️ Platform Limitation: Native apps do NOT support CloudBase SDK - Must use HTTP API
2. Required Skills:
3. http-api - HTTP API usage for all CloudBase operations
4. relational-database-tool - MySQL database operations (via tools)
5. auth-tool - Authentication configuration
6. ⚠️ Database Limitation: Only MySQL database is supported. If users need MySQL, prompt them to enable it in console: CloudBase Console - MySQL Database

Core Capabilities

1. Authentication

Authentication Methods by Platform:
- Web Projects: Use CloudBase Web SDK built-in authentication, refer to the auth-web skill
- Mini Program Projects: Naturally login-free, get wxContext.OPENID in cloud functions, refer to the auth-wechat skill
- Node.js Backend: Refer to the auth-nodejs skill

Configuration:
- When user mentions authentication requirements, read the auth-tool skill to configure authentication providers
- Check and enable required authentication methods before implementing frontend code

2. Database Operations

Web Projects:
- NoSQL Database: Refer to the no-sql-web-sdk skill
- MySQL Relational Database: Refer to the relational-database-web skill (Web) and relational-database-tool skill (Management)

Mini Program Projects:
- NoSQL Database: Refer to the no-sql-wx-mp-sdk skill
- MySQL Relational Database: Refer to the relational-database-tool skill (via tools)

3. Deployment

Static Hosting (Web):
- Use CloudBase static hosting after build completion
- Refer to the web-development skill for deployment process
- Remind users that CDN has a few minutes of cache after deployment

Backend Deployment:
- Cloud Functions: Refer to the cloud-functions skill - Runtime cannot be changed after creation, must select correct runtime initially
- CloudRun: Refer to the cloudrun-development skill - Ensure backend code supports CORS, prepare Dockerfile for container type

4. UI Design (Recommended)

For better UI/UX design, consider reading the ui-design skill which provides:
- Design thinking framework
- Frontend aesthetics guidelines
- Best practices for creating distinctive and high-quality interfaces

4. Deployment Order: When there are backend dependencies, prioritize deploying backend before previewing frontend
5. Authentication Rules: Use built-in authentication functions, distinguish authentication methods by platform
6. Web Projects: Use CloudBase Web SDK built-in authentication (refer to auth-web)
7. Mini Program Projects: Naturally login-free, get OPENID in cloud functions (refer to auth-wechat)
8. Native Apps: Use HTTP API for authentication (refer to http-api)
