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"]

Using mcporter (CLI) When MCP Is Not Available

In environments that do not support MCP (e.g. moltbot) or when users are unsure how to configure MCP, use mcporter as a CLI to call MCP tools. Confirm with the user that Secret ID, Secret Key, and Env ID are set in the mcporter config.

Config: Default

./config/mcporter.json

(override with

--config

). Prefer

--output json

for machine-readable results.

{
  "mcpServers": {
    "cloudbase-mcp": {
      "description": "CloudBase MCP",
      "command": "npx",
      "args": ["@cloudbase/cloudbase-mcp@latest"],
      "env": {
        "TENCENTCLOUD_SECRETID": "<your_secret_id>",
        "TENCENTCLOUD_SECRETKEY": "<your_secret_key>",
        "CLOUDBASE_ENV_ID": "<your_env_id>"
      }
    }
  }
}

Quick start:

• mcporter list

  — list servers/tools

• mcporter list <server> --schema

  — show tool schema

• mcporter call <server.tool> key=value

  — call a tool

Call examples:

• Selector:

  mcporter call linear.list_issues team=ENG limit:5

• Function syntax:

  mcporter call "linear.create_issue(title: \"Bug\")"

• JSON payload:

  mcporter call <server.tool> --args '{"limit":5}'

Core Behavior Rules

1. Project Understanding: Read current project's README.md, follow project instructions
2. Development Order: Prioritize frontend first, then backend
3. Backend Strategy: Prefer using SDK to directly call CloudBase database, rather than through cloud functions, unless specifically needed
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
   • Web Projects: Use CloudBase Web SDK built-in authentication (refer to

     auth-web

     )
   • Mini Program Projects: Naturally login-free, get OPENID in cloud functions (refer to

     auth-wechat

     )
   • Native Apps: Use HTTP API for authentication (refer to

     http-api

     )
6. Native App Development: CloudBase SDK is NOT available for native apps, MUST use HTTP API. Only MySQL database is supported.

Deployment Workflow

When users request deployment to CloudBase:

0. Check Existing Deployment:

   • Read README.md to check for existing deployment information
   • Identify previously deployed services and their URLs
   • Determine if this is a new deployment or update to existing services

1. Backend Deployment (if applicable):

   • Only for nodejs cloud functions: deploy directly using

     createFunction

     tools
     • Criteria: function directory contains

       index.js

       with cloud function format export:

       exports.main = async (event, context) => {}

   • For other languages backend server (Java, Go, PHP, Python, Node.js): deploy to Cloud Run
   • Ensure backend code supports CORS by default
   • Prepare Dockerfile for containerized deployment
   • Use

     manageCloudRun

     tool for deployment
   • Set MinNum instances to at least 1 to reduce cold start latency

2. Frontend Deployment (if applicable):

   • After backend deployment completes, update frontend API endpoints using the returned API addresses
   • Build the frontend application
   • Deploy to CloudBase static hosting using hosting tools

3. Display Deployment URLs:

   • Show backend deployment URL (if applicable)
   • Show frontend deployment URL with trailing slash (/) in path
   • Add random query string to frontend URL to ensure CDN cache refresh

4. Update Documentation:

   • Write deployment information and service details to README.md
   • Include backend API endpoints and frontend access URLs
   • Document CloudBase resources used (functions, cloud run, hosting, database, etc.)
   • This helps with future updates and maintenance
