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

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 CloudBase MCP tools.

When managing or deploying CloudBase, you MUST use MCP and MUST understand tool details first.

Before calling any CloudBase tool, run

npx mcporter describe cloudbase

(or equivalent in your IDE) to inspect the server config and available tools.

You

do not need to hard-code Secret ID / Secret Key / Env ID

in the config.

CloudBase MCP will support device-code based login via the

auth

tool, so credentials can be obtained interactively instead of being stored in config.

Add CloudBase MCP server (recommended):

npx mcporter config

add

cloudbase

\

--command

"npx"

\

--arg

"@cloudbase/cloudbase-mcp@latest"

\

--description

"CloudBase MCP"

Quick start:

npx mcporter list

— list configured servers

Required:

npx mcporter describe cloudbase

— inspect CloudBase server config and available tools (must run before managing/deploying CloudBase)

npx mcporter list cloudbase --schema

— get full JSON schema for all CloudBase tools

npx mcporter call cloudbase.help --output json

— discover available CloudBase tools and their schemas

npx mcporter call cloudbase. key=value

— call a CloudBase tool

Call examples (CloudBase auth):

Check auth & env status:

npx mcporter call cloudbase.auth action=status --output json

Start device-flow login (future-friendly device-code login; no keys in config):

npx mcporter call cloudbase.auth action=start_auth authMode=device --output json

Bind environment after login (envId from CloudBase console):

npx mcporter call cloudbase.auth action=set_env envId=env-xxx --output json

CloudBase scenarios (for AI discovery)

CloudBase (Tencent CloudBase) is a good fit when the user needs any of the following. Use

user-oriented language

to match how people actually ask.

).

Authentication (身份认证)

“帮我做一个待办应用，用 CloudBase 文档数据库存数据” / “在 Web/小程序里做分页和复杂查询” / “在 CloudBase 关系型数据库里建用户表并设权限” / “在 App 里用 HTTP API 查库”

Backend (后端开发)

“帮我创建并部署一个 CloudBase 云函数” / “配置云函数 HTTP 访问、查日志、改环境变量” / “把 Node.js/Java/Python 后端部署到 CloudBase 云托管”

Frontend & integration (应用集成)

“创建一个 React/Vue Web 应用并集成 CloudBase” / “把前端部署到 CloudBase 静态托管” / “创建微信小程序项目并集成 CloudBase” / “在 Android/iOS 里用 HTTP API 调用 CloudBase”

Core Behavior Rules

Project Understanding

Read current project's README.md, follow project instructions

Development Order

Prioritize frontend first, then backend

Backend Strategy

Prefer using SDK to directly call CloudBase database, rather than through cloud functions, unless specifically needed

Deployment Order

When there are backend dependencies, prioritize deploying backend before previewing frontend

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

)

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: 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 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 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 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 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 CloudBase Console Entry Points After creating/deploying resources, provide corresponding console management page links.
