Google Antigravity Setup Guide

After setup, you can operate CloudBase services directly from Google Antigravity’s AI chat.

Examples:

  • "Build a WeChat Mini Program ordering system with CloudBase" — AI scaffolds pages, creates the cloud database, writes cloud functions, and guides preview
  • "Build a reservation management system that lets users place orders and admins update status" — AI models it with CloudBase PostgreSQL, configures permissions, and wires up frontend and backend
  • "Add phone-number login to a Web app" — AI enables the auth method and integrates the CloudBase SDK

No need to switch to the Cloud console — you can do everything in Antigravity with natural language.

Prerequisites​

Before you start, make sure you have:

Node.js and a CloudBase environment ready

Node.js: Install Node.js v18.15.0 or later:

node --version

If you don’t have it installed, download it from the Node.js website.

CloudBase environment: See Create a CloudBase environment. New users can start for free.

Client

Configure your AI tool to connect with CloudBase capabilities. Supports local and hosted connection. See connection modes.

Step 1: Install / Configure CloudBase

Use project template (recommended) - Template includes MCP configuration and AI rulesView templates

Or add this configuration to .agent/rules/:

json
1{
2  "mcpServers": {
3    "cloudbase": {
4      "command": "npx",
5      "args": ["@cloudbase/cloudbase-mcp@latest"],
6      "env": {
7        "INTEGRATION_IDE": "Antigravity"
8      }
9    }
10  }
11}

Step 2: Chat with AI

Enter the following in your AI chat in order:

prompt
Install CloudBase Skills: run npx skills add tencentcloudbase/cloudbase-skills -y
Use CloudBase Skills: 帮我按照 Spec 工作流开发一个 CloudBase 新功能

Setup​

This automatically configures MCP and rule files:

npx @cloudbase/cloudbase-mcp downloadTemplate --template rules --ide antigravity

Option 2: Configure manually​

  1. Create rules directory

    Create .agent/rules/ under your project root:

    mkdir -p .agent/rules

  2. Configure MCP server

    Create .mcp.json under the project root and add:

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

  3. Add rules

    Copy CloudBase rule files into .agent/rules/.

    Rule activation methods:

    • Manual: mention via @ to load
    • Always On: always apply
    • Model Decision: model decides based on natural language
    • Glob: apply rules when file path matches a glob (e.g. .js, src/**/*.ts)

Verify​

After setup, in Antigravity’s AI chat, type:

Check if CloudBase tools are available

If successful, the AI should be able to access and use CloudBase tools.

FAQ​
