Easily Build A Database In Google Antigravity ☁️ MCP + Supabase Tutorial

How can I sync my app between my phone & computer, for free? How can I use MCP tools in Antigravity? Today's video explores both of these concepts using MCP in Antigravity + Claude to connect a Supabase backend database to my app and test with Testsprite (https://www.testsprite.com/?via=wanderloots). Google Antigravity takes AI Coding to the next level in a full IDE, letting you build apps & vibe code/AI-code assist on your desktop including access to Claude which brings heavy coding power to keep you building ✨ Model Context Protocol (MCP) is a universal translator for AI agents, giving them access to thousands of tools without having to learn a new language. Antigravity has two easy ways of setting up MCP that I'll show you with two examples today: 1) a backend database with Supabase 2) automated testing with Testsprite I use a practical example of building a backend database for my RSS reader app (that I built in this video: https://youtu.be/MAUpppfg9Go), using a hybrid workflow of: 1) Gemini (for planning) 2) Claude (for building) 3) Gemini +Testsprite 2.1 (for testing) The ease at which I can connect MCP tools (model context protocol) is incredible. It was so easy for me to set up a backend database through Supabase, without having to configure data tables or migrate with SQL. It's honestly amazing how much I've learned and built in such a short time, leveraging Gemini 3 Pro is one of the most powerful LLMs out there, especially for coding (and it's free!). Combining the context & planning power of Gemini 3 with the coding power of Claude (Sonnet 4.6 & Opus 4.6) really does streamline your building process in Antigravity.
