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

Adds a cloud backend to an RSS reader built with Google Antigravity to enable cross-device sync using Supabase and MCP.

– Configure Supabase: create project, generate access token, and enable row-level security.
– Install MCP in Antigravity: use the one-click Supabase connector or add manual raw config for extra tools.
– Integrate TestSprite for automated testing and CI validation.
– Migrate local SQLite/Zustand state to Supabase to sync feeds, favorites, and read/unread status.

Quotes:

That’s not a bug — that’s what happens when an app doesn’t have a backend database.

MCP is a universal translator for Agentic AI.

No cloud, no sync, no backup.
