The Firebase integration in Google AI Studio now automatically sets up Firebase AI Logic and Firebase App Check for Android apps built with generative AI features, letting apps call Gemini models directly without exposing API keys using debug tokens for testing and reCAPTCHA Enterprise for production releases on Google Play.

QueryData, in Preview, is a Conversational Analytics API endpoint that generates MongoDB-compatible Query Language queries from conversational requests using context sets of query blueprints, facets, and value searches. Context sets are authored and managed in Firestore Studio and integrated via MCP Toolbox or direct API calls.
