Trust in AI-generated code is falling because models are structurally incapable of verifying their own training data. In Android development, where the ecosystem moves exceptionally fast, AI memory is often twelve to eighteen months out of date.

AndroJack is an open-source MCP server that provides 20 specialized tools for Jetpack Compose, Gradle coordination, and architecture reference. It implements a "Grounding Gate" that intercepts the AI reasoning loop and forces it to verify official documentation live.

We built this after facing constant hallucinations in a high-stakes healthcare app. It is now live as version 1.3.1. We invite technical feedback on the toolset and suggestions for further grounding strategies.
