Stop AI hallucinating deprecated Android code. AI predicts tokens from stale data, causing legacy Nav2 or AsyncTask errors. 35% of Stack Overflow visits are now debugging AI code. AndroJack MCP is an open-source strict architectural gatekeeper. 🔥 v1.5.1 Features: Level 3 Validator: Scans code against 24 Android rules before you see it. 21 Tools: KMP, XR, M3, Maven BOMs. Zero Config: npx androjack-mcp install for Cursor & Claude. Build with verified standards.

Hey Product Hunt! 👋 I'm Vikas, the creator of AndroJack. If you use Claude, Cursor, or Windsurf for Android development, you've probably noticed a problem: the AI is confidently wrong. It generates AsyncTask, gives you legacy Navigation 2 advice, or writes XML layouts when you asked for Compose. Why? Because models predict tokens based on stale training data. They don't know that Navigation 3 went stable in Nov 2025, or that Android 16 (API 36) enforces strict resizability rules. Enter AndroJack MCP. 🤖 Instead of writing another system prompt, I built a Model Context Protocol (MCP) server. It acts as a strict architectural gatekeeper with 21 specialized tools. Before your AI writes a single line of Android code, AndroJack forces it to query the official Google ecosystem (developer.android.com, issue trackers, Maven Central) live. 🔥 Key Features in v1.5.1: Level 3 Code Validator: A loop-back linter that scans AI-generated code against 24 rules (like catching GlobalScope leaks or missing try/catch blocks) before you see it. 21 Active Tools: Covers everything from KMP and Android XR to Material 3 Expressive and Google Maven BOM syncs. Zero Cloud Config: No API keys needed. Just run npx androjack-mcp install to configure it for Cursor, Claude Desktop, VS Code, and more. We just crossed 500+ weekly downloads on npm! I’d love for you to try it on your next Compose or KMP project and let me know what you think. 🔗 Try it out: [npx androjack-mcp install] / [androjack-web.netlify.app]

Update since launch: AndroJack MCP is now live on the VS Code Marketplace to reduce friction in developer adoption.

The idea is simple if AI is writing Android code, we should also have infrastructure verifying it against real documentation.

Curious to learn how others are handling AI hallucination issues in mobile development.
