✨ Super-MCP-App ✨

Your Intelligent, Native Mobile AI Assistant

A fast, sleek, and highly capable mobile AI chat application built with React Native (Expo) and Next.js, powered by Meta LLaMA 3.1 and Supabase.

🌟 Key Features

💬 Real-Time Conversational AI – Speak with an intelligent agent powered by the LLaMA 3.1 8B model via NVIDIA NIM.
📱 Native Mobile Experience – Built on React Native & Expo for smooth, native-like iOS and Android performance.
🎨 Modern Material 3 Design – Beautifully constructed interfaces with @react-native-paper utilizing customized color tokens.
📝 Markdown Support – Full rich-text rendering of AI responses, including syntax-highlighted code blocks (react-native-markdown-display).
🔄 Swipe-to-Delete – Fluid, gesture-based conversation management right from your chat list (Powered by react-native-gesture-handler).
🔐 Secure & Serverless Backend – Next.js acts as an API gateway safely routing AI requests, backed by Supabase for authentication and persistent chat storage.

🛠️ Technology Stack

App (Frontend)

Framework: React Native & Expo
Navigation: React Navigation (Bottom Tabs & Stack Navigators)
UI/Styling: React Native Paper
Gestures: React Native Gesture Handler
Markdown: React Native Markdown Display

API & Database (Backend)

API Framework: Next.js 16 (App Router)
Database & Auth: Supabase (PostgreSQL with Row-Level Security)
AI Engine: NVIDIA API (OpenAI-compatible endpoints running meta/llama-3.1-8b-instruct)

🏗️ System Architecture

The project follows a modern, decoupled architecture powered by the Model Context Protocol (MCP), connecting external tool providers securely to the AI model without exposing credentials to the mobile client.

🚀 Getting Started

Follow these steps to get the app running locally on your machine and simulator.

Prerequisites

Before you begin, ensure you have the following installed and configured:

Node.js (v18 or higher) and npm
Expo CLI
A Supabase account (for DB & Auth)
An NVIDIA NIM API Key for AI inference

1. Setup Backend

The backend utilizes Next.js App Router as a secure API Gateway.

# Navigate to the backend directory
cd backend

# Install dependencies
npm install

Create a .env file in the backend/ directory matching your configuration details:

NEXT_PUBLIC_SUPABASE_URL=your_supabase_url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_supabase_anon_key
SUPABASE_SERVICE_ROLE_KEY=your_supabase_service_role_key

# NVIDIA AI Configuration
NVIDIA_API_KEY=your_nvidia_nim_api_key
NVIDIA_BASE_URL=https://integrate.api.nvidia.com/v1

# Local Network App Configuration
NEXT_PUBLIC_API_URL=http://127.0.0.1:3000

Start the API development server:

npm run dev

2. Setup Mobile App

In the root project directory, install the Expo packages:

# Return to the root folder
cd ..

# Install app dependencies
npm install

# Start the Expo bundler
npx expo start

From the Expo terminal, press i to open the iOS Simulator or scan the QR code using the Expo Go app on your physical device.
