# Base Mini App Builder MCP Server
A powerful TypeScript MCP (Model Context Protocol) server that **actually builds** Base mini apps from start to finish. This isn't just documentation - it creates real, working Next.js projects with all the files you need!
## 🚀 What This MCP Actually Does
This MCP **builds real mini apps** by:
- ✅ **Creates complete Next.js projects** with all necessary files
- ✅ **Generates working code** with OnchainKit, TailwindCSS, TypeScript
- ✅ **Sets up Coinbase Developer API** integration
- ✅ **Creates Base mini app manifests** automatically
- ✅ **Provides interactive web UI** for easy configuration
- ✅ **Handles deployment** to Vercel/Netlify
- ✅ **Validates requirements** for Base featured placement
## 🛠️ MCP Tools
### Core Building Tools
1. **`create_mini_app_project`** - Creates complete Next.js project with all files
2. **`generate_manifest`** - Generates and saves Base mini app manifest
3. **`install_dependencies`** - Installs all required packages
4. **`start_development_server`** - Starts the Next.js dev server
5. **`deploy_mini_app`** - Deploys to Vercel/Netlify
6. **`validate_mini_app`** - Validates Base requirements
7. **`open_mini_app_builder`** - Opens interactive web interface
## 📋 Prerequisites
- **Node.js** 18.0.0 or higher
- **yarn** package manager
