# MCP VTEX - Project Summary
## 📋 Overview
**MCP VTEX Server** is a comprehensive Model Context Protocol server that provides complete integration with VTEX e-commerce APIs. It enables AI assistants like Claude and Cursor to manage your entire VTEX store through natural language conversations.
## 🏗️ Architecture
### Core Components
1. **MCP Server (`src/index.ts`)**
- Implements the Model Context Protocol
- Registers 70+ tools for VTEX operations
- Handles tool invocations and responses
- Manages server lifecycle
2. **VTEX API Client (`src/vtex-client.ts`)**
- Abstraction layer over VTEX REST APIs
- Handles authentication and request formatting
- Implements error handling and retry logic
- Supports multiple API endpoints (Catalog, Pricing, Inventory, etc.)
3. **Type Definitions (`src/types.ts`)**
- Complete TypeScript interfaces for VTEX entities
- Type-safe API contracts
- Request/response type definitions
