## 🚀 Quick Start

<div align="center">
  <a href="https://www.npmjs.com/package/@ramarivera/gpt-image-mcp"><img src="https://img.shields.io/badge/NPX-Ready-red.svg" alt="NPX Ready"></a>
</div>

<p align="center">Run this MCP server directly using NPX without installing it. <a href="https://www.npmjs.com/package/@ramarivera/gpt-image-mcp">View on npm</a>.</p>

```bash
npx -y @ramarivera/gpt-image-mcp
```

<p align="center">The <code>-y</code> flag automatically answers "yes" to any prompts that might appear during the installation process.</p>

### 🔍 Error Handling and Reporting

The MCP server includes comprehensive error handling that provides detailed information when something goes wrong. When an error occurs:

1. **Error Format**: All errors are returned with:
   - A clear error message describing what went wrong
   - The specific error code or type
   - Additional context about the error when available

2. **AI Assistant Behavior**: When using this MCP server with AI assistants:
   - The AI will always report the full error message to help with troubleshooting
   - The AI will explain the likely cause of the error in plain language
   - The AI will suggest specific steps to resolve the issue
