MCP OpenAI Image Generation Server

A Model Context Protocol (MCP) server that integrates with OpenAI's image generation API to create, edit, and stream images. Images are automatically saved to the Desktop for easy access by AI applications.

Note: This logo was generated by the MCP OpenAI Image Server itself, demonstrating the server's image generation capabilities.

Features

• Image Generation: Create images using OpenAI's GPT-Image-1 model
• Multi-turn Editing: Edit existing images using conversation history
• Streaming Support: Real-time partial image generation
• Desktop Integration: Automatic saving to ~/Desktop
• Internal Configuration: Secure API key management
• STDIO Transport: Runs over standard input/output

Installation

npm install
npm run build

Usage

    "apiKey": "sk-your-openai-api-key",
    "organization": "optional-org-id",
    "model": "gpt-4.1-mini"
  }
}
