Features

- Generate images using OpenAI's image generation models
- Edit existing images with text prompts and optional masks
- Automatically save generated images to local storage
- Optionally upload generated images to Cloudflare ImgBed
- Health check endpoint to verify server status
- Multiple ways to provide API key (env var, command line, direct)

Installation

1. Clone the repository and install dependencies:

git clone https://github.com/yourusername/openai-image-gen-mcp.git
cd openai-image-gen-mcp
npm install

2. Build the TypeScript project:

npm run build

Quick Start

1. Using the Run Script (Recommended for Production)

The easiest way to start the full-featured MCP server:

./run-with-key.sh

This script has the API key embedded and starts the MCP server with all features.

2. Using Direct API Key (For Testing)

node hardcoded-key.js

This is a simplified version with the API key directly embedded in the code.

3. Using Environment Variables

export OPENAI_API_KEY=your-api-key
./start.sh

Configuration

Claude MCP Configuration

To connect Claude to this MCP, use this configuration file:

{
  "mcpServers": {
    "openai-image-gen": {
      "command": "node",
      "args": ["/Users/jerry/openai-image-gen-mcp/build/index.js"]
    }
  }
}

⚠️ IMPORTANT: Use the full-featured compiled version (build/index.js) for production. The simplified versions are for testing and education only.

Available Tools

The MCP provides these tools to Claude:

1. oai_generate_image - Generate images from text prompts
2. oai_edit_image - Edit existing images with text prompts
3. health_check - Verify the server's health status

Example usage in Claude:

Generate an image of a sunset over mountains with a lake in the foreground.

Claude will use the appropriate MCP tool to create the image.
