An mcp server that generates images based on image prompts

This is a TypeScript-based MCP server that implements image generation using OPENAI's dall-e-3 image generation model.

Features

Tools

  • generate_image - Generate an image for given prompt
  • Takes prompt as a required parameter
  • Takes imageName as a required parameter to save the generated image in a generated-images directory on your desktop

Development

Install dependencies: 

npm install

Build the server: 

npm run build

For development with auto-rebuild: 

npm run watch

Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "command": "image-generator",
      "env": {
        "OPENAI_API_KEY": "<your-openai-api-key>"
    }
  }
}
Make sure to replace <your-openai-api-key> with your actual OPENAI Api Key.

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
