mcp-asset-gen

npm version

This tool allows Claude to speak to OpenAI, and use gpt-image-1 to generate image assets. This can be pretty useful for game or web development, when you need to print individual assets.

Requirements

Node
An OpenAI API Key
- Note that this requires an organization, with ID verification at the moment.

Installation

Get an API KEY from the OpenAI website.
Export it in your shell as API_KEY.

export API_KEY=sk-proj-....

Then, paste this into that same shell:

jq --arg apiKey "$API_KEY" \ '.mcpServers = (.mcpServers // {}) | .mcpServers["mcp-asset-gen"] = { type: "stdio", command: "npx", args: ["mcp-asset-gen"], env: { API_KEY: $apiKey } }' ~/.claude.json > ~/.claude.tmp && mv ~/.claude.tmp ~/.claude.json

You're done! Ask Claude to generate you an image for something, and you'll see

Please provide a more specific description of what you'd like to see in the logo (colors, style, game theme, etc.) for better results. > It should look like an old school pacman machine (liek a wooden arcade machine) ⏺ mcp-asset-gen:generateImag(outputPathAbsolute: "/Users/jbrower/projects/mcp-asset-gen/arcade-logo.png", prompt: "An old school wooden arcade… (MCP) machine logo in the style of Pacman, with retro colors and pixelated elements, top-down view of the cabinet, nostalgic arcade gaming feel, vibrant colors against dark background", quality: "high", size: "1024x1024") ⎿ The image is now available at /Users/jbrower/projects/mcp-asset-gen/arcade-logo.png. ⏺ Generated arcade logo saved to /Users/jbrower/projects/mcp-asset-gen/arcade-logo.png
