LABSCO SUMMARY

One tool covering generation and editing alike, with a side effect that decides where you can run it.

generateImage takes a prompt for text-to-image and adds imageBase64 for editing and style transfer, so a base image is inlined into the call rather than referenced by path or URL — worth knowing before sending anything large through it. The same call opens the result in your default browser rather than only returning the link, which assumes a desktop session rather than a headless host.

What it is

A single-call image generation and editing surface over the 4o-image API, returning a clickable link to the result and opening it in your default browser.

What you get

Text-to-image from a prompt alone, with generateImage returning a clickable link to the generated result.
Editing and style transfer on a picture you already have: generateImage also accepts imageBase64 alongside the prompt, so the base image travels inside the call itself.
The result opens in your default browser as the call completes, as well as coming back as a link.

Requirements

An API key for the 4o-image API, supplied as API_KEY.

Setup effort

One command plus a key — npx -y 4oimage-mcp, then supply credentials

See installation options

USE CASES

01

Producing an illustration from a written description

Send the prompt on its own and get back a link to the generated image, which also opens in your default browser.

generateImage

02

Restyling or editing a picture you already have

Inline the base image alongside the prompt describing the change, and get back a link to the edited result.

1 tool

Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.

`generateImage`

Generate images using the 4o-image API and automatically open the results in your browser.

This tool generates images based on your prompt and automatically opens them in your default browser, while also returning a clickable link.

The tool supports two modes:

Text-to-image - Create new images using just a text prompt
Image editing - Provide a base image and prompt for editing or style transfer

The response will include a direct link to the generated image and detailed information.
