Since the first image models started coming out i've been testing each on making app store screenshots, hoping one would be able to handle it.
Finally, with OpenAIs gpt image 2, it was finally possible!
I made an open source library that gained some traction but not everyone had gpt image 2 API Keys (you need to be verified corp) so I decided to make it as a MCP that you can add to any agent.
It's very simple to use. When you are done coding it up, add the MCP and tell it to make screenshots. It will pull in reference image, screenshots and your theme and research the space then propose some ideas that you can approve/refine.
I also handle revisions and translations as well as app store copy.
Would love any feedback and if you run out of the free three screenshots but not ready to pay feel free to message the chat I can give you some more credits for feedback!
