Figma → Cornerstone with AI: what workflow do you recommend while waiting for CSAI Studio?

Support
#1

Hello team,

I use Pro and Cornerstone daily for client projects, and I’ve been following the announcement of CSAI Studio (“Our Model, Your Way”—the model trained specifically on the Cornerstone framework) with great interest. I fully understand that this is a complex undertaking, and I would much prefer a robust solution over a rushed release.

In the meantime, I’d like to move forward with my workflow. My main goal is to transition more quickly from a Figma mockup to a Cornerstone layout, ideally with AI assistance (I use Claude, which has a Figma MCP connector).

My questions:

  • Is there currently an MCP server, plugin, or API (official or otherwise) that allows an external AI to read from and write to Cornerstone (elements, settings, styles)?

  • Is the JSON format for Cornerstone elements or templates documented? If so, could an AI generate a file that is directly importable into the builder?

  • What method do you recommend for getting the AI ​​to produce code “the Cornerstone way”—using Components, Parameters, global CSS classes, variables, etc.?

  • Do you have any idea—even a rough estimate—of the timeline for CSAI Studio, or is there a beta version I could join?

Any tips or insights from the community are also welcome!

Thanks in advance, and congratulations on the work done on Cornerstone.

  1. We will be releasing an MCP server for Cornerstone.

  2. We do not have the JSON format documented. However in my experience when an AI has access to a sample Cornerstone document it can usually understand it pretty easily.

  3. This is something we have tried to grapple with in our latest CSAI release. They’ll be many ways in which you’ll be able to interact with AI and Cornerstone. It’s taken a lot of work to get to this point and we look forward to your feedback.

  4. Our next release will include our CSAI changes. We hope to have this out before end of year.

Thanks for the kind words. Have a great day.

Hi @charlie,

Thanks a lot for the quick and detailed reply!

An MCP server for Cornerstone is an excellent choice; it’s exactly what was needed to seamlessly connect tools like Figma and Claude to the builder.

I’m looking forward to testing the next version of CSAI—hopefully, it arrives before the end of the year. I’ll be sure to share my feedback.

Best of luck to the whole team with the remaining work!
