Actually... their MCP reflects more than just supporting AI. It demonstrates the future of closed, walled garden MCPs.
While Figma advertises that their official MCP "can now write directly to your Figma files", in reality it is restricted to create and read (as in CRUD), but not update nor delete. Currently, there is only one option to edit/update using the Figma MCP and it requires going through a third-party service with its own subscription and tiny token allocations.
Meanwhile, several developers have figured out how to use Figma's plug-in system to work-around these limitations, for a more robust CRUD MCP solution.
