Conversation too Long message after using Figma MCP

After just beginning a new chat I send the file key of a figma file to be retrieved via de MCP as a JSON.

The resulting text is long and maybe that’s the reason why it crashes. But I always get the message of “Conversation too long” and can´t advance.

The figma file isnt even that big. Is just a landing page.

I attached an image of the full convo.
