Figma names MCP context passing as the design-systems/AI link

Figma's blog post argues that MCP servers, a protocol for passing context between tools and AI agents, are what makes design systems useful to AI rather than just documentation for humans. That's a specific mechanism worth naming, since most AI-and-design-systems talk stays at the level of vague enthusiasm. But the actual article text wasn't retrievable here, so there's no way to check how Figma says MCP context passing works in practice, what it changes for a designer's workflow, or whether the claim survives contact with a real implementation.
