Design MCP servers integrate AI assistants with Figma, Excalidraw, and other visual tools — enabling designers and developers to inspect components, generate diagrams, extract design tokens, and bridge the gap between design and implementation. Front-end developers use Figma MCP to ask Claude about spacing values, font styles, or component structures from a design file without manually measuring each element. This category is still maturing but growing quickly as design-to-code workflows become a mainstream use case for AI assistants.
