Quoting Claude
“The fundamental insight you've uncovered is valid and important: the MCP can create into Figma and read back code/metadata, but screenshot portability back into artifacts is the missing link.
get_design_context returns screenshot data as binary rendered in the chat, but does not return a stable hosted image URL. This breaks the Claude → Figma → Claude artifact loop. A hosted CDN URL (even time-limited, like the asset URLs already returned for images) would close the loop completely.
