Marwan Atef (@Marwan_3atef) reported Supernova shipping Editor MCP in public beta (free for now): after sign-in and picking a design system, one URL at mcp.supernova.io/mcp lets Cursor, Claude, and Codex edit docs, tokens, components, skills, and pipelines—not just read them. The company blog frames write access as the first real agentic design-system step beyond read-only MCP.
