Agents can already read your design system — that alone makes product development much faster and easier, and it also helps tremendously with design system adoption.
However, we very often see design system teams struggling with a lack of resources — one or two people holding up an entire org, constantly pulled toward new problems, with little time left to maintain the system itself.
Today it changes 🚀 — Meet Editor MCP — real write access to your design system, from whatever AI tool you already live in: Cursor, Claude, VS Code, Codex, ChatGPT.
Forget suggestions you copy-paste — agents make real edits, made through a conversation, landing in Supernova exactly as if you'd made them yourself.
Now you can automate up to 90% of the manual maintenance work, so your team can focus on what actually moves the needle.
That's one small step for mankind, one giant leap for Design System teams 🧑🚀
We at Supernova genuinely think this is one of the biggest steps we've taken toward a truly agentic design system. 👏
We ran this in early access for a while before today, and honestly? Our early users blew us away. We got tons of great feedback — which we moved on quickly — but the best part was watching teams put it to work in ways way beyond our imagination. Here are just a few of our favorite daily-maintenance use cases:
- Fully automated documentation writing
- Let your agents document properly every new components that lands in Supernova.
- Fill documentation gaps
- Find components missing usage guidelines or states, and draft the missing sections in
- Don’t worry, any docs changes is restorable thanks to our recent Page history release
- Bulk rename & deprecate
- Sweep a component rename or deprecation across every page and reference in one pass
- Sync docs after Figma imports
- Auto-draft or update documentation for new and changed components
- Consistency sweeps
- Enforce naming conventions and bring older pages in line with your current template
- Figma ↔ code property parity
- Catch when a component's Figma variants/props drift from its coded properties, and update the docs or property definitions to match
- Scheduled audits
- Catch stale pages, broken links, and undocumented components before anyone has to go looking
I see Supernova MCP as a massive time-saver after trying it in action this morning. I'm looking forward to making our design system maintenance completely agentic. Link codebases, Figma, etc. This is going to be huge!

Unified MCP URL
We wanted this to feel effortless, so there's just ONE url to connect to any design system or context:
https://mcp.supernova.io/mcp
At sign-in, pick a design system for Editor MCP, or a context for read-only MCP. We've bundled the documentation skills straight into the server, so there's nothing to install — your agent already speaks fluent Supernova.
https://mcp.supernova.io/mcpEditor MCP — launching today in public beta — is free to use. Its tools don't consume any Workspace credits today. That'll change once it graduates from Beta, and we'll give you plenty of notice before it does.
Use it as much as you possibly can while it's free.
Point it at the documentation backlog you've been putting off. Run a full audit of your design system. Try a bulk edit you'd never have attempted by hand. And then tell us what you find — your feedback during the Beta genuinely shapes what we build next.
We cannot wait to see what you do with it. Let's go! 🚀
