Supernova MCP server

Supernova is the official remote MCP server from supernova.io. It answers at https://mcp.supernova.io/mcp over streamable HTTP and asks you to sign in with your supernova.io account before it lists its tools, so your client opens a login the first time it connects. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 24 October 2026, got the sign-in challenge, so it is up.

Access and maintain design system docs, tokens, components, skills, and contexts across any project.

Description as the publisher wrote it.

What Supernova needs before it works

A sign-in. The server refused to list its tools to an anonymous client and answered with an authentication challenge, which is how an MCP server protected by OAuth behaves. Add it with one of the setups below; the first connection opens a login for your supernova.io account, and the tools appear once you have approved it.

Does Supernova need an API key?

It needs a sign-in rather than a key you paste: the server answered with an authentication challenge, so your client runs the login when it first connects.
