1 · Get an API key

Create a workspace key at Settings → Developers. It looks like saturn_sk_….

2 · Add the server

Claude Desktop or Cursor MCP config:

{
  "mcpServers": {
    "saturn": {
      "command": "npx",
      "args": ["-y", "saturn-mcp"],
      "env": { "SATURN_API_KEY": "saturn_sk_your_key" }
    }
  }
}

3 · Use it

Just ask your agent:

“Use saturn to build a landing page for my coffee subscription with a hero, pricing and a waitlist form, then give me the preview link.”

Builds run async — pass wait: true to block until done, or poll with get_status. Web by default; pass kind: "mobile" for a native Expo app.
