Renderball

For your AI

Let your AI build on Renderball

Your Claude Code, Codex or Cursor writes the design. Renderball reads your brand, checks the design, renders it with motion, and opens it in an editor where you finish it and share it. Nothing to copy or paste.

Setup for one assistant, on one page: Claude · ChatGPT · Claude Code, Codex and Cursor.

1 · Create a key

On your account page, create a key. The page then shows the setup for each tool with the key already inside — one Copy button each. The key is shown once; it acts as you, so keep it private and revoke it when you stop using it.

Keys work with the $29/month plan. Sign up and subscribe first if you have not.

2 · Connect your AI

Claude Code:

claude mcp add --transport http renderball https://renderball.com/api/mcp \
  --header "Authorization: Bearer rb_live_…"

Codex:

export RENDERBALL_API_KEY=rb_live_…
codex mcp add renderball --url https://renderball.com/api/mcp --bearer-token-env-var RENDERBALL_API_KEY

Cursor, or any client that takes a JSON config:

{
  "mcpServers": {
    "renderball": {
      "url": "https://renderball.com/api/mcp",
      "headers": { "Authorization": "Bearer rb_live_…" }
    }
  }
}

3 · Ask for a design

Something like:

Use Renderball to make a 5-page deck for yourcompany.com introducing our product to a new customer:
the problem, how we solve it, what it looks like in practice, why it's different, the next step.
Write the outline and every page yourself, and give me the editor link.

Your AI creates the design with its outline and gets page 1’s brief back (our format, your brand, the rules, example pages). It writes the design one page at a time: each saved page’s reply carries the next page’s brief. When the last page is in, Renderball checks and renders the design and your AI gets the rendered pages and the editor link. It usually takes several minutes of your AI’s time and about half a minute of ours.

What your AI can do

  • create_deck — a new design from the brief, the brand and your outline; returns page 1’s brief.
  • submit_page — one page with its one-sentence direction; the reply carries the next page’s brief, and the last page renders the design. To fix a page later, send just that page.
  • get_page_brief · get_examples — one page’s full brief (for a helper writing that page), and more example pages.
  • see_deck · deck_status — the rendered pages as images, so your AI can check its own layout; whether a design is ready, with its editor link.
  • write_outline · submit_deck — change an existing design’s outline; replace a finished design’s whole file.
  • share_deck · list_decks · get_brief — a public link (only when you ask), your designs, a design’s saved brief.

Good to know

  • Your AI writes on its own plan; Renderball spends a few cents checking and rendering. Editing needs the $29/month plan.
  • Numbers are checked: anything not in your brief is flagged, never invented for you.
  • The claude.ai website’s connector menu and the ChatGPT apps menu take the sign-in address https://renderball.com/api/mcp/account: you sign in with Renderball once and every design lands in your account.
