Renderball tools (8, 3 write)

write = sends, deletes, buys or posts
  • create_deckwrite actionFree

    Start a new presentation from a brief, the brand as YOU know it (name, and only the colours, fonts and logo you actually have — never guess a colour) and your outline. With the outline the reply carries the WRITING BRIEF, so the whole deck is two calls: this, then submit_deck. Without an account it also returns a guest_token to pass on later calls and deck_url, the one link to give the user.

  • deck_statusFree

    Whether a submitted deck is still importing, ready (with the editor link), or failed (with the reason).

  • get_briefFree

    The writing brief for a deck whose outline is already saved.

  • list_decksFree

    The user's Renderball documents, newest first, with editor links. Needs an account (a key).

  • see_deckFree

    The deck's rendered pages as images, page 1 first — look at them for overlapping or clipped text, odd spacing or an element off its page, then fix the file and submit_deck again. Available once the deck has been submitted.

  • share_deckFree

    Turn on the public link for a deck and return it.

  • submit_deckwrite actionFree

    Send the complete deck file you wrote. Renderball checks it against the brief, repairs small slips, renders every page and opens it in the editor. Returns 'ready' with the editor_url, or 'importing' — then poll deck_status.

  • write_outlinewrite actionFree

    Save the page-by-page outline you wrote for a deck. Returns the WRITING BRIEF: the exact instructions for writing the deck file (format, brand facts, truth rules). Follow it, then call submit_deck.

Renderball for your AI

Renderball turns a deck your AI writes into a designed, animated, editable presentation. This repository holds the files that plug Renderball into the tools an AI runs in. The product itself lives at https://renderball.com.

Install

Skill — Claude Code, Codex, Cursor, Gemini CLI and any agent that reads skills:

npx skills add agarces1999/renderball-skills

Claude Code and Cowork plugin:

/plugin marketplace add agarces1999/renderball-skills /plugin install renderball@renderball

Gemini CLI extension:

gemini extensions install https://github.com/agarces1999/renderball-skills

MCP server, any client: https://renderball.com/api/mcp — setup at https://renderball.com/docs/agents. No key needed to try; a key from https://renderball.com/account lifts the guest limits.

Agent toolkit for the Vercel AI SDK, the OpenAI Agents SDK or any tool loop: the @renderball/agent-toolkit package on npm, source in packages/agent-toolkit.

No setup at all

An AI that can make web requests needs none of the above: the recipe at https://renderball.com/for-ai (also /llms.txt) is three steps, and the deck comes back as one link.
