FigmaTK — Figma Toolkit

Swiss-army knife CLI for Figma Slides .deck files. Parse, inspect, modify, and rebuild presentations programmatically — no Figma API required.

Figma File Formats

Each Figma product has its own native file format:

Product	Extension	Supported
Figma Slides	.deck	✅
Figma Design	.fig	❌ not yet
Figma Jam (whiteboard)	.jam	❌ not yet
Figma Buzz	.buzz	❌ not yet
Figma Sites	.site	❌ not yet
Figma Make	.make	❌ not yet

Why native .deck?

Figma Slides lets you download presentations as .deck files and re-upload them. This is the native round-trip format. Exporting to .pptx is lossy — vectors get rasterized, fonts fall back to system defaults, layout breaks. By staying in .deck, you preserve everything exactly as Figma renders it.

FigmaTK makes this round-trip programmable. Download a .deck, modify it, re-upload. Everything stays native.

Plug in Claude Code or any coding agent and you have an AI that can read and edit Figma presentations end-to-end — without ever opening the Figma UI.

Use Cases

• AI agent for presentations — let an LLM rewrite copy, insert images, and produce a ready-to-upload .deck
• Batch-produce branded decks — start from a template, feed in data per client/project, get pixel-perfect slides out
• Inspect and audit — understand the internal structure of any .deck file
• Automate text and image placement across dozens of slides in seconds

Install

npm install -g figmatk

Node 18+. No build step. Pure ESM.

Quick Start

figmatk inspect my-presentation.deck        # node hierarchy
figmatk list-text my-presentation.deck      # all text + images per slide
figmatk list-overrides my-presentation.deck # editable fields per symbol

Claude Code / MCP Integration

FigmaTK ships as a Cowork plugin with an MCP server — Claude can manipulate .deck files directly as tool calls.

claude plugin marketplace add rcoenen/figmatk
claude plugin install figmatk

Or add manually in Claude Desktop → Settings → Developer → Edit Config:

{
  "mcpServers": {
    "figmatk": { "command": "figmatk-mcp" }
  }
}

Available MCP tools: figmatk_create_deck, figmatk_inspect, figmatk_list_text, figmatk_list_overrides, figmatk_update_text, figmatk_insert_image, figmatk_clone_slide, figmatk_remove_slide, figmatk_roundtrip.

Programmatic API

import { Deck } from 'figmatk';

const deck = await Deck.open('template.deck');
const slide = deck.slides[0];
slide.addText('Hello world', { style: 'Title' });
await deck.save('output.deck');
