SlideForge MCP — PowerPoint slides for AI agents

SlideForge (slideforge.dev) — the deterministic PowerPoint compiler for AI agents. Typed slide intents → native, fully editable .pptx in under a second, with a fidelity manifest that states exactly what was bound verbatim. Built by Smart Data Brokers GmbH, Switzerland.

Remote MCP server + REST API. No local install, no Python environment, no python-pptx boilerplate. OAuth 2.1 for Claude Desktop & ChatGPT; API key for everything else.

Why SlideForge

• A compiler, not a generator. A slide is a typed intent: pick a form from 200+ catalog patterns (KPI dashboards, waterfalls, Gantt plans, org charts, funnels, …), put your real content in typed fields. A deterministic engine lays it out — no LLM in the render path, same input → same slide, sub-second.
• The honesty layer. Every response carries a fidelity manifest: per field, was your content bound verbatim, mixed, or ai_completed? A partial grade means some supplied content didn't make it onto the slide — the manifest names what was dropped; never deliver a partial render without telling the user what's missing. Slides with blocking defects don't bill (usable-or-free). If your agent feeds numbers into slides, this is what makes the output auditable.
• Native, editable .pptx. Real shapes and text boxes — not images, not HTML exports. Openable and editable in PowerPoint.
• Escape hatch included — under the same trust contract. mode=code runs your own python-pptx in a sandbox (widget/chart toolkit, theme injected, intent fields render as chrome). Code renders are linted, measured (layout block + presentation_ready), and provenance-checked — agents may escape the layout grammar, never the trust grammar.
• Your template, natively. Upload your company's .pptx — slides are built ON your file (theme, masters, fonts), not a color-matched imitation.
• Check for free. dry_run validates any payload + forecasts fidelity at $0 — or use mode=safe to validate-then-render in ONE call (renders + bills only if faithful; else a $0 report with the fix). verify tiers on code renders (lint default, lint+vlm adds a visual second-look). quality_profile (executive/technical/appendix) sets the readiness bar the layout is judged against — answered on any form. Free deck inspect (POST /v1/inspect) runs a deterministic quality report on any pptx.
• 97% quality parity with Gamma in our own blind side-by-side benchmark (internal instrument, not third-party).

Pricing in one breath: creating a slide 5¢ · transforming a slide 2¢ (translate, repair) · checking free. 60 free slides on signup, no subscription. slideforge.dev/pricing

Quick Start

One click, no config file:

 

VS Code (Copilot agent mode) signs you in over OAuth on first use — no key, no JSON file.

Cursor installs with an API-key placeholder: after clicking, replace sf_live_YOUR_KEY in the server's headers with a real key from the console. Cursor's own OAuth browser launch is broken as of 3.16.17, so the key is the working path there today.

Claude Code

claude mcp add --transport http slideforge https://api.slideforge.dev/mcp/

Then just ask: "Make a KPI dashboard slide: revenue $12.4M (+18% YoY), 847 new clients, NPS 62."

Optional — install the skills + bundled server config as a plugin:

/plugin marketplace add smartdatabrokers/slideforge-mcp
/plugin install slideforge@slideforge-mcp

Or copy any folder from skills/ into ~/.claude/skills/ (personal) or .claude/skills/ (project).

Claude Desktop (OAuth — no key needed)

Settings → Connectors → Add custom connector → https://api.slideforge.dev/mcp/ — sign in with Google on first use.

ChatGPT (Developer Mode)

Settings → Apps → Advanced → Developer mode → Add custom connector → https://api.slideforge.dev/mcp/ (OAuth).

Cursor / Windsurf / Codex CLI / any MCP client (API key)

{
  "mcpServers": {
    "slideforge": {
      "url": "https://api.slideforge.dev/mcp/",
      "transport": "streamable-http",
      "headers": { "Authorization": "Bearer sf_live_YOUR_KEY" }
    }
  }
}

Get a key: slideforge.dev → Console → API keys. (Codex CLI and other AGENTS.md-native tools: see AGENTS.md.)

Run it locally (stdio — for container/offline clients)

Most clients should use the hosted remote server above (no install). But if your client boots MCP servers from a container or a local stdio process, run the bundled local server. It's a thin REST client over api.slideforge.dev — it holds no engine logic; the tool schemas are baked in locally (so discovery works offline, no key) and each call forwards to the SlideForge REST API authenticated with your key.

pip install slideforge-mcp        # or: uv pip install slideforge-mcp
export SLIDEFORGE_API_KEY=sf_live_YOUR_KEY
slideforge-mcp                    # speaks MCP over stdio

Or via Docker:

docker build -t slideforge-mcp .
docker run -i -e SLIDEFORGE_API_KEY=sf_live_YOUR_KEY slideforge-mcp

Client config (stdio):

{
  "mcpServers": {
    "slideforge": {
      "command": "slideforge-mcp",
      "env": { "SLIDEFORGE_API_KEY": "sf_live_YOUR_KEY" }
    }
  }
}

Schema discovery (tools/list) needs neither a key nor network; tool calls need the key.

LangChain / LlamaIndex (agent frameworks)

No SlideForge SDK needed — both load the MCP tools directly:

pip install langchain-mcp-adapters      # or: pip install llama-index-tools-mcp

from langchain_mcp_adapters.client import MultiServerMCPClient
client = MultiServerMCPClient({"slideforge": {
    "transport": "streamable_http",
    "url": "https://api.slideforge.dev/mcp/",
    "headers": {"Authorization": f"Bearer {API_KEY}"}}})
tools = await client.get_tools()        # 7 tools, drop into any LangGraph agent

Runnable examples + the LlamaIndex equivalent: examples/. Need a key? Sign up — 60 free slides, no credit card — then grab it at console/keys.

REST (no MCP)

curl -X POST https://api.slideforge.dev/v1/render/intent \
  -H "Authorization: Bearer sf_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"form": "kpi_metrics", "headline": "Q3 at a glance",
       "data": {"metrics": [{"label": "Revenue", "value": "$12.4M", "delta": "+18% YoY"},
                             {"label": "New clients", "value": "847"},
                             {"label": "NPS", "value": "62"}]}}'

The 7 MCP tools

Tool	What it does	Cost
create_slide	ONE slide from a structured intent (form + typed fields) or a brief; mode=safe validates-then-renders in one call; mode=code for sandboxed python-pptx (verify tiers, chrome fields, patch-by-replacements). Routing controls: variant, variant_policy, allow_fabrication/allow_truncation/allow_low_confidence (honest defaults: reject at $0 rather than guess). min_font_pt sets a BINDING type floor — text grows to meet it where the box allows; content that cannot fit returns a $0 min_font_not_met error naming the size it needs. Response carries the fidelity manifest + a measured layout readiness block on diagram forms. Default themes ship topical design — a subject-informed palette + designed cover, named in the response's design note (styling: "clean" opts out; your pinned/uploaded brand theme always wins).	$0.05 (usable-or-free)
create_deck	Whole deck: slides[] of intents (code-mode slides are first-class children), parallel render, one merged .pptx, per-slide fidelity rollup + per-slide child jobs (own preview/pptx). Failed slides isolated + free; deck-level dry_run validates the whole deck at $0. Deck-level language, direction (rtl for Arabic/Hebrew — typeset right-to-left, layout unmirrored + honestly warned), imagery/imagery_tag, styling and logo_id inherit into every slide; a slide's own value wins.	N × $0.05
plan_slide	Brief → top form/variant candidates with confidence.	Free
browse_catalog	200+ patterns with per-form JSON Schemas + copy-pasteable example intents, themes, the code-mode widget toolkit. Pass an uploaded theme_id to list its branded cover/agenda/divider layouts. type=brands lists your brand kits with their versions. 9 built-in themes + your uploaded brand kits.	Free
translate_deck	Translate any PPTX preserving formatting (32 languages).	$0.02/slide
upload_asset	Logos, brand template PPTX, images; purpose=pdf extracts a PDF into editable slide intents (PowerPoint/Keynote/Google-Slides/Beamer-exported PDFs only — other sources aren't supported yet); or AI-generate an image. Brand template upload (purpose=brand — purpose=theme is the same thing under its old name, still accepted) renders NATIVE by default — decks are built on the client's own template file. Omit data on large files for an in-card drag/drop zone.	Free / $0.01/page / $0.05/image
manage_account	Balance, usage, jobs, security status, feedback, action=feedback_list to read your filed reports back, action=brand_report for a brand kit's per-token fidelity report.	Free

dry_run: true on create tools = validation + fidelity forecast at $0.

Two more tools (generate_report, manage_connections — data-driven reports from connected tools like Zoho Sprints) exist behind an enterprise gate and are not served by default.

Also on REST (for now): the Deck Doctor. POST /v1/inspect — a free deterministic Deck Quality Report for any pptx (overflow via real font metrics, content hidden behind shapes, off-canvas leftovers, WCAG contrast). POST /v1/repair — deterministic fixes, never your words, $0.02/repaired slide, free dry-run quote. Docs

Brand kits

A brand kit is your org's identity — colors, type, logo, and (optionally) an uploaded .pptx/.potx/.thmx template — stored under a slug and rendered against on every call.

• Use one: pass theme_id=<slug> to create_slide/create_deck for the kit's default version, or <slug>@<n> to pin a specific version.
• Create one: upload_asset(purpose="brand", data=<base64 .pptx/.potx/.thmx>) — decks then render NATIVE, built on your own template file. (purpose="theme" is the same path under its old name and still works.)
• Discover: browse_catalog(type="brands") lists your kits with their versions.
• Check fidelity: manage_account(action="brand_report", theme_id=<slug>) returns the per-token fidelity report for a kit.
• Export or import from a URL: full kit CRUD, DTCG tokens.json/.potx/.thmx export, and importing an identity straight from a company's domain are REST-only today — /v1/brands (not yet mirrored as MCP tools).

---

Security

• Tool result bodies are credential-free — no signed URLs in responses. Previews are embedded inline (the agent looks at the PNG directly); the .pptx downloads via header-auth (Authorization: Bearer + ownership check), not a bearer-in-URL.
• Need a shareable link instead? POST /v1/jobs/<job_id>/download-url mints a short-TTL, single-use, revocable link.
• Artifacts auto-delete 30 days after creation.
• Every download is audit-logged.
• manage_account(action=security_status) discloses the full posture in-band.

Agent skills (this repo)

Copy-in skills that teach an agent to use SlideForge well — see skills/:

Skill	Teaches
create-slide	Intent-first slide/deck creation, schema discovery, dry-run, fidelity manifest, headless preview
inspect-repair	Free Deck Quality Report on any pptx + deterministic repair
translate-pptx	Format-preserving PPTX translation
pdf-to-pptx	PDF → editable PPTX extraction

For Codex CLI / Cursor / Copilot and other AGENTS.md-native tools, AGENTS.md carries the same guidance in the portable format. CLAUDE.md imports it for Claude Code.

Headless usage (Claude Code / Codex CLI)

No inline widgets in a terminal, but the tool result already embeds the preview PNG inline — the agent reads it directly out of the response, no fetch needed. The .pptx downloads via header-auth:

curl -H "Authorization: Bearer sf_live_YOUR_KEY" \
  -o deck.pptx https://api.slideforge.dev/v1/jobs/<job_id>/pptx   # ownership-checked

To hand off a shareable link instead of the raw file, mint a single-use one: POST /v1/jobs/<job_id>/download-url — short-TTL, revocable, works once.

The self-review loop (render → view inline preview → fix → re-render) is documented in examples/claude-code.md.
