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
formfrom 150+ 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, orai_completed? Apartialgrade means some supplied content didn't make it onto the slide — the manifest names what was dropped; never deliver apartialrender 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=coderuns your own python-pptx in a sandbox (widget/chart toolkit, theme injected, intent fields render as chrome). Code renders are linted, measured (layoutblock +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_runvalidates any payload + forecasts fidelity at $0 — or usemode=safeto validate-then-render in ONE call (renders + bills only if faithful; else a $0 report with the fix).verifytiers on code renders (lintdefault,lint+vlmadds 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).

Quick Start
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).

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/.

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. | N × $0.05 |
plan_slide | Brief → top form/variant candidates with confidence. | Free |
browse_catalog | 150+ 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. 9 built-in themes + your uploaded brand themes. | Free |
translate_deck | Translate any PPTX preserving formatting (32 languages). | $0.02/slide |
upload_asset | Logos, theme PPTX, images; purpose=pdf extracts a PDF into editable slide intents; or AI-generate an image. Theme upload (purpose=theme, base64 data) 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. | 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
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-urlmints 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.
How it compares
| SlideForge | python-pptx | Prompt-only AI decks | |
|---|---|---|---|
| Editable native .pptx | ✅ | ✅ | often images/exports |
