## What This Does

PPTX MCP is a [Model Context Protocol](https://modelcontextprotocol.io) server that lets AI assistants create, edit, and review real PowerPoint files. It produces native `.pptx` files with 32 slide types (including org charts, Gantt charts, and 8 diagram types), 12 chart types, 12 brand presets, 27 deck archetypes, and a 26-rule review engine that scores your decks across 8 categories (accessibility, brand compliance, typography, color, layout, content, narrative, whitespace) and auto-fixes design issues. The output opens in PowerPoint, Keynote, or Google Slides -- fully editable, no lock-in.

## Why Use This

- **Real editable files** -- not images, not PDFs. Native `.pptx` you can open, edit, and present.
- **32 slide types** -- title, content, charts, tables, timelines, dashboards, SWOT, funnels, card grids, org charts, Gantt charts, and more.
- **12 chart types** -- bar, line, pie, column, area, scatter, bubble, radar, doughnut, stacked bar, stacked column, combo.
- **8 diagram types** -- org chart, matrix, pyramid, Venn, waterfall, hub-spoke, cycle, Gantt.
- **Review engine** -- 26 rules across 8 categories (accessibility, brand, typography, color, layout, content, narrative, whitespace), scores decks 0-10, and auto-fixes 7 issue types.
- **Brand consistency** -- 12 built-in presets (including industry verticals) or bring your own brand config.
- **Brand extraction** -- analyze an existing `.pptx` to extract colors, fonts, and spacing as a reusable brand config.
- **Round-trip editing** -- read existing decks, modify individual slides, re-render with new branding.
- **Designer features** -- shadow presets, edge accent bars, dividers, text auto-fit, logo placement, line dash styles.
- **Deck archetypes** -- 27 templates (pitch deck, board update, consulting assessments, product launch, etc.) for intelligent slide selection.
- **Brand guide** -- generate a 13-slide PPTX with visual specimens showcasing your brand's colors, typography, spacing, and shape styles.
- **Plan cache** -- server-side caching of planned decks avoids token-limit issues. Plans return compact summaries (~1-2KB) regardless of deck size.

The `consulting` and `finance` presets include confidential markings. The `consulting`, `government`, `healthcare`, and `finance` presets include slide numbers and date footers. The `startup` preset features a left edge bar; `consulting` uses medium shadow presets; `minimal` enables dividers and text auto-fit.

Generate a brand guide PPTX for any preset with `generate_brand_guide`. Extract a brand config from an existing deck with `extract_brand`.

Use presets via CLI (`--preset executive`) or in tool calls (`brand_preset="executive"`).

### Brand from Markdown

Use the `parse_brand_guide` tool with markdown:

```markdown
# My Brand

## Colors
- primary: #002B5C
- secondary: #0066CC
- accent: #FF6B00

## Typography
- heading_font: Arial

```

### Brand from Existing Deck

Use the `extract_brand` tool to analyze a `.pptx` and extract its colors, fonts, and spacing as a reusable brand config:

```
"Extract the brand from my_deck.pptx and save it to my_brand.json"
```

## Review Engine

The review engine scores decks 0-10 with 26 rules across 8 categories. It auto-fixes deterministic issues (title casing, minimum font sizes, off-brand colors) and flags the rest for manual review.

**Content & Layout** (definition-level)

| Rule | What it checks |
|------|----------------|
| Word count | Slides exceeding max words per slide |
| Bullet count | Too many bullets on a single slide |
| Bullet length | Individual bullets that are too wordy |
| Title presence | Missing titles on non-blank slides |
| Empty slides | Slides with no content |
| Column balance | Uneven content across columns |
| Card count | Too many cards (>6) or KPIs (>8) |
| Shadow + border conflict | Thick borders combined with shadow presets |

**Narrative & Consistency** (deck-level)

| Rule | What it checks |
|------|----------------|
| Narrative flow | Missing title slide, monotonous slide types, deck length |
| Consistency | Mixed title casing across slides |
| Visual rhythm | 3+ consecutive slides of the same type |

**Spatial Validation** (PPTX-level)

| Rule | What it checks |
|------|----------------|
| Element overlap | Shapes overlapping by more than 0.05" |
| Element bounds | Shapes extending beyond slide edges |
| Element spacing | Shapes closer than 0.1" apart |
| Text overflow | Text likely overflowing its container |
| Whitespace ratio | Slide >85% covered (crowded) or <15% (sparse) |

**Accessibility**

| Rule | What it checks |
|------|----------------|
| Image alt text | Images missing alt text descriptions |
| Min font size | Text runs below brand minimum font size |
| Contrast ratio | WCAG text-to-background contrast (4.5:1 body, 3.0:1 large text) |

**Brand Compliance**

| Rule | What it checks |
|------|----------------|
| Font compliance | Fonts not in the brand font set |
| Color compliance | Colors far from the brand palette (distance >50) |
| Logo presence | Brand logo configured but missing from title slide |
| Chart brand colors | Charts present but no `chart_colors` defined |

**Typography & Color**

| Rule | What it checks |
|------|----------------|
| Font hierarchy | Title > heading > body > caption sizes not strictly decreasing |
| Font family count | More than 3 distinct font families per slide |
| Accent overuse | More than 2 elements using the accent color |
| Distinct color count | More than 5 non-neutral colors per slide |

**Auto-fix patterns** (applied by `improve_presentation`):

| Fix | Trigger |
|-----|---------|
| Split bullets to columns | >6 bullets on a content slide |
| Promote first bullet | Missing title on content slide |
| Rebalance columns | Significantly unbalanced column content |
| Remove empty slides | Slides with no content |
| Normalize title casing | Inconsistent title casing across deck |
| Bump minimum font size | Text below brand minimum |
| Snap off-brand colors | Fill colors far from brand palette |

Scoring: errors deduct 3 points, warnings 1.5, info 0.5, suggestions 0.25.

Example review output:

```
Score: 7.2/10.0
Issues: 8

  ERROR [slide 4] Slide has 95 words (max 60). Consider reducing text.
  WARN  [slide 6] Slide has 7 bullets (max 5).
  WARN  [slide 2] 3 text run(s) below minimum font size (12pt).
  WARN  [slide 5] Low contrast (2.1:1) on 'Content Box' (threshold 4.5:1).
  INFO  [slide 3] Off-brand font(s): Comic Sans MS.
  INFO  [slide 7] Accent color used on 4 elements; sparingly is preferred.
  HINT  [deck] Slides 3-5 are all content; vary layout for visual rhythm.
  HINT  [slide 1] Image missing alt text description for accessibility.
```

## Token Limit Guidance

Large presentation plans (10+ slides) can produce 13-16KB of JSON, which may exceed LLM output token limits. PPTX MCP solves this with **server-side plan caching**:

1. `plan_presentation` caches the full definition server-side and returns a **compact summary** (~1-2KB) with a `plan_id`
2. `create_from_plan` renders the cached plan to `.pptx` without transferring the full definition
3. `get_plan_slide` retrieves individual slides (~0.5-1.5KB each) for inspection

Plans are cached for 1 hour (max 50 concurrent plans). For backward compatibility, pass `return_full_json=True` to `plan_presentation` to get the full definition.

---

## Markdown Spec Format

The `parse_spec` tool accepts structured markdown that describes slide content. This lets you write presentations in markdown and convert them to `.pptx`.

```markdown
# Presentation Title
subtitle: Q4 2025 Review
author: Jane Smith

---

## Market Analysis
- Revenue grew 15% YoY
- Customer retention at 92%
- NPS improved from 54 to 67

---

## Financial Dashboard
| Metric | Value | Change |
|--------|-------|--------|
| Revenue | $14M | +15% |
| Margin | 42% | +3pp |
| Headcount | 124 | +18 |

## Key Quote
> "The best way to predict the future is to create it."
> — Peter Drucker
```

**Supported elements:** headers (`##`), bullet lists (`-`), tables (`|`), blockquotes (`>`), code blocks, and color tokens (`color: #FF6B00`). Slide types are auto-detected from content structure.
