Element Operations
Your AI assistant uses these tools to add, modify, and remove the shapes, text, and lines that make up each slide — or each layout. You don't call them directly — just describe what you want and your assistant handles the rest.
Every slide is made of elements — the individual pieces of content your audience sees. There are five element types you can create:
- Shape — rectangle, ellipse, diamond, triangle, arrow (pointing right), leftArrow, upArrow, downArrow, hexagon, star, pie, arc, or donut. Rectangles take an optional
cornerRadius; pie, arc and donut take angles. Shapes support text directly inside them — use thetextproperty on a shape instead of layering a separate text element on top. - Text — a standalone text block for titles, body content, captions, or any text that doesn't need a background shape.
- Line — a connector between two points, with optional arrow heads. Lines can anchor to other elements so they stay connected when elements move.
- Chart — data visualizations (bar, line, pie, scatter, and more). Placed with
elementType: "chart"like any other element, then populated withelement_update_chart. - Table — a grid of cells in a table style. Created empty with
elementType: "table",rowsandcolumns, then filled, restructured and restyled withelement_update_table.
Tables live on slides only, and a table imported from PowerPoint keeps its merged cells, cell text and table style. element_bulk_update moves, resizes or restacks a table, and element_delete, element_duplicate, element_group and slide_duplicate work on it; its cells, rows, columns and style change through element_update_table. slide_get shows its rows.
Images need a tool of their own, and a chart or a table needs a second call to fill it in — see Images, Charts and Tables. For design guidance on combining these elements, see Visual Design Techniques.
Slides or Layouts
These tools write to two surfaces. Anywhere one takes a slide id, it also takes a layout id (“layout-…”, from layout_list or layout_get), and the element lands on the deck's layout instead of on one slide. That is how your assistant adds something that should appear on every slide built from a layout — a logo, a footer rule, a side accent bar — rather than pasting it onto each slide in turn.
The tools that address an element rather than a surface — element_bulk_update, element_delete, element_group and element_ungroup — need no surface at all: they look an elementId up on both. Layout element ids are dle- prefixed and come from layout_get.
What Changes on a Layout
- New elements are decorative — they carry no
roleand they are not placeholders. Aroleyou pass is dropped and reported back underignored. - Charts are not available — layouts have no chart type. Put the chart on a slide.
- A placeholder's text is its prompt — updating
texton a placeholder sets the wording shown for that slot while it is empty — in the editor's Layouts view, and on every empty placeholder of the slides built from that layout. It is ghost text, never content. - Groups cannot span surfaces — every member must be on one slide, or on one layout.
Reading a layout
slide_get does not accept a layout id — it drops one silently rather than reporting it. Use layout_get to inspect a layout and get its element ids.
Example — Editing a Layout
// An accent bar on the layout, not on one slide.
// Every slide built on this layout shows it.
element_bulk_create({
deckId: "deck_abc123",
slideId: "layout-Qc9Wb3Xn", // a layout id, where a slide id would go
elements: [
{
elementType: "shape",
shapeType: "rectangle",
x: 0, y: 0,
width: 14, height: 720,
fillColor: "#1A1A2E"
}
]
})
// Response:
// {
// slides: [
// {
// slideId: "layout-Qc9Wb3Xn",
// surface: "layout",
// layoutName: "Title and Content",
// elementIds: ["dle-shape-Ka1bZ9mQ"]
// }
// ],
// ignored: ["role"]
// }Creating a Single Element
When you ask to “add a title to this slide” or “put a blue rectangle behind the heading,” your assistant uses element_create to place one element at a time. For adding several elements at once, the assistant will typically use element_bulk_create (below) instead.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
deckId | string | Yes | The deck ID |
slideId | string | Yes | The slide to add the element to — or a layout id (“layout-…”) to add it to the layout instead |
elementType | enum | Yes | 'shape', 'text', or 'line' |
shapeType | enum | Shapes only | 'rectangle', 'ellipse', 'diamond', 'triangle', 'arrow', 'leftArrow', 'upArrow', 'downArrow', 'hexagon', 'star', 'pie', 'arc', or 'donut'. Required when elementType is 'shape'. 'circle' is accepted as a deprecated alias for 'ellipse' |
x, y | number | Shape/Text | Position in pixels from the top-left corner of the canvas |
width, height | number | Shape/Text | Dimensions in pixels |
role | enum | No* | 'title', 'subtitle', 'body', or 'footer'. Identifies the element's purpose on the slide |
link | object | No | What a click on the element does in present mode (see Links below) |
* Always set role on text elements with semantic meaning (titles, body, etc.). Decorative shapes like accent bars or background rectangles don't need a role. See the full list of styling properties in the Common Properties Reference below.
What It Returns
elementId— the new element's ID (use this for updates and line anchors)type— the element type that was createdposition—{ x, y }in pixelssize—{ width, height }in pixelsoverflow— if the text doesn't fit, includes overflow info with suggestions for fixing it

})Creating Multiple Elements
Most of the time, your assistant builds a slide by placing several elements at once — a title, an accent bar, body text, and so on. element_bulk_create creates up to 50 elements in a single atomic call. All elements succeed or all fail — you won't end up with a half-built slide.
You can also target multiple slides at once using slideIds — the same elements are replicated on each slide. This is useful for adding consistent footers, logos, or accent bars across your entire presentation.
It is the only tool that creates charts and tables. A table takes rows and columns (1–75) and an optional box, and is created empty for element_update_table to fill.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
deckId | string | Yes | The deck ID |
slideId | string | No* | Single slide — or layout — to add elements to. Mutually exclusive with slideIds |
slideIds | string[] | No* | Multiple slides and/or layouts (up to 20). The same elements are created on each target. Mutually exclusive with slideId |
elements | array | Yes | Array of elements to create (1–50). Each element uses the same properties as element_create, plus an optional morphKey and link |
* Exactly one of slideId or slideIds must be provided.
morphKey pairs an element for a morph transition: on a slide set to morph, it glides from the element on the previous slide whose morphKey (or elementId, when it has none) matches. Copies made by slide_duplicate already carry their source's key, so set it only to pair elements that were not copied, and never give two elements on one slide the same key. See Present Mode, Builds & Transitions.
Links
link makes an element clickable in present mode, the shared viewer and an exported PowerPoint file. element_create and element_bulk_create take it on shapes, text and lines; element_bulk_update sets it on those and on images, and null removes it.
{ kind: "slide", slideId }— a click goes to that slide where the presenter left it, with the builds they had shown (none if they had not been there), and plays its transition; a link to its own slide does nothing. Take theslideId(slide-…) fromdeck_getorslide_get: a database id, a slide number or another deck's slide is refused with an error naming it{ kind: "relative", to }— a click goes to the next, previous, first or last slide of the show, worked out at the click, so it keeps working after a reorder: use it for next and back buttons.tois"next","previous","first"or"last"; anything else is refused. It lands as a slide link does, and does nothing past either end{ kind: "url", href }— a click opens an http, https or mailto address in a new tab. Any other scheme is refused, and the address is stored in canonical form (example.com/xbecomeshttps://example.com/x)- Buttons: link every piece of a button, the shape and its label, so a click anywhere on it follows the link
- Not linkable: charts, layout elements, and a trigger, whose click plays its reveals. A link on a trigger is refused, naming its reveals; move them with
slide_set_build_sequencefirst - Reading it back:
slide_getmarks a linked element· link → slide-…,· link → next slide(orprevious slide,first slide,last slide) or· link → https://…, and· link → deleted slideonce its slide is gone; such a link does nothing until the slide is restored
What It Returns
slides— array of results grouped by slide, each containing the created elements with their IDs, types, positions, and sizes- Each element includes
overflowinfo if text doesn't fit

// Add a footer to every slide at once
element_bulk_create({

When you ask to “change the title color to white” or “make the body text bigger,” your assistant uses element_bulk_update to modify existing elements. Only the fields you provide are changed — everything else stays the same. You can update up to 50 elements across any slides in the deck in one atomic call.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
deckId | string | Yes | The deck ID |
updates | array | Yes | Array of updates (1–50). Each needs elementId plus at least one property to change |
Updatable Properties
Each update object must include elementId and at least one of these properties:
| Property | Type | Description |
|---|---|---|
x, y, width, height | number | Position and size in pixels |
rotation | number | Rotation in degrees |
opacity | number | 0–100 (fully transparent to fully opaque) |
zIndex | number | Layer order (higher values appear on top) |
fillColor, strokeColor | string | Colors as hex (e.g., '#1C2833') |
strokeWidth | number | Stroke width in points. Centered on the shape edge — doesn't affect text area |
strokeStyle | enum | 'solid', 'dashed', or 'dotted' |
shadow | enum | Shapes and images: 'soft', 'lifted', or 'none' to remove it. A fill or stroke change keeps the shadow. On an image it follows the picture's visible pixels |
text | string | Text content (supports **bold**, *italic*, - bullets, 1. numbered, <span style="color:#HEX">…</span> for one colored run) |
fontSize, fontFamily, textColor | various | Font size in points, font family name, text color as hex |
textAlign, verticalAlign | enum | 'left'/ 'center'/ 'right' and 'top'/ 'middle'/ 'bottom' |
textInsets | object | Padding inside the element: { left, top, right, bottom } in pixels |
lineSpacing, paragraphSpacing | number / object | Line spacing multiplier (default 1.0) and paragraph spacing: { before, after } in points |
role | enum | null | Set or clear the semantic role. Pass null to remove |
altText | string | Alt text for image elements |
crop | object | Image crop: { left, top, right, bottom } as percentages (0–95) |
mask | object | null | Image mask: { shapeType: "ellipse" } or { shapeType: "rectangle", cornerRadius }; null removes it |
morphKey | string | null | Morph pairing key; null clears it, so the element pairs by its own elementId |
link | object | null | What a click does in present mode (see Links above); null removes it. Not on charts or tables |
A table accepts only x, y, width, height and zIndex; any other field refuses the whole call with a table's cells, rows, columns and style change through element_update_table; element_bulk_update moves, resizes or restacks it., followed by the fields it refused (see Tables). Resizing a table scales its columns and rows and keeps its text size, and no row shrinks below its text, so the table can come out taller than asked: its result entry's size is the box it came to.
What It Returns
results— array of results, one per updated element- Each result includes
elementId,updatedFields(list of field names that changed), andoverflowinfo if applicable
Example
element_bulk_update({
deckId: "deck_abc123",
updates: [
{
elementId: "elem_002",
textColor: "#FFFFFF",
fontSize: 44,
fontFamily: "Playfair Display"
},
{
elementId: "elem_004",
text: "- Total revenue: **$5.1M**\n- Growth: +22% QoQ\n- New customers: 410",
textColor: "#F4F6F6"
},
{
elementId: "elem_001",
fillColor: "#2E4053",
width: 16
}
]
})
// Response:
// {
// results: [
// { elementId: "elem_002",
// updatedFields: ["textColor", "fontSize", "fontFamily"] },
// { elementId: "elem_004",
// updatedFields: ["text", "textColor"] },
// { elementId: "elem_001",
// updatedFields: ["fillColor", "width"] }
// ]
// }Duplicating Elements
When you say “make two more cards like this one” or “copy the logo onto slide 5,” your assistant uses element_duplicate. It copies elements exactly — rich text, gradient and picture fills, images, chart data, custom geometry and groups — onto the same slide (offset by 20px) or onto another slide in place. Layout elements copy onto layouts the same way; layout placeholders can't be duplicated. A group comes across as a new group when every member is copied. Copies land on top, and a copy of an animated element gets its own build at the end of the slide's sequence.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
deckId | string | Yes | The deck ID |
elementIds | string[] | Yes | Elements to duplicate (1-50), all on one slide or one layout |
targetSlideId | string | No | Slide or layout to place the copies on, the same kind as the source. Omit to duplicate on the source surface |
offset | object | No | { x, y } shift in pixels. Defaults to 20, 20 on the source surface and 0, 0 on another one |
What It Returns
slides— the target surface and the new elements, in the same shape aselement_bulk_createelementIdMap— which source id became which new id
Deleting an Element
When you say “remove that subtitle” or “delete the divider line,” your assistant uses element_delete to permanently remove an element from a slide. This cannot be undone, so your assistant will typically inspect the slide first with slide_get to find the right element ID.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
deckId | string | Yes | The deck ID |
elementId | string | Yes | The element to delete |
What It Returns
success— whether the deletion succeededelementId,type,slideId— confirmation of what was removed
Example
element_delete({
deckId: "deck_abc123",
elementId: "elem_003"
})
// Response:
// {
// success: true,
// elementId: "elem_003",
// type: "line",
// slideId: "slide_002"
// }Common Properties Reference
These properties can be set when creating or updating elements. Not all properties apply to all element types.
Position & Size
| Property | Type | Applies To | Description |
|---|---|---|---|
x, y | number | Shape, Text | Position in pixels from top-left |
width, height | number | Shape, Text | Dimensions in pixels |
rotation | number | All | Rotation in degrees |
opacity | number | All | 0–100 (default 100) |
Shape Styling
| Property | Type | Description |
|---|---|---|
fillColor | string | Fill color: a theme slot such as accent1, which follows later theme changes, a hex, or none |
gradientFill | object | Gradient fill for shapes, taking precedence over fillColor: { type: 'linear'|'radial', stops: [{ position, color, alpha? }, …], angle?, centerX?, centerY?, rotWithShape? }. Needs at least two stops. Picture fills are import-only and cannot be created over MCP |
cornerRadius | number | Corner radius in pixels. Rectangles only — ignored on other shape types |
startAngle, endAngle | number | Degrees 0–360, 0 at 3 o'clock, clockwise, as in PowerPoint. Required on a pie or arc; on a donut they make a partial ring. A 75% ring from the top is 270 → 180. Ignored on other shapes |
thicknessRatio | number | Donut only: ring thickness as a fraction of the radius, 0–1 (default 0.5) |
shadow | enum | Shapes and images: 'soft' lifts a card or panel off a light background, 'lifted' floats a callout or panel, 'none' removes one. Give one layer of cards a shadow, not every shape. On an image the shadow follows its visible pixels, so a cut-out on a transparent background casts its own outline; set it with element_bulk_update, since element_create_image takes none. slide_get shows an imported shadow as its values; set a preset or 'none' to change it |
strokeColor | string | Stroke color: a theme slot or a hex |
strokeWidth | number | Stroke width in points. Centered on the shape edge — doesn't affect text area or content layout |
strokeStyle | enum | 'solid', 'dashed', or 'dotted' |
Text Formatting
| Property | Type | Description |
|---|---|---|
text | string | Text content. Supports markdown: **bold**, *italic*, - bullets, 1. numbered, <span style="color:#HEX">…</span> for one colored run |
fontSize | number | Font size in points (e.g., 12 for body, 24 for headings, 36+ for titles) |
fontFamily | string | Font family name. Use util_list_fonts to discover available fonts |
textColor | string | Text color: a theme slot or a hex |
textAlign | enum | 'left', 'center', or 'right' |
verticalAlign | enum | 'top', 'middle', or 'bottom' |
textInsets | object | Padding: { left, top, right, bottom } in pixels (defaults: 9.6px horizontal, 4.8px vertical) |
lineSpacing | number | Line spacing multiplier (default 1.0 = single spacing) |
paragraphSpacing | object | { before, after } in points (default: 0) |
role | enum | Semantic role: 'title' (36–44pt), 'subtitle' (18–24pt), 'body' (14–18pt), 'footer' (10–12pt) |
Line Properties
| Property | Type | Description |
|---|---|---|
startX, startY | number | Start point in pixels (use instead of startAnchor) |
endX, endY | number | End point in pixels (use instead of endAnchor) |
startAnchor, endAnchor | object | Connect to an existing element: { type, elementId, connectionPointId } |
arrowHead | boolean | Show arrow at the end point |
arrowTail | boolean | Show arrow at the start point |
