Webcake Landing tools 23
get_generation_guideReturns the page-building conventions reference: output shape, the absolute-positioning coordinate system, event vocabulary, and the recommended workflow.list_elementsList every supported element type, grouped by category, with a one-line summary and whether it is a container (can hold children).get_elementReturns usage details for one element type, or for several via `types: [...]`: a summary, when it applies, key `specials` fields, a sparse skeleton node (the server fills omitted boilerplate), and for common types a filled example. `types` returns { elements: { [type]: details } }; `type` returns a single doc.get_page_schemaReturns the full JSON Schema (Draft 2020-12) of a Webcake page source object { page: [...], settings: {...} } for structural reference and validation.new_elementReturns a default element node for a type in the sparse authoring shape: a fresh id, seeded styles for both breakpoints, and seeded specials. properties, runtime, empty events and per-breakpoint config are omitted because the server fills them from factory defaults on validate and save.new_page_skeletonReturns an empty, complete top-level page source { page:[], popup:[], settings, options, cartConfigs } in the Webcake editor's shape. desktopWidth (960 or 1200) and mobileWidth (420 or 360) set settings.width_section, the canvas width that all element coordinates are measured in.validate_pageValidates a page source against the JSON schema and semantic rules: unique ids, dangling event targets, children only on container types, missing field_name, top-level types, and form-data bindings (duplicate field_name within one form; dangling promoId / connectedSurvey / connectedForm / set_field_value targets). Before validating it applies deterministic layout corrections (off-canvas boxes moved on-canvas, elements below wrapped text moved down) and lists them in auto_fixed. Returns errors (structural problems that block saving) and warnings (visible layout defects such as overlapping text, off-canvas bounds, or empty bands).layoutComputes on-canvas coordinates (top/left/width/height) for a group of elements on both breakpoints. Modes: 'center' (one box centered on the canvas), 'row' (N boxes in a centered horizontal row on desktop, stacked into one column on mobile), 'grid' (N uniform cells in `cols` columns, stacked on mobile), 'stack' (a vertical list down the content column). Respects the page margins (content column 80–880 on desktop and 20–400 on mobile by default). Returns one box per item in input order, plus `notes` for off-canvas or over-wide inputs. Pure computation: no credentials, no network.search_imagesSearches Pexels stock photos (API: https://www.pexels.com/api/documentation/) by short English subject queries. Each photo includes hotlinkable URLs at several sizes, a `sizes` map with each variant's pixel dimensions, `avg_color`, and the photographer's name and attribution URL; the response also includes a `size_guide` mapping slot widths to variants (hero/banner ~940–1880px → large/large2x, card ~350px → medium, avatar → tiny). `queries: [...]` runs several searches in parallel and returns { queries: { [q]: result } } — `pick:'best'` (default) keeps only the top photo per query, `pick:'all'` the full list; `query` runs a single search. Works without configuration through a shared hosted proxy; a PEXELS_API_KEY env var or x-pexels-key header uses a personal Pexels quota.get_icon_svgResolves icon-font names into inline SVG markup via the public Iconify API (https://iconify.design/docs/api/). Accepts Material Symbols refs ("ms:verified"), Font Awesome refs ("fa:chart-line"), Iconify ids ("mdi:home"), or bare names (treated as Material Symbols); underscores become hyphens, and Material Symbols resolve to the outlined variant with a filled fallback. These are the same `ms:` / `fa:` refs that ingest results report in block.icon. Returns { icons: { "<ref>": { ok, svg, iconify } } }. In Webcake an icon renders as an SVG mask on a rectangle element: the SVG goes in responsive.desktop.config.svgMask and responsive.mobile.config.svgMask (each breakpoint is read separately), the visible color comes from styles.background (the SVG's own fill is ignored), and the mask is stretched to the box (preserveAspectRatio='none'), so a square box keeps its proportions. No Webcake credentials needed.render_previewRenders a public URL to a PNG screenshot and returns it as an image. `page_id` targets a created page's preview URL (/preview/<id>); `url` targets any public page and takes precedence. full_page (default true) captures the whole scrollable page and `width` sets the viewport; `tiles:true` returns a tall page as several top-to-bottom band images (requires a self-hosted Playwright host via RENDER_SCREENSHOT_BASE, otherwise a single image is returned). Engine: Microlink's free tier by default (API: https://microlink.io/docs/api/getting-started/overview; about 50 requests/day per IP — when rate-limited the result is ok:false with HTTP 429), or a self-hosted screenshot proxy set by RENDER_SCREENSHOT_BASE / x-render-screenshot-base; MICROLINK_API_KEY / x-microlink-key raises the quota. A page published without a custom domain serves its preview for about 10 minutes after the last publish; after that the preview shows 'Preview page is expired'. Docs: https://github.com/vuluu2k/webcake-landing-mcp/blob/main/docs/tools.mdupload_imagesRe-hosts images on Webcake's CDN (statics.pancake.vn) and returns a map from each original entry to its hosted URL. Accepts up to 20 entries per call, processed in parallel, up to 200 MB each: http(s) image URLs, data:image/…;base64 URIs, and — only when the server runs locally over stdio — local file paths (absolute, ~/, file://, or Windows drive paths; rejected per entry on the remote HTTP transport). Upload target: with Webcake credentials and a resolved organization, each image is filed into that organization's media collection (the library the Webcake editor's media picker shows) and marked collection:true with its asset_id; without credentials the public CDN endpoint is used (the URL works, but the image is not in any collection: collection:false). Organization resolution: organization_id, then WEBCAKE_ORG_ID / x-webcake-org-id, then automatic selection when the account has exactly one organization; with two or more and none given, the result is ok:false with reason:'organization_required' and the organization list. dry_run defaults to false, because this only adds images to the media library and changes no page data; dry_run:true lists what would be processed without any network or filesystem access.- +11 more on the listing page
