Operate Open Canvas?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal

Other MCP servers in this category from the directory index
— Return safe metadata for one page identified by its one-based number.
List design layers — List bounded safe layer projections in original z-order for one page. Text layers include bounded UTF-16 inline style runs. Use sl_layers_get_v1 to discover verified original graphic colors before recoloring.
Get design layer — Return one safe layer projection without media URLs, object keys, comments, or provenance. Text layers include bounded UTF-16 inline style runs. Still images and filled photo grid cells include verified graphicPalette status, original source-color anchors, and tonal mode when detailed artwork supports color-range replacement. Apply desired replacement HEX colors with graphicColorMap; [] resets.
List published fonts — Return a bounded page of editor font families (bundled, Google, and live published cloud) the design can apply by fontFamilyId. Walk the catalog with cursor and pageSize. Omits file URLs and object keys.
List published graphics — Return a bounded page of published stickers, frames, or graphics. Place stickers and graphics with stickerRef on add_image. Place frames with add_frame and the same stickerRef — that creates a grid whose cells are the catalog windows, not a flat image. A polaroid 4-pack is one 4-window frame such as Film Strip, Four Up, White (sticker:film/film-4up-white.webp), not a white rect plus a grid. Do not treat public CDN URLs as workspace assets.
List create-a-design formats — Return every public Create-a-design tile: id, exact designFormat.label, canvas pixels, and family. Instagram Post is one family with 4:5 (1080×1350), 3:4 (1080×1440), and Square (1080×1080). Use Square for 1:1, not Custom size. Custom size is only when no tile matches.
View live editor page — Photograph the open editor tab as a vision-safe JPEG. Default view is one page. view: "spread" photographs the flush Side-by-side strip of every page. Hidden, unmounted, or closed editors return status only — never a saved-revision export.
List assets — List bounded asset metadata from the authorized workspace.
Get asset — Return safe metadata for one asset in the authorized workspace.
List similar assets — List a bounded page of similar visible asset metadata.
List asset trash — List a bounded page of trashed asset metadata without URLs.
List asset folders — List a bounded page of asset folders in the authorized workspace.
List template library — List bounded published template summaries without documents.
