AppScreenStudio MCP Server

Add another phone to a screenshot card in the open editor. It uses the platform set's device frame and starts next to the main phone with its size, rotation, and shadow. Set imageUrl to an image URL (upload_image with type screenshot). Extra phones paint above the main phone, in the order they were added. Returns phoneId.

Remove an extra phone added with add_phone.

Set the device color of a platform set. On a HyperRealistic (threeDFrame) set the device shows only its real finishes: pass one of the set's deviceColors ids (see the snapshot); a generic color (black, white, orange, silver, space-gray, blue, purple, red, green) picks the closest real finish.

Update an extra phone added with add_phone. Takes the same phone fields as update_screenshot. The main phone is edited with update_screenshot.

Add an image layer to a card. src is an image URL, such as one from upload_image or list_library. Pass spriteCoordinate to crop one pose of a sprite sheet.

Remove an image layer from a screenshot in the open editor.

Update an image layer on a screenshot in the open editor.

Add a box layer to a card. Pass html to draw a custom card: width and height set its layout box, and every visible style goes in the html, since backgroundColor and borderRadius only style plain boxes without html. A style element stays inside the card.

Remove a box layer from a screenshot in the open editor.

Update a box layer on a card.

Generate an asset sprite with AI and save it to the account library. Spends credits. Returns imageUrl and poses like get_sprite, with a preview of each pose. Does not place it on a card.

Generate an AI background for one card. Spends credits.

Generate a mascot sprite with AI and save it to the account library. Spends credits. Returns imageUrl and poses like get_sprite, with a preview of each pose. Does not place it on a card.

Add a card to the end of a platform set. The card is not blank: the set's first three cards get the template's sample texts and phone placement (sometimes a hidden or tilted phone), and later cards copy every layer of the set's last card without its phone image. Returns the ids of those layers so you can update or remove them.

Remove a screenshot from the open editor.

Update a card and its main phone: background, phone placement and app screen, pattern, fade, or shadow. imageUrl is the app screen inside the phone (upload_image with type screenshot). The phone model is chosen per platform set with set_device.

Add a text layer to a screenshot in the open editor.

Remove a text layer from a screenshot in the open editor.

Update a text layer on a screenshot in the open editor.

Add a platform set to the open project.

Remove an extra platform set. The first set of each platform stays.

Add a Google Fonts family to the open project. Then use it as fontFamily on text layers or as font-family in card html. Built-in editor fonts need no adding.

Set or clear the project background image. Pass an empty imageUrl to clear it.

Set the template of the open project.

Update one color of the open project's template. colorId must be one of the current template's colors: minimal (bg), gradient (from, via, to), geometric (bg, circle1, circle2), wave (from, to, wave), glass (from, to), connected (bg, dots). value is a CSS color such as #22c55e.

Return one JPEG of every card in a platform set side by side, as the editor renders them. Use it to check your edits. Defaults to the first platform set.

Copy a screenshot onto another platform set.

Set the device of a platform set. iOS sets take iphone-13-pro, iphone-13-pro-max, iphone-15-pro, iphone-15-pro-max, iphone-17-pro, iphone-17-pro-max, iphone-18-pro, iphone-18-pro-max, iphone-duo, borderless-frame, ipad-pro-12, ipad-pro-13, macbook-air-13, macbook-air-15, macbook-pro-14, macbook-pro-16. Android sets take pixel-8-pro, galaxy-s24-ultra, galaxy-s26-ultra, galaxy-tab-s10, android-borderless-frame. Social sets take any of them. borderless-frame and android-borderless-frame show the screenshot without a phone frame. macbook-air-13, macbook-air-15, macbook-pro-14, macbook-pro-16 are MacBooks: HyperRealistic 3D only, the screenshot fills the display (a 16:10 Mac screenshot loses a sliver at the sides), the lid is set with foldAmount.

Duplicate a screenshot and insert the copy immediately after it.

Read one platform of the open editor. Pass platform or platformSetId to include that set's screenshots. With no argument, a project with one platform set returns that set. A project with more than one set returns the set directory and screenshotsOmitted, without screenshot bodies. Call again with platform or an id from that directory.

Search Google Fonts by family name, category, or both. usable is true when the project can already use the family: a built-in editor font or one added with add_project_font.

Switch the open editor to a language that already exists on the project.

List assets or mascots saved on this account (not screenshots or backgrounds). Items with spriteSheet true have poses, crop rectangles for add_asset spriteCoordinate. Also returns one image of up to 10 items with each id beside its picture.

Link or unlink matching text layers across platform sets.

Move a screenshot left or right within its platform set.

Rate how well these MCP tools worked for the task you just finished, from 1 to 5 stars. Call it once per task.

Enable or disable the realistic device frame on a platform set. With threeD true the frame is a 3D device model (HyperRealistic) that also takes rotationX, rotationY, and rotationZ. 3D works on every device except borderless-frame and android-borderless-frame.

Redo the last undone edit in the open editor.

Rename the open project.

Move a layer one step forward or backward among layers of the same kind. It cannot move a layer across kinds: back to front, cards always paint back divs, phones, image layers, front divs, then texts.

Report a bug, an unexpected tool result, or a suggestion about these MCP tools, when you notice one.

Set the pixel size of a platform set.

Show or hide the notch on a platform set.

Return one saved asset or mascot in the same shape as a list_library item, including spriteSheet and poses. Also returns one image of each pose with its index drawn beside it.

Enable or disable the squircle frame on a platform set.

Update App Store or Google Play listing fields for the current language. Does not generate copy. Returns the names of the fields written.

Add up to 5 languages by translating the open language with the same AI localize flow as the editor. Translates iOS and Android screenshot text and the store listing. Social screenshot text is copied unchanged. Spends credits. Does not switch the open language. Fails when the account cannot spend credits or a code is already on the project.

Undo the last edit in the open editor.

Prepare an image upload for the open project. Returns a one-time uploadUrl. POST the image as multipart form field "file" to that URL. The response JSON url is the stored image. Use it with update_screenshot imageUrl, add_asset src, set_project_background, or img src and CSS url() inside add_div or update_div html. For card images, use type asset. The link works once; if the POST fails, call this tool again. Pass base64 only when you cannot make that HTTP request.
