MCP SERVEREdit images in Photopea by instruction: open or create a document, address layers by name, set type, run adjustments and filters, and export the flattened result to a path on disk.
LABSCO SUMMARY
The layer tree is what makes the rest work: because photopea_get_layers hands back names, indices and bounds, every subsequent edit is aimed rather than guessed at. Much of the surface is destructive by design — filters, adjustments, transforms and canvas resizes all rewrite pixels with photopea_undo as the only way back — and photopea_run_script runs arbitrary ExtendScript with full access to the open document.
An automation server for the Photopea image editor, 34 tools covering documents, layers, text, shapes, selections, adjustments, filters, export and raw scripting.
Nothing to sign in to. Sources come from a local path or a URL that the machine running the server can reach, and photopea_export_image writes to a path on that same machine.
One command — claude mcp add -s user photopea -- npx -y photopea-mcp-server
USE CASES
Open the source file, change the copy that differs per size, resize the canvas, and export each version to its own path — the document stays open between exports.
Read the layer tree to find where the placeholder sits, place the logo from a URL at the size you want, nudge it into position and move it up the stack so nothing covers it.
Find the text layers by name, load the brand font from its URL if it is not already available, and rewrite the content and styling on each one.
Put the flat colour on its own fill layer so it can be recoloured or deleted later, apply the adjustment to the pixels underneath, and step back through the history if it went wrong.
Draw the selection, soften or grow its edge, fill it with a colour at a chosen blend mode and opacity on the active layer, then deselect so the next operation is not confined to it.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
photopea_add_fill_layerAdd a non-destructive solid color fill layer that covers the entire canvas. Unlike fill_selection, this creates a separate adjustment-style layer that can be toggled, recolored, or deleted without affecting other layers. Use set_layer_properties to change its opacity or blend mode.
photopea_add_gradientApply a linear gradient fill to a layer, replacing its current pixel content. The target layer must already exist — use add_layer to create one first. Colors are distributed evenly across the gradient.
photopea_add_layerAdd a new empty layer to the active document. The new layer becomes the active layer. Use this before operations that draw onto a layer, such as fill_selection or add_gradient.
photopea_add_shapeAdd a vector shape layer (rectangle or ellipse) to the active document. The shape layer becomes the active layer. Shapes are non-destructive and can be resized with transform_layer without quality loss.
photopea_add_textAdd a new text layer to the active document at the specified position. The text layer becomes the active layer. Use paragraphBounds to create a text box with word wrapping, or omit for point text. Use load_font to add custom fonts, and list_fonts to find available font names.
photopea_apply_adjustmentApply a destructive image adjustment to the active layer's pixel data. Use select_layer to target a specific layer first. Modifies pixels directly — use undo to revert if needed.
photopea_apply_filterApply a destructive filter effect to the active layer's pixel data. Use select_layer to target a specific layer first. Modifies pixels directly — use undo to revert if needed.
photopea_clear_selectionDeselect the current selection in the active document, removing the marching ants. Does not modify any pixel data. Use after fill_selection or other selection-based operations are complete.
photopea_close_documentClose the active document. Set save to true to save changes before closing. Unsaved changes are discarded if save is false. The next open document becomes active, if any.
photopea_create_documentCreate a new blank document and make it the active document. This is typically the first step in a workflow. The document opens with a Background layer. Use open_file instead to edit an existing image.
photopea_delete_layerPermanently remove a layer from the active document by name or index. The next layer in the stack becomes active after deletion. Use get_layers to see available layers before deleting.
photopea_duplicate_layerCreate a copy of a layer in the active document. The duplicate becomes the active layer and is placed above the original. Use newName to distinguish the copy from the original.
photopea_edit_textModify the content or style of an existing text layer. Only specified properties are changed — omit parameters to keep their current values. Use get_layers to find text layer names if needed.
photopea_export_imageExport the active document to a file and save it to the local filesystem. The entire document is flattened and exported in the chosen format. Use create_document or open_file to set up the document before exporting.
photopea_fill_selectionFill the current selection with a solid color on the active layer. Requires an active selection — use make_selection to create one first. Modifies pixel data on the active layer directly. Use clear_selection afterward to deselect.
photopea_get_document_infoGet metadata about the active document including name, width, height, resolution (DPI), layer count, and color mode. Returns JSON. Use this to check document dimensions before positioning layers or making selections.
photopea_get_layersGet the full layer tree of the active document as JSON. Returns an array of layer objects with name, type, index, visible, opacity, blendMode, and bounds properties. Groups contain nested children arrays. Use this to discover layer names and indices for other layer operations.
photopea_group_layersGroup multiple layers into a layer group (folder). Layers are specified by name — use get_layers to find layer names. Grouped layers can be ungrouped later with ungroup_layers.
photopea_list_fontsList available fonts in Photopea. Returns font PostScript names that can be used with add_text and edit_text.
photopea_load_fontLoad a custom font from a URL (TTF, OTF, or WOFF2) into Photopea. The font becomes available for add_text and edit_text. Use list_fonts to find the PostScript name after loading.
photopea_make_selectionCreate a pixel selection region in the active document. After creating a selection, use fill_selection to fill it with color, or clear_selection to deselect. Use type 'all' to select the entire canvas, or 'rect'/'ellipse' with bounds for a specific region.
photopea_modify_selectionModify the current active selection. Requires an existing selection created by make_selection. For expand, contract, and feather, the amount parameter specifies pixels. Invert swaps selected and unselected areas.
photopea_move_layerTranslate a layer by a relative x/y offset in pixels from its current position. Positive x moves right, positive y moves down. Use get_layers to check current layer bounds, or transform_layer for scaling and rotation.
photopea_open_fileOpen an existing image file in Photopea as a new document. Supports PSD, PNG, JPG, WebP, SVG, and other common formats. The opened file becomes the active document. Use create_document instead to start with a blank canvas.
photopea_place_imagePlace an image into the active document from a URL or local file path. Creates a new layer with the placed image as the active layer. Use width/height to resize while preserving aspect ratio, or x/y to position the layer.
photopea_redoRedo one or more previously undone actions in the active document. Only available after using undo — the redo history is cleared when new actions are performed.
photopea_reorder_layerMove a layer to a new position in the layer stack. Use 'top' or 'bottom' to move to the ends of the stack, or 'above'/'below' to shift one position relative to the current index. Use get_layers to see the current layer order.
photopea_resize_documentResize the active document canvas to new pixel dimensions, resampling all layer content to fit. This is a destructive operation — all layers are scaled proportionally. Use undo to revert if needed.
photopea_run_scriptExecute arbitrary Photopea/ExtendScript JavaScript in the Photopea environment. Use this for advanced operations not covered by other tools. Has full access to the Photopea DOM (app, activeDocument, layers). Use with caution — scripts can modify or delete any document data.
photopea_select_layerSet a layer as the active layer by name or index. Many tools (apply_filter, apply_adjustment, fill_selection) operate on the active layer — use this to target a specific layer first. Use get_layers to find layer names and indices.
photopea_set_layer_propertiesUpdate one or more properties on a layer. Only specified properties are changed; others remain at their current values. Use get_layers to inspect current property values before modifying.
photopea_transform_layerScale, rotate, or flip a layer in-place. Modifies the layer's pixel data destructively. Use get_layers to check current layer bounds before transforming, and undo to revert if needed.
photopea_undoUndo one or more recent actions in the active document. Each step reverses one operation from the history. Use after destructive operations (apply_filter, apply_adjustment, fill_selection) to revert changes.
photopea_ungroup_layersDissolve a layer group, moving all child layers to the document root. The group folder is removed but its contents are preserved. Use get_layers to find group names.
