Choose Photopea MCP Server if your workspace requires Art & Culture integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose MCP Open Library when:
You need dedicated capabilities in the Art & Culture domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Search Open Library across titles, authors, subjects, places, people, publishers and ISBNs. Provide at least one search criterion: q, title, author, subject, place, person, publisher, isbn; combining several narrows the search. Returns at most `limit` results (default 10) together with `num_found`, the total number of matches; page through them with `offset`. Each result carries `best_edition` — one edition of the work, with its `isbn_13`/`isbn_10` where Open Library has them, and its `edition_key`, which can be passed to `get_book_by_id` as `{ idType: "olid" }` for that edition's full record.
get_book_by_title
Search for a book by its title on Open Library. Returns at most `limit` results (default 10) together with `num_found`, the total number of matches; page through them with `offset`. Each result carries `best_edition` — one edition of the work, with its `isbn_13`/`isbn_10` where Open Library has them, and its `edition_key`, which can be passed to `get_book_by_id` as `{ idType: "olid" }` for that edition's full record.
get_book_by_id
Get detailed information about a book using its identifier (ISBN, LCCN, OCLC, OLID).
get_authors_by_name
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
MCP Open Library is categorized under Art & Culture and uses a local stdio subprocess. In contrast, Photopea MCP Server belongs to Art & Culture using local stdio subprocess. Select MCP Open Library when you need capabilities focused on art & culture and Photopea MCP Server when you require tools for art & culture.
Search for author information on Open Library. Returns at most `limit` authors (default 10) together with `num_found`, the total number of matches; page through them with `offset`. Each result's `key` can be passed to `get_author_info` for that author's full record.
get_author_info
Get detailed information for a specific author using their Open Library Author Key (e.g. OL23919A).
get_author_photo
Get the URL for an author's photo using their Open Library Author ID (OLID e.g. OL23919A). Reports when no photo exists rather than returning a URL to a blank placeholder.
get_book_cover
Get the URL for a book's cover image using a key (ISBN, OCLC, LCCN, OLID, ID) and value. Reports when no cover exists rather than returning a URL to a blank placeholder.
Photopea MCP Server Tools (34)
photopea_create_document
Create 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_open_file
Open 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_get_document_info
Get 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_resize_document
Resize 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_close_document
Close 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_add_layer
Add 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_fill_layer
Add 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_delete_layer
Permanently 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_select_layer
Set 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_properties
Update 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_move_layer
Translate 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_duplicate_layer
Create 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.
