Tools & capabilities
DPLA Catalog tools 6
search_itemsThe everyday search: words, title, place, a date range, holding institution, hub, item type. Each hit names its holding institution, the item's address there (`is_shown_at`), its rights statement, and whether page images can be listed. Copies of one work held in several places are flagged.search_items_advancedThe same, with every filter DPLA offers: county, state and city as DPLA geocoded them, subject, collection, publisher, format, creator, identifier, the period an item is *about*, rights, exact matching, any-of matching, sorting, and leaving out National Archives records.facet_itemsCounts before searching: which institutions hold plat books of a county, which years a run of directories covers, which hubs cover a place.get_itemUp to 20 records in full, each with `citation_parts`: the holding institution, title, date, the institution's own identifiers (call numbers, local ids, OCLC numbers, read from the harvested record too), `is_shown_at`, rights, and the DPLA id as a finder. Optionally the raw harvested record.get_item_imagesThe page images, from the IIIF manifest on the holding institution's site (Presentation API 2 and 3), a stretch of the list at a time. When a site refuses scripts, it says so and gives the address to open in a browser.api_statusWhether a key is configured (never the key), this session's calls and cache hits, and the last error. Makes no request.
MCP Open Library tools 7
search_booksSearch 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_titleSearch 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_idGet detailed information about a book using its identifier (ISBN, LCCN, OCLC, OLID).get_authors_by_nameSearch 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_infoGet detailed information for a specific author using their Open Library Author Key (e.g. OL23919A).get_author_photoGet 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_coverGet 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.
