Tools & Capabilities Breakdown
MCP Open Library Tools (7)
search_books
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.
