Brings Open Library's 20M+ catalog to Claude through nine focused tools. Search books with filters for title, author, subject, publisher, ISBN, and language. Pull work metadata, list editions across different publishers and formats, or look up a specific printing by ISBN. Search authors by name, fetch bios with external IDs (Wikidata, VIAF, ISNI), and list their works. Browse subjects and resolve cover image URLs you can drop straight into markdown. Also exposes two resources for injecting work and author detail as context. Runs over stdio or as a hosted HTTP endpoint. Good for bibliographic queries, reading list assembly, or any workflow that needs structured book data without scraping.
