openlibrary-mcp
Query the Open Library (openlibrary.org, keyless): full-text book search, work details, and author details with covers and publish years.
Served over the Model Context Protocol so any MCP client (Claude, Cursor, ChatGPT connectors, custom agents) can use it. Keyless: no third-party account or API key needed.

Tools
search_books
Search Open Library by title, author or free text. Returns authors, first publish year and cover links.
search_by_author
Find books by an author name across the whole Open Library catalog.
search_by_subject
Browse a subject or genre, e.g. 'science_fiction', 'cooking', 'biography'.
get_work
Work details by ID (OL123W): description, subjects, first publish date and cover.
get_edition
Edition details by ID (OL123M): publisher, page count, ISBNs and cover.
get_author
Author details by ID (OL123A): birth/death dates, alternate names, bio and links.
author_works
List the works credited to an author ID, with publication years.
edition_by_isbn
Resolve an ISBN straight to its edition record - title, publisher, pages, language and cover - after checking the ISBN's own check digit, so a typo is caught before the request.
work_editions
Every printing of a work that Open Library holds: edition count, publication-year range, publishers, languages and the edition keys to drill into.
subject_overview
A subject as an entity rather than a search: how many works it holds and the works Open Library ranks first, with authors and first publication years.
