Open Library MCP server exposes tools that enable AI assistants to access and explore Open Library data. It provides functions to search for books by title, search for authors by name, and fetch detailed author information using an Open Library key. It also offers endpoints to obtain author photos by OLID and to retrieve book covers using identifiers such as ISBN, OCLC, LCCN, OLID, or internal IDs. The server returns structured data for both books and authors, including key metadata like titles, author names, publication years, IDs, cover URLs, and edition information. The available tools include get_book_by_title, get_authors_by_name, get_author_info, get_author_photo, get_book_cover, and get_book_by_id. Installation can be done via Smithery or manually, and the project supports Docker-based testing. A MCP Inspector can be used to connect and run tools, making it suitable for any MCP-compatible AI assistant or client to enrich conversations with Open Library information.
