MCP Open Library

MCP Open Library is an MCP server that connects AI assistants to the Open Library catalogue API to retrieve book, edition, and author metadata. Built for researchers, developers, and bibliophiles using Model Context Protocol clients like Claude Desktop, it enables tools to query millions of library records directly within natural language conversations. The server provides tools to search works across titles, authors, subjects, publishers, and ISBN identifiers, returning structured JSON projections instead of raw API dumps. Users can inspect specific editions using standard identifiers such as ISBN, OCLC, LCCN, or Open Library IDs (OLIDs), as well as fetch author biographies, alternate names, and work counts. In addition, MCP Open Library includes dedicated tools for verifying and retrieving cover art and author photo URLs, ensuring image resources exist before serving them to the client. All tools are read-only lookups that include standard error reporting, allowing assistants to automatically refine subsequent queries when requests fail.

Alternatively, install it from the MCP Registry under io.github.8enSmith/mcp-open-library.

Which MCP clients work with MCP Open Library?

MCP Open Library works with any client compliant with the Model Context Protocol specification that supports stdio transport. This includes Claude Desktop, the MCP Inspector, and other compatible developer environments configured to execute Node.js packages.

What tools are included in MCP Open Library?

The server exposes seven read-only tools: search_books for advanced catalogue searches, get_book_by_title, get_authors_by_name, get_author_info for detailed author records, get_author_photo, get_book_cover for image URLs, and get_book_by_id for querying works via ISBN, LCCN, OCLC, or OLID.
