Book Metadata

Book Metadata MCP is an open-source Model Context Protocol (MCP) server that enables AI assistants and clients to search and retrieve detailed book metadata—including title, authors, year, description, ISBNs, cover art, and subjects—from Google Books and Open Library. It features intelligent multi-source search, high-res cover selection, batch queries (up to 20 books), and robust error/circuit breaker handling for API limits. This server is designed for developers, AI agents, and research tools that need rich, structured bibliographic data with easy integration and no API keys required for basic use.
