AIDataNordic/alexandria-mcp

List books in the Alexandria collection, optionally filtered by author, subject or language. Returns unique books (one entry per Archive.org identifier) with metadata, plus the total number of matching books in the collection. At least one filter parameter is recommended — without filters, results are arbitrary. Args: author: Filter by author/creator name, e.g. 'Kant', 'Nietzsche', 'Plato'. Case-insensitive substring match against the creator field. subject: Filter by subject keyword, e.g. 'ethics', 'logic', 'metaphysics'. Case-insensitive substring match against the subject field. language: Filter by language code, e.g. 'eng', 'ger', 'lat', 'fre', 'gre', 'rus'. limit: Maximum number of distinct books to return (default 20, max 100). Returns: Dict with 'books' (list of matching books with metadata) and 'total_chunks_matched' (total number of matching text chunks in the collection, useful for pagination planning).

Simple connectivity test. Returns a greeting to confirm the server is running.

Case-insensitive substring match. language: Optional — filter by language code, e.g. 'eng', 'ger', 'lat', 'fre', 'ita', 'gre', 'rus' date_from: Optional — filter by Archive.org digitization year, not philosophical era. Use to exclude very early or very late scans, e.g. date_from=1850. WARNING: ancient texts (Plato, Aristotle, Stoics) were digitized ~1900–1920 and will be EXCLUDED by date_to < 1900. Use author= to filter by philosopher instead. date_to: Optional — upper bound on digitization year, e.g. date_to=1910. limit: Number of results after reranking (default 5, max 20) Returns: List of relevant text excerpts with metadata, reranked by relevance. Each result includes rerank_score, vector_score, title, creator, date, language, subject and the full text chunk.
