Great Library Project

Lists the books in the Great Library Project, a free library of classic and ancient texts (Homer, Plato, the Gospels, Gnostic texts, Ugaritic myths, Dante and more) presented as interlinears: the original-language text with every word glossed in English beneath it, plus a flowing English translation. Returns each book's title, author, original language, how complete it is, why it matters, and links to its landing page and its word-by-word reader. Use this first to find the right book name for get_passage or search.

  }
}

Returns ONE passage of a book as an interlinear: the original text, a word-by-word table (each word, its transliteration, its everyday meaning, its literal sense where that differs, and its dictionary form), the flowing English, the editors' note, a citation string, and links to read it in the reader. Optionally adds the immediately following or preceding passage (never more than two passages per call; whole chapters or books are not available, by design). Refs look like "1.1" (Odyssey book 1 line 1), "17a" (Plato, Apology, Stephanus page), "1.1" (John 1:1), "77" (Gospel of Thomas, saying 77). When quoting, include the citation and the reader link.

}

Looks up an original-language word (mostly Ancient and Koine Greek; any accents are fine, a dictionary form works best, an inflected form usually works too). Returns the dictionary entry the library uses (headword, transliteration, part of speech, senses, etymology, and the named source lexicon such as LSJ or Autenrieth), and up to 10 places the word occurs across the library, each with a short line of context, the gloss at that spot, a citation and a link that opens the reader at that line.

{
  "type": "object",
  "properties": {
    "word": {
      "type": "string",
      "description": "The word, e.g. \"πολύτροπος\", \"λόγος\", \"ἀρετή\"."
    },
    "book": {
      "type": "string",
      "description": "Optional: prefer this book's dictionary entry and its occurrences first."
    }
  },
  "required": [
    "word"
  ]
}

Finds passages across the library (or in one book) whose English translation or original text contains the query. Returns up to 10 matches as references with one line of English and links; call get_passage to read a match word by word. Greek can be typed with or without accents.
