Schema Quality & AI Usability67
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 841 tokens (~210/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

MCP tools · 4 exposed · ~712 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_passage ~257

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.

NameTypeReqDescription
bookstringyesBook title or slug, e.g. "Odyssey", "Apology", "John", "Gospel of Thomas". See list_books.
neighborstring–Also return the passage right after or right before this one. Default none.
refstringyesPassage reference within the book, e.g. "1.1", "17a", "77".

No output schema declared.

No examples provided.

list_books ~157

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.

NameTypeReqDescription
languagestring–Optional filter on the original language, e.g. "Greek", "Coptic", "Latin", "Hebrew", "Portuguese".

No output schema declared.

No examples provided.

lookup_word ~167

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.

NameTypeReqDescription
bookstring–Optional: prefer this book's dictionary entry and its occurrences first.
wordstringyesThe word, e.g. "πολύτροπος", "λόγος", "ἀρετή".

No output schema declared.

No examples provided.

search ~131

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.

NameTypeReqDescription
bookstring–Optional book title or slug to search within.
limitinteger–How many matches, 1 to 10. Default 5.
querystringyesWords to find, e.g. "unexamined life", "the Word", "Circe", "λόγος".

No output schema declared.

No examples provided.
