  - before: The works beside the Urantia Papers: the Bible (World English Bible) and the texts of the world's religions that Paper 131 summarizes, each in the US public domain. `id` is what the other works.* tools take ("bible" or a slug such as "dhammapada"); `unitLabel` is the word for one unit of each work.
  - after: The works beside the Urantia Papers: the Bible (World English Bible) and 21 texts of the world's religions and traditions, each in the US public domain. `id` is what the other works.* tools take ("bible" or a slug such as "dhammapada"); `unitLabel` is the word for one unit of each work.
- 2026-10-18 `cite.get` added
  - A formatted citation of one paragraph of the Urantia Papers in APA, MLA, Chicago, or BibTeX. The ref is "196:2.1", "1:196.2.1", or "196.2.1".
- 2026-10-18 `quotes.verify` added
  - Checks whether a quoted passage is in the Urantia Papers. Returns `verdict` (exact, close, not_found), the reference and exact text of the best match, each word that differs, and other places the quote appears. Case and punctuation are ignored. A quote must be at least 4 words and fall within one paragraph. Give `ref` (such as "2:5.1") to also check the reference the quote claims.
- 2026-10-18 `works.urantia_parallels` added
  - The 10 Urantia paragraphs closest in meaning to one unit of a work (the chunk that holds it). Semantic parallels, not curated ones: they do not claim that two teachings are the same. The reference must name one unit.
- 2026-10-18 `works.read` added
  - The units of a reference in one work, in order, at most 200, each with its link: one verse or passage, a short range of up to 50, or a chapter. The prefix is optional ("BG 2.47" and "2.47" are the same); for the Bible, name the book ("John 3:16").
- 2026-10-18 `works.search.semantic` added
  - Natural-language search across the Bible and the other works, or one work with `work`. The list holds the 100 nearest chunks (a few verses each); each has `similarity` and `strength` (strong, related, weak), and `meta.total` is the length of that list, and `meta.related` counts the related or better. Each result has `url` and its nearest Urantia paragraphs (semantic parallels, not curated ones).

## Tools (26)

- `audio.get`: Get the audio file URL for a specific paragraph. Accepts any paragraph reference format (globalId "1:2.0.1", standardReferenceId "2:0.1", or paperSectionParagraphId "2.0.1").
- `bible.book`: Get metadata for a single Bible book including chapter and verse counts. Accepts OSIS codes ("Gen"), USFM codes ("GEN"), full names ("Genesis"), and aliases ("genesis", "1-maccabees") — case-insensitive, hyphens/underscores tolerated.
- `bible.books`: List all 81 books of the World English Bible (eng-web): 39 Old Testament + 15 deuterocanonical + 27 New Testament. Each entry includes OSIS book code, full name, abbreviation, canonical order, canon, and chapter/verse counts.
- `bible.chapter`: Get every verse in a Bible chapter, ordered by verse number. Accepts OSIS, USFM, full name, or alias for `book_code`.
- `bible.search.semantic`: Free-form natural-language search across all Bible chunks, ranked by cosine similarity. Each result includes the top-N pre-computed Urantia paragraphs related to that chunk. One query surfaces both Bible matches and the relevant Urantia content. Optional filters: `canon` (`ot`, `deuterocanon`, `nt`) and `book_code`. Set `urantia_parallel_limit` to 0 to leave out the Urantia paragraphs.
- `bible.verse`: Get a single verse from the World English Bible (eng-web). Accepts OSIS, USFM, full name, or alias for `book_code`.
- `bible.verse.urantia_parallels`: Returns the top 10 Urantia paragraphs whose embeddings are nearest to the Bible chunk that contains this verse. Pre-computed at seed time with text-embedding-3-large (3072-d) cosine similarity. Each result carries a similarity score (0..1) and rank (1..10).

These are semantic neighbors, not a curated list of parallels.
- `cite.get`: A formatted citation of one paragraph of the Urantia Papers in APA, MLA, Chicago, or BibTeX. The ref is "196:2.1", "1:196.2.1", or "196.2.1".
- `entities.get`: Get detailed information about a specific entity by its slug ID. Returns name, type, aliases, description, related entities, and citation count.
- `entities.list`: Browse the entity catalog: beings, places, orders, races, religions, and concepts mentioned in the Urantia Papers. Supports filtering by type and searching by name.
- `entities.paragraphs`: Get all paragraphs that mention a specific entity, ordered by position in the text. Useful for studying everything said about a particular being, place, or concept.
- `papers.get`: Get a single paper with all its paragraphs. Paper IDs range from 0 (Foreword) to 196. Each paragraph has its reference, section, and plain text, so a whole paper fits in one call. `paper.audio` is one audio file of the whole paper (null when there is none). Optionally include entity mentions.
- `papers.list`: List all 197 papers of the Urantia Papers with their metadata (id, title, partId, labels), as a flat list.
- `papers.sections`: Get all sections within a paper, ordered by section number. Useful for understanding paper structure before reading specific sections.
- `paragraphs.context`: Get a paragraph with surrounding context (N paragraphs before and after within the same paper). Useful for understanding passages in context.
- `paragraphs.get`: Look up a specific paragraph by reference. Supports three formats: globalId ("1:2.0.1"), standardReferenceId ("2:0.1"), or paperSectionParagraphId ("2.0.1"). The format is auto-detected.
- `paragraphs.random`: Get a random paragraph from the Urantia Papers. Great for daily quotes, exploration, or discovering new passages.
- `quotes.verify`: Checks whether a quoted passage is in the Urantia Papers. Returns `verdict` (exact, close, not_found), the reference and exact text of the best match, each word that differs, and other places the quote appears. Case and punctuation are ignored. A quote must be at least 4 words and fall within one paragraph. Give `ref` (such as "2:5.1") to also check the reference the quote claims.
- `search.fulltext`: Keyword search across all paragraphs of the Urantia Papers. Mode "auto" (default): a reference such as "68:6.3", "103:2", "Paper 68", or a bare number such as "68" (0 to 196) gives those paragraphs; otherwise the exact phrase first, then every word, then (when few) typo fixes and most of the words. Each result has `match` (reference, exact, all, near, most); `meta.didYouMean` gives the fixed query and `meta.see` names another work the query names. Other modes: "and" (all words), "or" (any word), "phrase" (exact phrase).
- `search.semantic`: Search the Urantia Papers using semantic similarity (vector embeddings). Returns conceptually related results even without exact keyword matches. A reference such as "99:1.1" gives those paragraphs; a pasted paragraph gives itself first. Each result has `strength` (strong, related, weak) and `match` (reference, exact, similar). The list holds the 100 nearest; `meta.total` is the length of that list, and `meta.related` counts the related or better.
- `toc.get`: Get the full table of contents of the Urantia Papers. Returns the Foreword and the 4 parts, with all 197 papers and their titles.
- `works.list`: The works beside the Urantia Papers: the Bible (World English Bible) and 21 texts of the world's religions and traditions, each in the US public domain. `id` is what the other works.* tools take ("bible" or a slug such as "dhammapada"); `unitLabel` is the word for one unit of each work.
- `works.read`: The units of a reference in one work, in order, at most 200, each with its link: one verse or passage, a short range of up to 50, or a chapter. The prefix is optional ("BG 2.47" and "2.47" are the same); for the Bible, name the book ("John 3:16").
- `works.search`: Keyword search across the Bible and the other works, or one work with `work`. A reference such as "John 3:16", "Jn 3:16-18", "Dhp 183", or "BG 2.47" gives those units first. Otherwise the exact phrase first, then every word, then (when few) a typo fix in `meta.didYouMean`. Each result has `match`, `url`, and its nearest Urantia paragraphs (semantic parallels, not curated ones).
- `works.search.semantic`: Natural-language search across the Bible and the other works, or one work with `work`. The list holds the 100 nearest chunks (a few verses each); each has `similarity` and `strength` (strong, related, weak), and `meta.total` is the length of that list, and `meta.related` counts the related or better. Each result has `url` and its nearest Urantia paragraphs (semantic parallels, not curated ones).
- `works.urantia_parallels`: The 10 Urantia paragraphs closest in meaning to one unit of a work (the chunk that holds it). Semantic parallels, not curated ones: they do not claim that two teachings are the same. The reference must name one unit.
