Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 10 outils

• openlibrary_get_author≈ 899 tokens

  Fetch author detail by Open Library Author ID (OL…A). Returns bio, birth/death dates, photo IDs, and linked identifiers from Wikidata, VIAF, ISNI, Goodreads, and LibraryThing. Use openlibrary_search_authors to find an author ID first.

  Paramètres, retour & exemple (1)

  Paramètres

  • author_id · string · requis
    Open Library Author ID. Format: OL…A (e.g., "OL24638A"). A leading "/authors/" prefix is stripped if provided.

• openlibrary_get_author_works≈ 885 tokens

  List works by an author. Returns titles, cover IDs, and work OLIDs for drilling into editions or details. Use openlibrary_get_author for author bio and details, or openlibrary_get_editions to explore specific printings.

  Paramètres, retour & exemple (3)

  Paramètres

  • limit · integer · optionnel
    Max works to return.
  • offset · integer · optionnel
    Zero-based offset for pagination.
  • author_id · string · requis
    Open Library Author ID (OL…A). A leading "/authors/" prefix is stripped if provided.

• openlibrary_get_cover_url≈ 962 tokens

  Resolve a cover image URL for a book or author photo. Returns a direct HTTPS URL in the requested size (S/M/L). The Covers API always returns HTTP 200 — missing covers return a 1×1 placeholder GIF, not a 404 — so the identifier format is validated locally first: "id" must be numeric, "isbn" 10 or 13 digits (an ISBN-10 may end in an X check digit), "olid" an edition OLID (OL…M) for target "book" and an author OLID (OL…A) for target "author". Identifiers with path separators or control characters, and author-by-ISBN lookups, are rejected before any request. URLs can be embedded in markdown as .

  Paramètres, retour & exemple (4)

  Paramètres

  • size · string · optionnel · S | M | L
    Image size. S = small (~45px tall), M = medium (~150px tall), L = large (~400px tall).
  • target · string · optionnel · book | author
    "book" returns a book cover from covers.openlibrary.org/b/. "author" returns an author photo from covers.openlibrary.org/a/ — use with id_type "id" (photo_id) or "olid" (author OLID).
  • id_type · string · requis · id | isbn | olid
    "id" is the numeric cover_i / cover ID from search or work results. "isbn" and "olid" look up the cover from those identifiers.
  • identifier · string · requis
    The identifier value, validated against id_type before the URL is built. For "id": a numeric cover or photo ID from work/edition/author data. For "isbn": 10 or 13 digits, hyphens optional — an ISBN-10 may end in an X check digit (e.g., 080442957X). For "olid": an edition OLID (OL…M) for target "book", an author OLID (OL…A) for target "author".

• openlibrary_get_edition≈ 1907 tokens

  Resolve one or more editions by identifier: ISBN-10, ISBN-13, OCLC, LCCN, or Open Library Edition ID (OL…M). Every identifier in a call shares one id_type — pass id_type "isbn" for both ISBN-10 and ISBN-13. Up to 50 identifiers resolve in a single upstream request, so a bibliography or shelf export costs one call rather than one per book; a large batch is a large response, so ask for what you need. Returns full edition metadata including authors, publisher, language, all identifier types, and the parent work ID, with author names inline and no secondary lookup; when the edition record itself lists no authors, they are recovered from the parent work and marked as such, and a notice names any edition whose recovery failed. Partial success is the norm — identifiers that resolve come back in editions, the rest are listed in unresolved with a reason, and the call fails only when nothing resolved.

  Paramètres, retour & exemple (2)

  Paramètres

  • id_type · string · requis · isbn | oclc | lccn | olid
    Identifier type shared by every entry in identifiers. "isbn" handles both ISBN-10 and ISBN-13. "olid" is the native Open Library edition ID (OL…M). Mixing types within one call is not supported — issue one call per type.
  • identifiers · array · requis
    Identifiers to resolve, 1–50, all of the type named by id_type. Resolved editions come back in request order.

  Exemple d'appel

  {"name": "openlibrary_get_edition", "arguments": {"id_type": "isbn", "identifiers": []}}

• openlibrary_get_editions≈ 1183 tokens

  List editions of a work — different publishers, languages, formats, and print runs. Returns ISBNs, publisher, language, page count, and edition OLIDs. Use after openlibrary_get_work or openlibrary_search_books to find a specific printing. A merged work ID resolves to the work it was merged into. To reach a work from an ISBN, call openlibrary_get_edition with id_type "isbn" — its work_id output is the parent work.

  Paramètres, retour & exemple (3)

  Paramètres

  • limit · integer · optionnel
    Max editions to return. Prefer 10–20 for exploration.
  • offset · integer · optionnel
    Zero-based offset for pagination.
  • work_id · string · requis
    Open Library Work ID. Format: OL…W (e.g., "OL45804W"), optionally prefixed "/works/". Not an ISBN — resolve an ISBN to its work with openlibrary_get_edition (id_type "isbn").

  Exemple d'appel

  {"name": "openlibrary_get_editions", "arguments": {"work_id": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}], "structuredContent": {"error": {}, "total": 1, "notice": "texte", "offset": 1, "work_id": "texte", "editions": [], "totalCount": 1}}

• openlibrary_get_subject≈ 956 tokens

  Browse works by subject. Returns matching works with edition counts and cover IDs, plus the total work count for the subject. Case and spacing are normalized before lookup, so "Science Fiction" and "science_fiction" are the same request. Subject tags are user-contributed and the vocabulary varies — when a subject returns no works, try a different word form (singular/plural), a synonym, or a broader term.

  Paramètres, retour & exemple (3)

  Paramètres

  • limit · integer · optionnel
    Max works to return. Subject pages typically show 12 at a time.
  • offset · integer · optionnel
    Zero-based offset for pagination.
  • subject · string · requis
    Subject name. Normalized before lookup — lowercased with spaces converted to underscores (e.g., "Science Fiction" → "science_fiction") — so varying case or spacing does not change the result.

  Exemple d'appel

  {"name": "openlibrary_get_subject", "arguments": {"subject": "texte"}}

  Exemple de retour

• openlibrary_get_work≈ 1006 tokens

  Fetch a work by Open Library Work ID (OL…W). Returns title, description, subjects, cover IDs, and linked author IDs for follow-up lookups. Works represent the abstract book concept independent of any specific edition. A merged work ID resolves to the work it was merged into. To reach a work from an ISBN, call openlibrary_get_edition with id_type "isbn" — its work_id output is the parent work. Note: author names are not included — use openlibrary_get_author or openlibrary_search_books for names.

• openlibrary_search_authors≈ 989 tokens

  Search Open Library authors by name. Returns Open Library Author IDs, names, birth/death dates, top works, and subject associations. Use author IDs for openlibrary_get_author (bio, remote IDs) or openlibrary_get_author_works (list of works).

  Paramètres, retour & exemple (3)

  Paramètres

  • limit · integer · optionnel
    Max results to return.
  • query · string · requis
    Author name search query. Partial names and alternate names work.
  • offset · integer · optionnel

• openlibrary_search_books≈ 2221 tokens

  Full-text book search across Open Library works. Supports field filters (title, author, subject, publisher, ISBN, language) and returns work-level records with edition counts, cover IDs, and reading availability. Use query for general search or combine specific field filters. Results are work-level — drill into editions via openlibrary_get_editions.

  Paramètres, retour & exemple (11)

  Paramètres

  • isbn · string · optionnel
    Find works that have editions with this ISBN (10 or 13 digits, hyphens ignored).
  • sort · string · optionnel · relevance | new | old | rating | editions
    Sort order. "relevance" uses Solr scoring. "new"/"old" sort by first publish year. "rating" by average community rating. "editions" by edition count.
  • limit · integer · optionnel
    Max results to return. Higher values increase response size; prefer 10–20 for exploration.
  • query · string · optionnel
    Full-text search query. Supports Solr field prefixes: title:, author:, subject:, publisher:, isbn:, language:. Omit to use the filter parameters instead.
  • title · string · optionnel
    Filter by title. Matched against work title and alternative titles.
  • author · string · optionnel
    Filter by author name. Partial names work.
  • offset · integer · optionnel
    Zero-based offset for pagination.
  • subject · string · optionnel
    Filter by subject tag (e.g., "science fiction", "history").
  • language · string · optionnel
    Restrict results to one language. Takes a 3-letter MARC code (e.g., "eng", "fre", "ger", "chi") — the same vocabulary openlibrary_get_edition and openlibrary_get_editions return. A 2-letter ISO 639-1 code (e.g., "en", "fr") is accepted and translated to its MARC equivalent; an unrecognized 2-letter code is rejected rather than silently ignored. The equivalent in-query form is language:eng.
  • publisher · string · optionnel
    Filter by publisher name. Partial names work (e.g., "Penguin").
  • include_availability · boolean · optionnel
    Include live reading availability from Internet Archive (borrow/read status). Adds ~200ms latency. Use when the user needs to know if they can read the book online.

• openlibrary_search_inside≈ 1224 tokens

  Search the full text of books scanned by the Internet Archive — the "which book contains this passage?" lookup that the metadata tools cannot answer. Quote a phrase for an exact-phrase match; bare terms match anywhere in the text. Each result is an Internet Archive item with the matching passages as snippets, plus a relevance score. The full-text index is far slower than the metadata endpoints, and a search usually takes 10–30 seconds. Use it when the passage is the question, and use openlibrary_search_books to search by title, author, or subject. Results key on Internet Archive items rather than Open Library works: chain the returned ia_identifier to archive.org, or match it against the ia_identifiers on openlibrary_search_books results to reach the catalogue record.

  Paramètres, retour & exemple (3)

  Paramètres

  • limit · integer · optionnel
    Max matching items to return. Each carries its own snippets, so higher values grow the response quickly — prefer 10–20.
  • query · string · requis
    Text to find inside scanned books. Wrap in double quotes for an exact-phrase match (e.g., "the spice must flow"); unquoted terms match independently and return far broader results.
  • offset · integer · optionnel
    Zero-based offset for pagination.
