establishedorprovisional, and cite the BnF source withretrieved_atwhere required.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-databnf Find the author Marcel Proust and list his works"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-databnf
data.bnf.fr is the open data service of the Bibliothèque nationale de France. It publishes the authority records the national library maintains: the people it catalogues, with their dates, their places, their languages and their fields of activity; the works they wrote, with the editions each work was published in; and the links to the copies digitised in Gallica. A record states whether the library considers it established or still provisional.
This server connects a chat client to that service. You can search for an author or a work by name, read a record in full, list what an author wrote, list the editions of a work, and find the digitised copies attached to either. It needs no API key and no account.

}-i keeps stdin open, which is where the protocol travels, and -t is left out
because a TTY rewrites the stream. The container needs outbound HTTPS to
data.bnf.fr, and nothing else: no volume, no port, no credential.
Bundle, without npm
Download mcp-databnf-2.2.0.mcpb from
the latest release and
open it. A client that supports MCP bundles installs it on its own, with no npm
and no configuration file to edit. The bundle carries its dependencies, so
nothing is fetched at install time.

What you can ask
« Que dit la BnF de Colette ? »
"List everything Marguerite Duras wrote."
"Which editions of that work does the library hold?"
"Are any of them digitised in Gallica?"
"When was that record last established?"
The ordinary path runs from a search to a record: a row carries an id, and
get_author or get_work reads it.
Tools
Tool | What it does |
| Finds people by name in the authority records. |
| Reads one person's record in full. |
| Finds works by title. |
| Reads one work's record in full. |
| Lists the works one person is credited with. |
| Lists the editions of one work. |
| Finds the copies digitised in Gallica for a person or a work. |
search_authors
Finds people by name in the authority records.
Argument | Type | Required | What it does |
| string, 1 to 200 characters | yes | The name to look for. |
| integer, 1 to 50, default | no | Rows to serve. |
| integer, 1 to 100, default | no | Which page of rows. |
In return: authors, each carrying id, which get_author, list_works
and find_digitised take; name as the service writes it; label, the
authority heading, usually with the dates; birth_year and death_year, null
where the record states none; role; and source_url. words_searched says
what was actually sent, has_more whether further pages exist, and
index_window_full that the index served everything it will serve for this
search.
get_author
Reads one person's record in full.
Argument | Type | Required | What it does |
| string, 1 to 200 characters | yes | The identifier a row carries. |
| boolean, default | no | Add the portraits the record points to. |
In return: the person with name, label, given_name, family_name,
other_names, birth_date and death_date as published, birth_year and
death_year as numbers, birth_place, death_place,
biographical_information, occupation, languages as ISO 639-2 codes,
countries and fields in the words of the record. A field the record leaves
empty is null.
search_works
Finds works by title.
Argument | Type | Required | What it does |
| string, 1 to 200 characters | yes | The words of the title to look for. |
| integer, 1 to 50, default | no | Rows to serve. |
| integer, 1 to 100, default | no | Which page of rows. |
In return: works, each carrying id, which get_work, list_editions and
find_digitised take; title; date, the year the record gives the work, as
published; creators; status, reading established or provisional; and
source_url. The envelope carries the same words_searched, has_more and
index_window_full a search of people returns.
get_work
Reads one work's record in full.
Argument | Type | Required | What it does |
| string, 1 to 200 characters | yes | The identifier a row carries. |
| boolean, default | no | Add the illustrations the record points to. |
In return: the work with title, label, date as published, first_year,
creators as { id, name }, languages, forms, subjects and
dewey_classes in the words of the record, expression_count, same_as for the
registers the BnF aligns it with, and catalogue_url. status reads
established or provisional, and status_statement says what the library
means by it: a provisional record is one the library has not finished checking.
list_works
Lists the works one person is credited with.
Argument | Type | Required | What it does |
| string, 1 to 200 characters | yes | The person's identifier. |
| integer, 1 to 50, default | no | Rows to serve. |
| integer, 1 to 100, default | no | Which page of rows. |

as a number where the record has one, forms, status and source_url, with
has_more to continue.
list_editions

In return: editions, each carrying its own id in the BnF catalogue, the
title this edition bears, date and year, publisher, place,
edition_statement, extent, isbn, note as the cataloguer wrote it,
catalogue_url, digitised and source_url. A field the record leaves empty is
null.
find_digitised
Finds the copies digitised in Gallica attached to a person or a work.
Argument | Type | Required | What it does |
| string, 1 to 200 characters | yes | The identifier of a person or of a work. |
|
| no | What the identifier stands for. |
| integer, 1 to 200, default | no | Links to serve. |
In return: kind, saying what the catalogue types the record as, and links,
each carrying the Gallica ark, its url, its rendering and the role the
person holds on it. links_returned_by_role counts them per role. This server
describes a digitised document and never opens one.
Established and provisional records
A record carries a status. established means the library has checked it;
provisional means it has not finished, and status_statement says so in the
library's own words. Report the status alongside anything taken from a
provisional record.
The licence, and what it asks
The BnF states one condition on these metadata:
L'utilisation de ces métadonnées est libre et gratuite sous réserve du maintien de la mention de leur source et de l'indication de leur date de récupération.
Use is free of charge, provided the source is named and the date of retrieval is
stated. Every answer carries retrieved_at in its payload and ends its text with
the source and that date. A cached answer reports the moment it was originally
read, since that is when it was retrieved. Repeat both wherever what you got is
shown.
Configuration
Every variable is optional. Set them in the env block of your client config.
Variable | Default | What it does |
| the project identity | Names your application to the BnF, with an address where a person can be reached. |
|
| Gap between two requests, from 3000 to 120000. |
|
| Deadline for one request, from 1000 to 300000. |
|
| Attempts after a transient failure, from 0 to 8. |
|
| How long an answer stays in memory, from 0 to 86400000. |
|
| Answers held in memory at once, from 1 to 5000. |
|
|
|
A value outside its range falls back to the default, and the reason is written to stderr.
Errors
Every failure carries one of six codes, a message, and where it helps a hint naming the next move.
Code | What happened | What to do |
| The service answered, and holds no such record. | Check the identifier with |
| The arguments were refused before any request went out. | Read the message, which names the argument. |
| The service asked this client to slow down. | Wait the number of seconds the hint names and call again with the same arguments. The record is still there. |
| The answer arrived in a shape this client cannot read. | Report it at the issue tracker. |
| The request did not complete. | Try again shortly. |
| The request passed its deadline. | Raise |
As a library
The layer reading the service is published on its own, with its pacing, its cache and its errors, and with no protocol attached.
import { BnfClient } from "mcp-databnf/client";
const client = new BnfClient();
const { data, cached } = await client.getAuthor("cb11907966z");
console.log(data.label, cached);getAuthor and getWork each answer { data, cached }, and throw an error
carrying one of the six codes. The three-second floor between two requests holds
here as well.
Pacing and attribution
Requests go out one at a time with at least three seconds between them, and that
floor holds however the server is configured. Each question is answered by a
SPARQL query against a public endpoint the BnF runs at its own expense, which is
why the interval is wide and the deadline long. The User-Agent always ends with
the project identity and an address where a person can be reached.
Every answer carries the source and retrieved_at, which the licence asks to be
stated wherever the metadata are shown.
This MCP server is an unofficial project, with no affiliation to the Bibliothèque nationale de France.
Privacy
This server collects nothing about you and sends nothing to its author. It runs
on your machine, contacts data.bnf.fr and nothing else, holds its answers in memory
while it runs, and writes nothing to disk.
PRIVACY.md states what a request carries and which settings change
any of it.

mcp-databnf (français)
data.bnf.fr est le service de données ouvertes de la Bibliothèque nationale de France. Il publie les notices d'autorité que la bibliothèque nationale entretient : les personnes qu'elle catalogue, avec leurs dates, leurs lieux, leurs langues et leurs domaines d'activité ; les œuvres qu'elles ont écrites, avec les éditions dans lesquelles chaque œuvre a paru ; et les liens vers les exemplaires numérisés dans Gallica. Une notice indique si la bibliothèque la tient pour établie ou encore provisoire.
Ce serveur relie un client de conversation à ce service. On peut y chercher un auteur ou une œuvre par son nom, lire une notice en entier, lister ce qu'un auteur a écrit, lister les éditions d'une œuvre, et trouver les exemplaires numérisés attachés à l'un ou l'autre. Aucune clé d'API, aucun compte.

Available Tools
7 toolsfind_digitisedGather the digitised documents attached to a recordARead-onlyIdempotent
Gather the digitised documents the Bibliothèque nationale de France catalogue attaches to one person or one work, and return them as links. Give the identifier of either; the tool asks the catalogue what kind of record it is and follows the right path. For a work it walks the editions; for a person it takes the images on the record and the digitised editions of the works they are credited with. The 'kind' returned is what the catalogue types the record as. Every result is a link for someone to open. This server reads the BnF catalogue and never requests gallica.bnf.fr, so it reports nothing about what is at the other end: not whether the document opens, not what it contains, not on what terms it may be reused. It returns links and nothing else: no publisher, no date, no ISBN. Use list_editions when which edition a copy belongs to matters. A 'depiction' illustrates a record and can be a page that merely mentions the subject. A 'reproduction' is an edition digitised. An 'ocr' link names a machine-read text of a document, which this server does not fetch.
Inputs: id (required), kind, limit. Returns: id, kind, links, notes, +3 more
get_authorRead a person's recordARead-onlyIdempotent
Read one person's record in the Bibliothèque nationale de France authority file, by the identifier search_authors returns. It carries the dates and places of birth and death, the occupation the record names, the language and country it associates with the person, the field of activity with its Dewey class, and the addresses for the same person in VIAF, IdRef, DBpedia, Wikidata and ISNI. It carries no biography. The field the BnF calls biographical information is a job title on most records and a single word on many, so quote it as what the catalogue states and do not build a life story out of it. It lists no work. list_works walks from this record to the works the catalogue names the person the creator of, and states what that link does and does not reach. 'depictions' are images data.bnf.fr attaches to the person. They are links for a person to open; this server does not read them, and an image can be a page that mentions the person rather than a portrait of them.
Inputs: author_id (required), include_depictions. Returns: notes, author, depictions, retrieved_at, +1 more
get_workRead a work's recordARead-onlyIdempotent
Read one work's record in the Bibliothèque nationale de France catalogue, by the identifier search_works returns. It carries the title, everyone the record credits, the date the BnF gives the work, its language, its form and its subject with the Dewey class. 'forms' holds the work-form vocabulary's own terms, which carry no label in this dataset, so some read as words and some do not. A record stating none has a form the catalogue does not state. 'status' says whether the record is established or provisional, and 'status_statement' repeats what the catalogue itself states. A provisional identifier can change, so cite an established one where there is a choice. 'expression_count' counts the expressions the record links, which is not a count of published editions: use list_editions for those.
Inputs: work_id (required), include_depictions. Returns: work, notes, depictions, retrieved_at, +1 more
list_editionsList the editions of a workARead-onlyIdempotent
List the published editions of one work in the Bibliothèque nationale de France catalogue, by the identifier search_works or get_work returns. Each row carries the publisher, the place, the year, the edition statement, the extent in the words of the record, the ISBN when there is one, and the record in the BnF general catalogue. An edition that has been digitised carries a link under 'digitised'. That link says a copy exists at that address; this server never opens it, so it cannot say whether the document is readable, complete, or free to reuse. Rows are ordered by the address the catalogue gives each edition, which is neither by date nor by importance.
Inputs: work_id (required), page, limit. Returns: page, notes, work_id, editions, +3 more
list_worksList the works a person is credited withARead-onlyIdempotent
List the works the Bibliothèque nationale de France catalogue names one person the creator of, by the identifier search_authors returns. This is the tool for 'what did this person write'. Each row carries the title, the date the record gives the work, the form codes the catalogue points at, whether the record is established or provisional, and the identifier get_work, list_editions and find_digitised take. It is not a bibliography. It reports one link the catalogue holds, and the catalogue credits a person on a record in other ways and holds editions whose work it has never established, so a work missing here is not a work the person did not write. The form codes are the work-form vocabulary's own terms and carry no label in this dataset, so some read as words and some do not. A work stating no code has a form the catalogue does not state, so keeping the rows carrying one code finds the works that declare it and never all the works of that form. Rows are ordered by the address the catalogue gives each work, which is neither chronological nor an order of importance. No total is reported, because the catalogue counts nothing here and a count would read as a measure of what the person wrote.
Inputs: author_id (required), page, limit. Returns: page, notes, works, has_more, +2 more
search_authorsFind a person in the BnF authority fileARead-onlyIdempotent
Find a person in the Bibliothèque nationale de France authority file by name, and get the identifier the other tools take. This matches the name the BnF records, so it takes a surname, a full name or both names in either order. It does not read biographies, so it cannot find a person from what they wrote or what they did. It reads the person records and nothing else: an organisation, a conference or a place is outside it, and an answer holding no row says nothing about those. The match is letter for letter, so a name written with other accents or under another transliteration is a different search: try the spellings a library would use before concluding the BnF holds nobody of that name. Several rows can carry one name: the BnF keeps more than one authority record for some people, and many people share a name. Read 'birth_year', 'death_year' and 'role' to tell them apart, and show the caller the choice rather than picking one. Rows come back ordered by the address of the record, which is not an order of relevance. That order is the one the pages are cut along, so paging through a search reaches every match once. One search reads a fixed window of the index. 'index_window_full' says whether that window came back full: when it did, names sit past what was read, 'has_more' being false says where the reading stopped, and another reading of the same search can bring back other rows. Narrow the name to reach further.

search_worksFind a work by its titleARead-onlyIdempotent
Find a work in the Bibliothèque nationale de France catalogue by words in its title, and get the identifier get_work and list_editions take. A row matches when its title carries every word given. The index returns no measure of how well a row matches, so the rows are ordered by the address of the record and the work a person would call the obvious answer can sit anywhere in the list or on a later page. A study of a book carries the book's title, so a search for a famous title returns the criticism alongside the work. Read 'creators' to tell them apart. This reads titles and nothing else. Searching a person's name returns the works written about them, whose creators are their critics; list_works is what walks from a person to the works the catalogue names them the creator of. 'status' says whether the BnF has established the work as a record of its own or holds it provisionally under a title it has catalogued. One search reads a fixed window of the index, and that window is read before the works are told apart from everything else the index holds, so even a short list can rest on a full one. 'index_window_full' says which: when it is true, titles sit past what was read, 'has_more' being false says where the reading stopped, and another reading of the same search can bring back other rows. Add a word to the title to reach further.
Inputs: title (required), page, limit. Returns: page, notes, title, works, +4 more

Scored across 7 tools
Each tool has a distinct resource+action target, and the descriptions go out of their way to state boundaries (e.g. search_works reads titles only, list_works walks from a person to works they created; find_digitised vs list_editions is explicitly separated). The remaining overlap is on works: search_works, get_work, list_works and list_editions all touch the same resource, so an agent must read carefully, though the descriptions do resolve it.
The set follows a clean verb_noun pattern (search_authors, get_author, search_works, get_work, list_editions, list_works) with consistently snake_case naming. The only deviation is find_digitised, which names no object noun and uses a fourth verb (find), a minor inconsistency in an otherwise predictable scheme.
Seven tools is well within the ideal range and each one earns its place: a search/get pair for each of the two entity types, plus editions, creator-works and digitised-link listings. No tool looks like filler or a redundant variant of another.
The author and work lifecycles are covered end to end (search to get to editions to digitised links), with explicit notes on what each link does not reach. Gaps remain: expressions are counted by get_work but there is no tool to list them, no edition-level lookup (e.g. by ISBN), and no subject/Dewey browse, though these are workable omissions for a catalogue-browsing server.
