Available tools 20

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

publication

get_publication_text

Read the downloadable EPUB/PDF text in ordered sections. Continue using nextOffset until null. Includes source URL, format and locators. Does not assume publication.text is complete. A collective source is the publication text, not necessarily one contained work.

search_publication_text

Find literal phrases, ignoring case and accents, in a public publication's extracted EPUB/PDF text. Returns bounded exact context with locators and nextOffset; no embeddings or generated summaries. A collective publication may contain several authors.

publications

get_publications

Get detailed publication records by filters.publicationIds or any combination of listing filters, including workTypes and publicationTypes. Paginated; full texts use get_publication_text.

list_publications

List publication summaries. workTypes filters contained works; publicationTypes filters derived publication classification. Filters on author/type/original year match the same contained work.

works

list_works

List public works with combinable filters, exact counts and optional facets. Includes works without digital publications. Default year is original publication year.

search_works

Search public catalog metadata and complete or selected passages with multilingual embeddings. Queries may be in any language. Evidence is grouped by bibliographic work and identifies one selected analysis language, original/translation status, source and coverage. Optional lexicalQueries provide BM25 terms in the selected analysis language. Catalog descriptions are not author quotations; partial book selection cannot establish thematic absence. Listing tools provide exhaustive bibliographies.

aggregate

aggregate_catalog

Group distinct works by up to two dimensions. Results are paginated. Edition dimensions refer to matching editions; counts must not be summed across overlapping groups.

catalog

get_catalog_options

Get recognized and enabled types, authors, language codes and public subject labels. Corpus expansion is configuration controlled.

common

get_common_life_and_mission

Return exact Spanish passages about the encounter, common work and shared mission of Hans Urs von Balthasar and Adrienne von Speyr. The service does not summarize or infer.

community

get_community_of_saint_john

Return exact Spanish passages about the identity, consecrated life, patrons, prayer and mission of the Community of Saint John, with existing related-text links. The service does not summarize or infer.

corpus

get_corpus_coverage

Get coverage and exclusions by author and original language under bibliography filters. Use before comparisons; unavailable text is not evidence of absence.

count

count_catalog

Count distinct public works, editions and journals using combined filters, including exact baselReferences or baselReferencePrefix. No bibliography or text is returned.

download

get_download_links

Get existing download links, optionally checking availability. Resolves verified source corrections. Does not generate files.

journals

list_journals

List identified journals with aliases, distinct article counts and documented original years. Unknown references are reported by count_catalog.

life

search_life_mission_and_community

Search exact Spanish passages about Balthasar, Speyr, their common mission and the Community of Saint John. Matching is lexical and accent-insensitive; results are source evidence, not generated answers.

person

get_person_life_and_mission

Return exact Spanish biographical and mission passages for Hans Urs von Balthasar or Adrienne von Speyr. The mission topic also includes explicitly identified common-mission evidence. The service does not summarize or infer.

topic

get_topic_evidence

Read bounded evidence for precomputed editorial, lexical or optional semantic topic assignments. Supports bibliography filters including baselReferences. Continue using nextOffset.

topics

get_topics_by_period

Compare precomputed thematic indicators by period. Editorial and lexical assignments are default; filters.includeSemantic explicitly includes embedding associations. firstYears requires exactly one author and starts at their earliest catalogued work. Percentages use evaluable works, not semantic top-k results.

vocation

get_vocation_discernment_contact

Use when someone is interested in the Community of Saint John, in consecrating themselves in it, or asks about vocation, discernment of a state of life, or the Spiritual Exercises. Returns the Community's Spanish invitation to personal accompaniment and official contact details.

work

get_work

Get the complete bibliographic work record and all its public publications. Author/type scope applies to IDs too.

What is Balthasar & Speyr Catalogue mostly used for?

Its tools cluster around publication, works and publications. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Balthasar & Speyr Catalogue working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 222 ms. The bar chart above shows every period we have measured.

How do I connect Balthasar & Speyr Catalogue?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Balthasar & Speyr Catalogue need an API key?

No. Balthasar & Speyr Catalogue completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 20 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Balthasar & Speyr Catalogue?

It answers our handshake in 222 ms on average, which is faster than 66% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
