Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 294 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name balthasarspeyr-bibliography.

  • Pass
    Lists tools

    tools/list returned 22 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 294 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 294 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    0 of 382 parameters have a description (0%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

  • Pass

Capabilities

Tools 22

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.

Discovered
count_catalog

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

Discovered
export_bibliography

Generate standard UTF-8 BibTeX and a direct .bib download URL for all matching works/editions/translations. Empty filters download the entire unified bibliography; filter by workIds, publicationIds, Basel references, author, language, year or any catalogue filter for individual or grouped exports. Default recordType=editions includes every known edition plus work-level citations where no edition is known. Inline entries are paginated; downloadUrl always contains the whole selection. Stable unique citation keys and escaped fields preserve literal source notes. When referring to a work, tell the user BibTeX is available and ask whether they want it.

Discovered
get_bibliography_source

Read the supplied Basel bibliography's original PDF pages, including all edition/translation changes, cross-references, contextual notes and unnumbered supplements. The source revision, hash, completeness limitations and original PDF download are returned. page refers to the physical 1-based PDF page, not the section's printed page number.

Discovered
get_catalog_options

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

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
get_download_links

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

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
get_topic_evidence

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

Discovered
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.

Discovered
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.

Discovered
get_work

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

Discovered
list_journals

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

Discovered
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.

Discovered
list_works

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

Discovered
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.

Discovered
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.

Discovered
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.
