Claude Code: ask. ### `corpus_info` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text What's in the corpus: documents, layers, licenses, and counts. ``` ### `word_study` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Original-language word study across the whole Bible. Query by Strong's number ('G26', 'H2617', zero-padding optional — 'H953' works), lemma (pointed or unpointed: 'חֶסֶד' or 'חסד', accented or bare Greek), Hebrew/Aramaic transliteration ('miqweh' finds מִקְוֶה, macrons optional), or English gloss ('lovingkindness'). Returns occurrence counts, gloss range, book distribution, a full scholarly lexicon entry for the top-matching word (BDB and/or Strong's for Hebrew/Aramaic, Abbott-Smith for Greek, when available — richer than the gloss, truncated to ~700 chars), and sample verses. NOTE: homographs are split by letter-suffixed Strong's variants (e.g. H4723 'hope' vs H4723a 'gathering of waters' — same written form) — when a gloss range looks too narrow for a word you suspect is richer, probe the lettered variants; the output lists every variant lemma it finds under your query. Gloss-keyed queries match substrings and may conflate lemmas — prefer Strong's or lemma queries for exact counts. language optional: grc | hbo | arc. ``` ## Only reads (14) Looks things up and changes nothing. Claude Code: allow. ### `compare_versions` - The name "compare_versions" says "compare": a word for reading. - Tag untrusted-input: The description's first sentence says "show" and "web": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text Show a verse or short range in both BSB and WEB side by side. ``` ### `concepts_in_passage` - The description's first verb is "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List theological concepts and lexical keywords linked to a verse or chapter via the OT+NT concept graph (seeded from Easton's Bible Dictionary), e.g. 'Genesis 14' or 'John 3:16'. Complements entities_in_passage (people/places/ events) with abstract themes and keyword nodes. ``` ### `entities_in_passage` - The description's first verb is "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the people, places, and events linked to a verse or chapter, e.g. 'Genesis 14' or 'John 3:16'. ``` ### `find_similar` - The name "find_similar" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find passages semantically similar to a given verse or prose paragraph ref — across scripture, Apocrypha, and the classics. E.g. 'Philippians 2:7' or 'JULIAN.27.2'. Powers parallel-finding across corpus layers. ``` ### `get_citations` - The name "get_citations" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Where a Bible verse is cited by name in the patristic corpus, extracted from the translators' own footnotes (tier 1). E.g. reference='Ephesians 5:21'. Complements get_cross_references, which links scripture to scripture; this links patristic text to scripture. COVERAGE NOTE: footnote extraction has known recall gaps — an empty result is normal and does NOT mean the verse is uncited; full-text `search` within the patristic works is the thorough probe (verbatim quotations are regularly found that the footnote index missed). ``` ### `get_concept` - The name "get_concept" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Look up a theological concept or lexical keyword in the OT+NT concept graph (5,673 nodes seeded from Easton's Bible Dictionary — see DESIGN.md #5). Returns its definition (with a pointer to the full Easton entry), verse anchors, and entities that instantiate it (e.g. Abraham for Covenant). concept_type optional: theme | keyword. A Strong's number ('G225') also resolves directly to its keyword node. For typed relations to OTHER concepts (broader/narrower/ causes/part_of/symbol_of/fulfills/associated), use get_concept_relations(name). ``` ### `get_concept_relations` - The name "get_concept_relations" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Typed relations for a concept in the OT+NT concept graph: broader/narrower (taxonomy), causes, part_of, symbol_of, fulfills, contrasts — ~430 edges, hand-reviewed against cited evidence (Phase 5/6, weight>=10 only, see DESIGN.md #5). Excludes the much larger 'associated' fallback tier by default (~139,000 mechanical shared-evidence edges, unreviewed) — pass verb='associated' to include it. verb optional: restrict to one verb (broader | narrower | causes | part_of | symbol_of | fulfills | contrasts | associated). ``` ### `get_cross_references` - The name "get_cross_references" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Cross-references for a verse (OpenBible.info, ranked by community votes), with the target text included. E.g. reference='Romans 5:12'. ``` ### `get_entity` - The name "get_entity" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Look up a biblical person, place, event, or people group by name (Theographic knowledge graph). Returns details and where they appear. entity_type optional: person | place | event | people_group. ``` ### `get_interlinear` - The name "get_interlinear" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Word-by-word original language for a verse or short range: surface form, lemma, Strong's, gloss, morphology (Hebrew/Aramaic OT, Greek NT). For OT verses also shows Septuagint Greek surface text where available (Swete edition — Genesis-Malachi plus Apocrypha, Theodotion Daniel/Susanna/Bel; no lemma/Strong's/ morphology in that source, surface form only). E.g. 'John 1:1' or 'Genesis 1:1-3'. ``` ### `get_passage` - The name "get_passage" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get Bible text for a reference like 'John 3:16', 'John 3:16-18', 'Genesis 1', or 'Tobit 4:5' (Apocrypha requires version='WEB'). Versions: BSB, WEB. ``` ### `read_work` - The name "read_work" says "read": a word for reading. Description, as the server wrote it: ```untrusted-server-text Read a prose work from the corpus by paragraph range. Works: CONFESSIONS (Augustine), IMITATION (à Kempis), PILGRIM (Bunyan), PRESENCE (Brother Lawrence), JULIAN (Julian of Norwich), ORTHODOXY (Chesterton), 1CLEMENT (Clement of Rome), BARNABAS (Epistle of Barnabas). Chapters = books/chapters of the work; use search(version=) to find passages first, or corpus_info() for the full list. ``` ### `search` - The name "search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Full-text search (stemmed, ranked). Supports phrases in quotes, AND/OR/NOT, e.g. 'living water', 'faith AND works NOT law'. Optional book filter e.g. 'Psalms'. NOTE: porter stemming conflates related surface forms — 'desert' also matches 'deserted' and 'deserts' (as merits) in prose layers; quote exact phrases or add AND-terms to disambiguate. ``` ### `semantic_search` - The name "semantic_search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Meaning-based search across the whole corpus — scripture AND prose works — using embeddings, optionally fused with keyword search (hybrid, recommended). Finds passages about a theme even with no shared words, e.g. 'divine self-emptying', 'the soul's dark night'. kind optional: verse | window | paragraph. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `bible`: ```json { "permissions": { "allow": [ "mcp__bible__get_passage", "mcp__bible__search", "mcp__bible__get_cross_references", "mcp__bible__get_entity", "mcp__bible__entities_in_passage", "mcp__bible__get_concept", "mcp__bible__concepts_in_passage", "mcp__bible__get_concept_relations", "mcp__bible__compare_versions", "mcp__bible__get_interlinear", "mcp__bible__read_work", "mcp__bible__semantic_search", "mcp__bible__find_similar", "mcp__bible__get_citations" ], "ask": [ "mcp__bible__word_study", "mcp__bible__corpus_info" ], "deny": [] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__bible__compare_versions`: untrusted-input ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T15:03:15.832Z, unchanged since 2026-10-22T15:03:15.832Z.
