Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 13 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability80
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1381 tokens (~106/item across 13 items; 13 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.nirajagarwal/bible-mcp server?
io.github.nirajagarwal/bible-mcp is a hosted endpoint at https://bible-mcp-server.fly.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

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).

E.g. 'John 1:1' or 'Genesis 1:1-3'.

search ~133
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.

word_study ~319
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.
