Kabbalah MCP Server by RoxyAPI

Calculate gematria - Hebrew gematria calculator API with every spelling shown

post_kabbalah_gematria
Read-only

Score a Hebrew word or a Latin name across ten rabbinic gematria ciphers and two substitution transformations, with the per letter breakdown and the curated equal value matches beside each number. A Latin name has no single Hebrew spelling, so every candidate spelling the transliteration map produces comes back with its own values and the rule that produced it, and the chosen one is named. Built for name meaning features, numerology apps that want the Hebrew reading, and any product that has to show a reader why the number is what it is.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
langNoResponse language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.en
textNoLatin text to write in Hebrew and then score, up to 200 characters. Non Latin scripts are folded to Latin first, so a Cyrillic or Devanagari name works. Send textHebrew instead to control the Hebrew spelling yourself.
ciphersNoWhich ciphers to return, by identifier. Omit for every computed cipher. Valid values are mispar-hechrachi, mispar-gadol, otiyot-be-milui, mispar-katan, mispar-kidmi, mispar-prati, mispar-ha-merubah-ha-klali, mispar-meshulash, mispar-musafi, kolel.
compactNoSet true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.
textHebrewNoHebrew text to score, up to 200 characters. Anything outside the Hebrew script is rejected. Vowel points, cantillation marks, maqaf and paseq are removed before scoring, so a pointed and an unpointed spelling of one word give the same number.
misparGadolNoWhich method the name mispar gadol means, because the sources use it for two. Use finals-500-900 to score the five word final letters as 500 to 900, or milui to score each letter as the value of its own spelled out name.finals-500-900
atbashOutputNoWhat AtBash and Albam return: the substituted Hebrew string, its standard value, or both. The biblical witness for AtBash is a substituted WORD rather than a number, which is why the string is available on its own.both
latinCiphersNoWhether to also score the Latin text with the three Latin alphabet ciphers. They are Renaissance Christian and modern in lineage rather than rabbinic, and the response labels each one. Ignored when textHebrew was sent.
includeMatchesNoWhether to return the curated equal value entries for the chosen spelling. Set false to skip the lookup when only the numbers are wanted.
transliterationNoHow a Latin name is written in Hebrew before it is scored. Two members. letter-map-mathers is the 1887 Hermetic letter map, with e read as its author practised it: a point inside a word and alef at the start of one. It writes no c, f, w or x, so a name carrying one of them outside a two letter group returns 400 naming the letter. letter-map-modern follows the modern Israeli transcription rules for the sound each Latin letter carries in English and French spelling, covers every Latin letter, drops the geresh and does not double vav or yod, so send textHebrew for the ktiv male form. Every form states the readings it used in rule. Phonetic Ashkenazi and Sephardi schemes are not offered because no two references agree on a rule for that direction.letter-map-mathers

  4. First observed

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With readOnlyHint=true and destructiveHint=false, the safety profile is already established. The description adds valuable behavioral context: Latin names produce every candidate Hebrew spelling with the producing rule, the chosen spelling is named, and results include per-letter breakdowns and curated matches. This goes beyond what the annotations alone convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences with no wasted words. It front-loads the core action, explains the important Latin-name edge case, and closes with use cases. This is appropriate for a complex tool because the schema handles the detailed parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the 10-parameter schema, 100% parameter coverage, output schema, and read-only annotations, the description is complete enough. It addresses the most confusing behavior—multiple Hebrew spellings for Latin names—and the schema covers the remaining details. No essential agent decision is left unexplained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description provides helpful framing for ciphers and transliteration but does not need to restate parameter details. It adds conceptual context, not new syntax or format information beyond what the schema already gives.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Score a Hebrew word or a Latin name across ten rabbinic gematria ciphers and two substitution transformations.' It also names concrete output components (per-letter breakdown, equal-value matches), making it clear what the tool does and how it differs from profile/name-oriented siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly states the intended contexts: 'name meaning features, numerology apps that want the Hebrew reading, and any product that has to show a reader why the number is what it is.' It does not explicitly list excluded cases or name sibling alternatives, but the use-case guidance is strong enough for an agent to select it appropriately.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
