Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Descripción del creador (original en inglés)
Identify gemstones by refractive index, birefringence, SG, pleochroism and spectrum. Compare 7 gems
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

gem_propertiesEverything Digital Gemology measures about one gemstone: refractive index (both rays for doubly refractive stones), birefringence, dispersion, specific gravity, hardness, crystal system, critical angle, what a refractometer, polariscope and dichroscope show, its pleochroic colors
identify_gemMatch a stone's test readings against the seven gemstones Digital Gemology covers and rank them, saying which reading fits and which does not. Give any of: refractive index, birefringence, specific gravity, optic character, pleochroism, a spectrum line, or that the refractometer
compare_gemstonesTwo gemstones side by side, and the tests that tell them apart: refractive index, birefringence (doubling of back facets, polariscope), specific gravity, dispersion (fire), hardness, pleochroism and spectrum, each with the free tool that shows it. For questions like 'how do I tel
absorption_spectrumWhat a hand spectroscope shows for one gemstone: each absorption line and band with its position in nanometres, its cause (for example Cr3+ in ruby) and what it looks like, from Digital Gemology's Spectroscope.

Superó 3 de 3 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.
El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.

Four remote Model Context Protocol servers from Digital Gemology:
| Server | Endpoint | Registry name | What it does |
|---|---|---|---|
| Cut library | https://digitalgemology.com/mcp | com.digitalgemology/cut-library | Search 40 gem cuts and 5 Platonic solids; ray-traced brilliance, fire and scintillation in seven gemstones; compare cuts; recommend a cut; 3D models and GemCad faceting diagrams |
| Gem identification | https://digitalgemology.com/mcp/gems | com.digitalgemology/gem-identification | Gemstone properties; match refractive index, birefringence, specific gravity, pleochroism and spectrum lines to seven gemstones; tell two gems apart |
| Gemology lessons | https://digitalgemology.com/mcp/learn | com.digitalgemology/gemology-lessons | Search, read and quote 53 gemology lessons: the four Cs, diamond anatomy, grading reports, diamond vs moissanite, historic cuts, bow-ties |
| Gemology glossary | https://digitalgemology.com/mcp/glossary | com.digitalgemology/gemology-glossary | Define 328 gemology terms: every word on a diamond grading report, the four Cs, clarity characteristics, treatments, gem testing, colored gemstones, and how brilliance, fire and scintillation are measured |
This repository holds the servers' public description, their registry listings and the open data they serve. The servers run on digitalgemology.com.
/mcp)| Tool | What it does |
|---|---|
search_cuts | Search the cut library by name, style, shape or use ("square step cut", "round brilliant for moissanite", "historic cushion"). Returns each cut's page, facets, size, price and checkout links; give a gemstone to sort by brilliance, fire and scintillation in that stone. |
get_cut | Everything about one cut: measured specifications (facets, angles, depth, size, index gear), brilliance, fire and scintillation in all seven gemstones, prices and checkout links. |
best_cuts_for_gemstone | The top ten brilliants and top ten jewelry cuts in one gemstone, with the stone's optical constants. |
cut_in_gemstone | How one cut performs in one gemstone: eight measured scores against the T73 round brilliant, with pros and cons. |
list_gemstones | The seven gemstones (diamond, moissanite, cubic zirconia, ruby, sapphire, emerald, amethyst) with refractive index, critical angle, dispersion, hardness and specific gravity. |
get_cut_scores | The Cut Performance Index: overall, brilliance, fire, scintillation, tilt, symmetry, spread, shape-norm and leakage, in all seven gemstones. |
compare_cuts | Two cuts side by side in one gemstone: place in the index, every figure, which cut is ahead on each, and links to buy. |
recommend_cut | The best cuts for a gemstone, ranked by overall, brilliance, fire, scintillation, spread, tilt or leakage; filter by category or shape. |
/mcp/gems)The values that Digital Gemology's free Refractometer, Polariscope, Dichroscope and Spectroscope use, for diamond, moissanite, cubic zirconia, ruby, sapphire, emerald and amethyst. A match is a lead, not an identification: a laboratory report is the proof.
| Tool | What it does |
|---|---|
gem_properties | One gemstone: refractive index, birefringence, dispersion, specific gravity, hardness, crystal system, and what each instrument shows. |
identify_gem | Give any readings (refractive index, birefringence, specific gravity, singly or doubly refractive, pleochroism, a spectrum line, over the refractometer limit). Returns which of the seven stones fit each reading. |
compare_gemstones | Which tests tell two gemstones apart (for example diamond and moissanite), and which do not. |
absorption_spectrum | The lines and bands a gemstone shows in a spectroscope, with their cause. |
/mcp/learn)| Tool | What it does |
|---|---|
search_lessons | Find lessons on a topic or question ("what is fire in a diamond"). |
get_lesson | The full text of one lesson as Markdown, by title or URL. |
explain_term | Short passages from the lessons that explain a term ("critical angle", "pavilion angle"), each with its link. |
list_courses | Every course and its lessons. |
/mcp/glossary)328 terms, each with its own page under digitalgemology.com/learn/glossary. Grading report terms follow GIA, with IGI where it differs.
| Tool | What it does |
|---|---|
define_term | One term ("crown angle", "feather", "fluorescence", "scintillation"): a short definition, more detail, where it appears on a grading report, how Digital Gemology measures it, related terms, and its page. |
search_glossary | Find terms by a word or a question ("what do the girdle words mean", "why does a diamond sparkle"). |
list_glossary | Every term, or every term in one of 15 topics, with a one-line definition and its page. |

https://digitalgemology.com/api/cuts, /api/cuts/{slug}, /api/gemstones, /api/cut-index (OpenAPI)https://digitalgemology.com/a2a (agent card)data/ holds the Digital Gemology Cut Performance Index: ray-traced light-performance scores for 40 gem cuts and 5 Platonic solids in seven gemstones, diamond, moissanite, cubic zirconia, ruby, sapphire, emerald and amethyst (315 rows; 37 cuts are scored, and the rest are listed with the reason). Ruby and sapphire are both corundum, so they share one set of figures; color and absorption are not part of the trace. The method and every column are explained on the index page.
