Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.digitalgemology%2Fgemology-glossary/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

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.

Define a term
The definition of one gemology term (for example 'crown angle', 'feather', 'fluorescence', 'scintillation', 'birefringence', 'cut grade'): a short definition, more detail, where it appears on a grading report, how Digital Gemology measures it, related terms, and its page.
termrequiredSearch the glossary
Find glossary terms by a word or a question (for example 'what do the girdle words mean', 'inclusions near the surface', 'why does a diamond sparkle'). Returns each match with its definition and page.
limitqueryrequiredtopicList the glossary
Every term in the glossary, or in one topic, with a one-line definition and its page. The topics: Grading report, Four Cs, Anatomy and proportions, Clarity characteristics, Color and fluorescence, Light performance, How we measure, Optics, Gem testing, Gemstone properties, Colored gemstones, Treatments and origin, Diamond and simulants, Cuts and shapes, Cutting and files.
topic90% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
