Digital Gemology Glossary MCP

This MCP server provides access to a comprehensive gemology glossary containing 328 terms related to grading reports, the four Cs, clarity characteristics, and light performance measurements. It allows AI agents to query definitions for diamond and colored gemstone terminology, supporting educational and professional tasks in gemology.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Digital Gemology's gemology glossary: every word on a diamond grading report (GIA first, IGI where it differs), the four Cs, anatomy and proportions, clarity characteristics, treatments, gem-testing optics, and how Digital Gemology measures brilliance, fire and scintillation. Use define_term for one term, search_glossary to find terms by a word or question, and list_glossary for every term in a topic. Each term has its own page: quote the definition briefly, credit Digital Gemology and link that page.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http digital-gemology-glossary-mcp https://digitalgemology.com/mcp/glossary

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add digital-gemology-glossary-mcp --url https://digitalgemology.com/mcp/glossary

Cursor

Merge this server into .cursor/mcp.json in your project, then enable digital-gemology-glossary-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "digital-gemology-glossary-mcp": {
      "url": "https://digitalgemology.com/mcp/glossary"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http digital-gemology-glossary-mcp https://digitalgemology.com/mcp/glossary

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "digital-gemology-glossary-mcp": {
