Server-provided instructions

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

Digital Gemology's free gemology lessons: the four Cs, the anatomy of a diamond, reading a grading report, diamond versus moissanite, the bow-tie effect and more, written from the site's own measurements. Use search_lessons to find lessons, get_lesson to read one in full as Markdown, explain_term to quote what the lessons say about a term, and list_courses for the courses and their lessons. Quote briefly, credit Digital Gemology and link the lesson page; each lesson links a free quiz and the tools it uses.

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-learn-mcp https://digitalgemology.com/mcp/learn

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-learn-mcp --url https://digitalgemology.com/mcp/learn

Cursor

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