Server-provided instructions

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

IYT Test: practice questions and theory for IYT sailing certification levels, the Racing Rules of Sailing and the charter check-in (6100 questions). Call list_levels first. Ask questions one at a time with options A to D and never reveal the answer before the student chooses; check_answer gives the verdict, the note and the theory section to read. Most questions have a drawing: show figure.url to the student (an SVG image) because the question usually depends on it; if you describe the drawing instead, say what is seen without naming what the question asks. The questions and articles are study material, not official IYT exam content. The app itself: https://iyt.rycrentals.com and the Telegram bot @iyt_test_bot.

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

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 iyt-test-mcp --url https://iyt.rycrentals.com/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable iyt-test-mcp in your MCP settings.
