MCP server · free

Practise in your AI assistant

The questions and the theory articles of IYT Test are also an MCP server. Add it to Claude, ChatGPT or any other assistant that speaks the Model Context Protocol, and the assistant can quiz you, check your answers, explain the rule behind each one and run a mock exam, in a conversation.

The address

https://iyt.rycrentals.com/api/mcp

Public and read-only: no sign-in, no key, nothing to install.

Connect it

Claude (web, desktop and mobile): Settings → Connectors → Add custom connector, then paste the address.

ChatGPT: turn on developer mode in the settings for apps and connectors, then create a connector with the address. It needs a plan that allows custom connectors.

Claude Code, in a terminal:

claude mcp add --transport http iyt-test https://iyt.rycrentals.com/api/mcp

Cursor, VS Code and other apps that take a JSON list of servers:

{
  "mcpServers": {
    "iyt-test": {
      "type": "streamable-http",
      "url": "https://iyt.rycrentals.com/api/mcp"
    }
  }
}

Then ask

Quiz me on IALA buoyage for the Bareboat Skipper, five questions, one at a time.
Give me a Yachtmaster Coastal mock exam and grade it at the end.
I keep mixing up cardinal marks: explain them, then test me.
Ask me the question of the day in Russian.

The assistant asks each question with its four options and keeps the answer back until you choose. Most questions come with a drawing; where the assistant cannot show it, it gets a link to the image.

What it can do

`list_levels`	The levels, their topics, the mock-exam settings, and which topics have an article
`get_questions`	Random questions of a level, a topic or a difficulty, without the answers
`check_answer`	Right or wrong, the right option, the note that names the rule, and the theory section that explains it
`search_questions`	Questions by words: “cardinal mark”, “MAYDAY”
`start_mock_exam grade_exam`	An exam-sized set spread over every topic; then the score, pass or fail, the mistakes and what to read
`question_of_the_day`	The question the Telegram bot sends today
`list_theory get_theory search_theory`	The theory articles and their sections, as text with links to the drawings
`explain_question`	A question with its answer and the theory section behind it
`practice_section`	The questions a theory section covers: read, then practise
`get_figure`	A drawing as SVG

Every tool answers in English or Russian. What is not translated yet comes in English.

What it keeps

Nothing. The server asks for no sign-in and stores nothing about you or your assistant; your progress in the app is not connected to it. The details are in the privacy policy.

Where else to find it

It is listed in the official MCP Registry as io.github.nikolai-shilin/iyt-test. The questions and the articles are written for study, close to the syllabus; they are not IYT exam content.
