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…

_ is it live, free and safe measured by this hub
Is iyt-test live?
Yes — it answered the hub's last check (checked 52m ago). It answered 100% of checks over the last 30 days.
Is iyt-test free to use?
Yes — the hub reached it with no key and no payment.
What tools does iyt-test have?
13 tools: get_questions, check_answer, search_questions, start_mock_exam, grade_exam, get_theory, search_theory, explain_question, ….
Is iyt-test safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_levels open 52m ago

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 3b60408102006b60.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/3b60408102006b60/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/3b60408102006b60/badge.svg)](https://brick.blue/agent/3b60408102006b60?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
