MCP server

Your exam prep, inside the assistant you already use

Connect one URL and your assistant quizzes you on the real blueprint — one question at a time, withholding the answer key until you commit, then explaining why every option wins or loses.

Which URL

/api/mcpFree · no account

The free form for each exam — 236 questions. No account needed, and without one nothing is recorded.

/api/mcp/fullFull access

Every question bank for all four certifications, and it tracks your answers by blueprint domain — so it drills you on what you get wrong, weakest domain first.

Two, not one: a client only offers sign-in after a server refuses it once, and the free endpoint never refuses anybody.

Claude Codeterminal

claude mcp add --transport http ai-certificates https://aicertificates.study/api/mcp/full

Then run /mcp and sign in. No purchase yet? Swap the URL for /api/mcp and skip the sign-in.

claude.aibrowser

01Open Customize → Connectors.

02Click +, then Add custom connector.

03Paste the URL and click Add. Advanced settings stay empty — the server describes its own sign-in.

Free plans get one custom connector. On Team and Enterprise an Owner adds it once under Organization settings → Connectors; everyone else clicks Connect.

ChatGPTbrowser

01Turn on Developer mode under Settings → Security and login.

02Add a plugin: click +, give it a name and description.

03Choose Public endpoint and paste the URL.

OpenAI says developer mode depends on your account and workspace policy, so it is not on every plan.

Codexterminal

Codex adds hosted servers in ~/.codex/config.toml:

[mcp_servers.ai-certificates]
url = "https://aicertificates.study/api/mcp/full"

Then codex mcp login ai-certificates opens the sign-in. codex mcp add takes a local command rather than a URL, so it is the config file for a hosted server like this one.

Or let the assistant do it:one copied prompt covers all four clients — paste it into whatever you use and it walks you through your own screen.

Paste into an assistant and it will walk you through your own client.

Four tools

list_examsAll four Claude certifications with codes, fees, and every domain at its published weight.
get_practice_questionOne question, options shown, no answer key. The assistant cannot leak what it was not given.
check_answerGrades after you commit and explains every option, including the ones you did not pick.
my_progressYour record by blueprint domain, weakest first — what the drilling runs on. Full endpoint only.

Why not paste questions into a chat?

A model that can see the answer key either hands it to you or folds when you argue. Over MCP it gets the question and not the key — you commit first, then it explains why the near-misses lose. On these exams two options are usually defensible and one is credited; the difference is the lesson.

What is recorded:the outcome only — which question, which domain, right or wrong. No conversation is stored, and without an account nothing is recorded at all. More on the privacy page.
