How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 848 tokens (~169/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_answer Check an answer and explain every option ~105
Grades the user's choice and returns an explanation for EVERY option, including the ones they did not pick. On this exam two options are frequently defensible and only one is credited, so the reasons the wrong options lose are the part worth teaching.
| Name | Type | Req | Description |
|---|---|---|---|
| exam | string | yes | Exam slug. |
| question_id | string | yes | The id from get_practice_question. |
| selected | array | yes | Option letters the user chose, e.g. ["B"] or ["B","D"]. |
No output schema declared.
No examples provided.
get_practice_question Get a practice question ~186
Returns one original practice question with its options and no answer key. Present it to the user and let them choose before calling check_answer. Pass every id already served in exclude_ids — this server is stateless and remembers nothing.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Optional domain id (e.g. "d3") to drill one area. Domain ids come from list_exams. |
| exam | string | yes | Exam slug from list_exams. |
| exclude_ids | array | – | Question ids already served in this session, so they are not repeated. |
| focus | string | – | Optional ordering by how everyone else answers these questions: "hardest" serves the highest crowd miss rates first, "traps" serves the questions most people get wrong the SAME way — a shared misconc… |
No output schema declared.
No examples provided.
list_exams List Claude certification exams ~42
The Claude certifications covered here, with exam codes, item counts, fees and the full domain list with published weights. Call this first to get valid exam slugs.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
my_progress See what this person has answered so far ~132
Their recorded history for one exam, broken down by blueprint domain with the weakest first, plus how their misses compare with everyone else's on the same free-form questions. Call this at the start of a study session to decide what to drill, and after a run of questions to show what moved. It names the domain to pass to get_practice_question, and when their misses follow the crowd's favorite wrong answers it says to drill those with focus: "traps". Only a signed-in account has history; anonymous callers are told so rather than shown zeros.
| Name | Type | Req | Description |
|---|---|---|---|
| exam | string | yes | Exam slug from list_exams. |
No output schema declared.
No examples provided.
open_study Open a study session ~144
Open or resume the study page for an exam, optionally focused on a domain or a sub-objective. Use this when someone asks to study rather than to be quizzed in chat: the page gives them a visible question they answer themselves, and once it is open a richer set of tools appears for reading and steering that screen. Returns the URL; a browser agent should navigate there.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Optional blueprint domain, e.g. "d3". |
| exam | string | yes | Exam slug from list_exams. |
| sub_objective | string | – | Optional concept, e.g. "d1.5". Ids are per-exam. |
No output schema declared.
No examples provided.
How do I install the AI Certificates MCP server?
AI Certificates is a hosted endpoint at https://aicertificates.study/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the AI Certificates MCP server?
AI Certificates is an MCP server listed in the public MCP registry as study.aicertificates/practice-exams. Practice questions for the four Claude certifications. The assistant never sees the key. This page covers its hosted endpoint (https://aicertificates.study/api/mcp).
Is the AI Certificates MCP server safe to use?
AI Certificates scores 86 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the AI Certificates MCP server expose?
AI Certificates exposes 5 tools: list_exams, get_practice_question, my_progress, open_study, check_answer. Their descriptions and schemas cost roughly 609 tokens of context every time the server is loaded.
Does the AI Certificates MCP server require authentication?
No. We connected to AI Certificates without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the AI Certificates MCP server still maintained?
AI Certificates is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
