## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Supply Chain Security**: 13/100
  - Malware scan not yet available for this package.
  - Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.
  - No install/post-install scripts declared.
  - Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.
- **Provenance & Transparency**: 13/100
  - Repository check failed: the declared repository URL redirects; it must resolve directly.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Maintenance history not yet determined.
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1119 tokens (~139/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 47/100
  - Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 69% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-21 (score 40, −6)

- [security regression] Source repository: pass → fail
- [functional regression] Maintenance: pass → unverified

### 2026-09-20 (score 46, +1)

No change was recorded against any check on this day. Stability & Change Management went from 40 to 43. That category is still filling its 30-day observation window: 12 days of observed history at the previous scan, 13 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-18 (score 45, +1)

No change was recorded against any check on this day. Stability & Change Management went from 33 to 37. That category is still filling its 30-day observation window: 10 days of observed history at the previous scan, 11 at this one.

First indexed and scored.

## MCP tools (8)

### `list_subjects` (~61 tokens)

List subjects

과목(바인더) 목록 — 폴더 이름·학년도·학기·단원/차시 수·폴더의 파일 수, 그리고 학급 목록과 폴더 규칙. 무엇이든 시작은 여기서.

### `list_lessons` (~98 tokens)

List lessons

한 과목(또는 전부)의 단원·차시와 각 차시에 붙은 자료, 기다리는 빠진 파일. folder는 list_subjects가 준 과목 폴더 이름.

Input parameters:

- `folder` (string): 과목 폴더 이름(예 "국어 (2026-2)"). 생략하면 전 과목
- `subject` (string): 과목 이름 — 한 학기에만 있을 때

### `get_lesson` (~77 tokens)

Get one lesson

차시 하나 — 단원 번호와 차시 번호(또는 제목)로. 붙은 자료와 그 파일이 폴더에 있는지까지.

Input parameters:

- `folder` (string, required)
- `session` (number)
- `title` (string): 제목 일부
- `unit` (string): 단원 번호("1")

### `list_files` (~71 tokens)

List files in a subject folder

과목 폴더의 파일(하위 폴더 포함) — 크기·종류·파일명 배치 정보(학년_학기_단원_차시)·학급 표시. 앱이 아직 안 들인 파일도 보인다.

Input parameters:

- `folder` (string, required)

### `add_material` (~323 tokens)

Add a material file

과목 폴더에 자료 파일을 놓는다(pdf·pptx·html). 앱이 다음에 훑을 때 그 과목 자료가 된다. unit·first(·last)·grade를 주면 파일 이름 앞에 `학년_학기_단원_차시[_차시끝]_`를 붙여 그 차시(들)에 자동 배치되게 한다. class를 주면 이름 끝에 (학급)을 붙여 그 학급에만 간다. 있는 파일은 덮어쓰지 않는다.

Input parameters:

- `class` (string): 학급(예 "1반") — 그 학급에만
- `content` (string, required): 파일 내용
- `encoding` (string): 기본 utf8. pdf·pptx는 base64
- `filename` (string, required): 확장자 포함(pdf·pptx·html)
- `first` (number): 첫 차시
- `folder` (string, required): 과목 폴더 이름. 하위 폴더에 두려면 "국어 (2026-2)/학습지"처럼
- `grade` (number): 학년 — 파일 이름에만 쓰인다(배치 판정에는 안 쓴다). unit을 주면 필요
- `last` (number): 끝 차시(생략하면 first)
- `semester` (number): 학기 — 과목이 연간(semester 0)일 때만 필요
- `unit` (number): 단원 번호 — 주면 차시 자동 배치

### `read_file` (~76 tokens)

Read a text file

과목 폴더의 텍스트 파일(html·md·txt·json·csv, 2MB 이하)을 읽는다. pdf·pptx는 여기서 못 읽는다 — 파일 경로를 받아 다른 도구로.

Input parameters:

- `folder` (string, required)
- `path` (string, required): list_files가 준 path

### `plan_lessons` (~178 tokens)

Append a lesson plan

과목의 배정표(lessons.chalkie.json)에 단원·차시·자료 연결을 **덧붙인다**. 앱이 다음에 훑을 때 없는 단원·차시를 만들고 빈 제목을 채우고 자료를 이름으로 잇는다(폴더에 아직 없는 파일은 "빠진 파일"로 기다리다 같은 이름이 오면 자동 연결). 있는 것은 절대 지우거나 바꾸지 않는다. 자료는 파일 이름("학습지.pdf")·과목의 자료 이름·웹 주소·{name, kind}로 적는다.

Input parameters:

- `folder` (string, required)
- `lessonsWithoutUnit` (array)
- `pinned` (array): 과목 고정 자료(모든 차시에 붙는 것)
- `units` (array)

### `create_subject` (~147 tokens)

Create a subject folder

새 과목 폴더를 만든다 — 이름은 `과목 (학년도-학기)`, 안에 빈 배정표를 둔다. 앱이 다음에 훑을 때 그 학기에 바인더가 생긴다 (같은 이름을 앱에서 지운 적이 있으면 되살리지 않는다 — 그때는 앱에서 만든다). 그 다음 add_material·plan_lessons를 쓴다.

Input parameters:

- `name` (string, required)
- `semester` (number, required): 학기(1·2, 4학기제면 1~4). 연간이면 0
- `year` (number, required): 학년도(2026)

### Is the Chalkieboard iCloud MCP server safe to use?

Chalkieboard iCloud scores 40 out of 100 on VerifyMCP. It declares no install or post-install scripts. 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 Chalkieboard iCloud MCP server expose?

Chalkieboard iCloud exposes 8 tools: list_subjects, list_lessons, get_lesson, list_files, add_material, and 3 more. Their descriptions and schemas cost roughly 1,031 tokens of context every time the server is loaded.
