## Trust breakdown

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. 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.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1835 tokens (~262/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (7)

### `list_products` (~216 tokens)

List Products

List the 8 educator products with their included skills. FREE.

Takes no arguments. Typical input {} returns a list of 8 product objects, each {"slug":
"curriculum-architect-hs", "name": ..., "tagline": ..., "skills": ["Skill A",
...], "free_skill": "Gateway Skill Name"}. Use the returned slug values
with get_free_skill, get_full_product, or get_full_skill.

Returns metadata only - no persona text and no skill instructions. Use
when the caller wants to see what this server covers. Not for keyword
search across the whole 138-product catalog, which the catalog server's
search_catalog does, and not for instructions the caller can act on
(get_free_skill). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Output parameters:

- `result` (array)

### `get_free_skill` (~227 tokens)

Get Free Skill

Load a product's free gateway skill with its complete instructions. FREE.

Typical input {"slug": "curriculum-architect-hs"} returns {"slug": ...,
"skill": "<skill name>", "instructions": "<full skill text>"}.

Returns exactly one skill - the product's free gateway skill - chosen
automatically from the slug, with no plan required. Use when the caller
wants usable instructions immediately. Not for the product's other skills:
those are named and need get_full_skill with a skill_name, which requires
a paid plan. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'. Use list_products."}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `slug` (string, required): Product slug exactly as returned by list_products, e.g. "curriculum-architect-hs"; must be non-empty.

### `readability_report` (~295 tokens)

Readability Report

Analyze teaching text with Flesch-Kincaid readability and leveling advice. FREE.

Typical input {"text": "<passage>", "target_grade": 6} returns
{"flesch_kincaid_grade": 8.2, "reading_ease": 62.1, "sentences": N,
"words": N, "avg_words_per_sentence": N, "long_sentences_over_25w": N,
"polysyllabic_words_sample": [...], "target_grade": 6, "gap": 2.2,
"suggestions": ["..."]}.

Use on teaching text where the reading level matters. Not for scores
students earned (grade_curve) and not for general prose style, which the
creator server's analyze_writing covers. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "empty text"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `target_grade` (integer): Target grade level 1-12; when set, the report adds a gap assessment against it. 0 (default) skips it.
- `text` (string, required): The passage to analyze — at least one full sentence of plain text; must be non-empty.

### `get_full_product` (~229 tokens)

Get Full Product

Load one product in full: its persona plus every paid skill. PREMIUM (license).

Typical input {"slug": "curriculum-architect-hs"} returns {"slug": ...,
"name": ..., "persona": "<persona text>", "skills": [{"name": ...,
"instructions": ...}, ...], "free_skill": {...}}.

Returns persona plus every skill for one product. Use when the caller
wants the whole product. Not for a single skill (get_full_skill) and not
for a free look, which list_products and get_free_skill provide with no
plan. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `slug` (string, required): Product slug exactly as returned by list_products, e.g. "curriculum-architect-hs"; must be non-empty.

### `get_full_skill` (~253 tokens)

Get Full Skill

Load one paid skill's complete instructions from a product. PREMIUM (license).

Typical input {"slug": "curriculum-architect-hs", "skill_name":
"unit-planner"} returns {"slug": ..., "skill": ..., "instructions":
"<full skill text>"}.

Returns one named skill, selected by skill_name. Use when the caller wants
one specific paid skill. Not for the free gateway skill, which
get_free_skill returns with no plan, and not for every skill at once
(get_full_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `skill_name` (string, required): Exact skill name as listed in that product's "skills" array from list_products, e.g. "unit-planner"; must be non-empty.
- `slug` (string, required): Product slug exactly as returned by list_products, e.g. "curriculum-architect-hs"; must be non-empty.

### `grade_curve` (~282 tokens)

Grade Curve

Summarize how an assessment landed: stats, bands, and outliers. FREE.

Reports mean, median, std dev, quartiles, distribution by percentage
band, and flagged low outliers. Typical input {"scores": [88, 92, 75,
61, 84], "max_score": 100} returns {"n": 5, "mean": 80.0, "median":
84.0, "std_dev": ..., "q1": ..., "q3": ..., "distribution":
{"90-100%": 1, ...}, "outliers_low": [...], "reading": "..."}.

Use on a list of scores already earned. Not for the readability of the
assessment itself (readability_report). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "no scores"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `max_score` (number): Maximum possible score; must be greater than 0. Default 100.
- `scores` (array, required): Raw scores, one per student; at least 1 value, e.g. [88, 92, 75].

### `lesson_timer` (~267 tokens)

Lesson Timer

Split a class period into timed segments with sensible weighting. FREE.

The opener and closer get less time; core activities get more.
Typical input {"minutes": 50, "segments": ["Warm-up", "Direct instruction",
"Practice", "Exit ticket"]} returns {"period_minutes": 50, "plan":
[{"segment": "Warm-up", "start_min": 0, "duration_min": 8}, ...],
"note": "..."}.

Use when one fixed class period must be divided into segments. Not for
multi-day planning and not for spaced review, which the personal server's
spaced_repetition_plan builds. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "need segments and at least 5 minutes"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `minutes` (integer, required): Length of the class period in minutes; at least 5, e.g. 50.
- `segments` (array, required): Ordered segment names, e.g. ["Warm-up", "Practice", "Exit ticket"]; at least 1 entry.
