Install

How do I install the Moltline Educator Toolkit MCP server?

Moltline Educator Toolkit is a hosted endpoint at https://mcp.moltlinestudio.com/educator, 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.

MCP tools · 7 exposed · ~1,769 tokens

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 →

Tool Tokens
get_free_skill ~227

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.

NameTypeReqDescription
slugstringyesProduct slug exactly as returned by list_products, e.g. "curriculum-architect-hs"; must be non-empty.

Structured output declared, but exposes no named fields.

No examples provided.

get_full_product ~229

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.

NameTypeReqDescription
slugstringyesProduct slug exactly as returned by list_products, e.g. "curriculum-architect-hs"; must be non-empty.

Structured output declared, but exposes no named fields.

No examples provided.

get_full_skill ~253

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.

NameTypeReqDescription
skill_namestringyesExact skill name as listed in that product's "skills" array from list_products, e.g. "unit-planner"; must be non-empty.
slugstringyesProduct slug exactly as returned by list_products, e.g. "curriculum-architect-hs"; must be non-empty.

Structured output declared, but exposes no named fields.

No examples provided.

grade_curve ~282

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.

NameTypeReqDescription
max_scorenumberMaximum possible score; must be greater than 0. Default 100.
scoresarrayyesRaw scores, one per student; at least 1 value, e.g. [88, 92, 75].

Structured output declared, but exposes no named fields.

No examples provided.

lesson_timer ~267

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.

NameTypeReqDescription
minutesintegeryesLength of the class period in minutes; at least 5, e.g. 50.
segmentsarrayyesOrdered segment names, e.g. ["Warm-up", "Practice", "Exit ticket"]; at least 1 entry.

Structured output declared, but exposes no named fields.

No examples provided.

list_products ~216

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.

Input schema present but exposes no named parameters.

NameTypeReqDescription
resultarrayyes

No examples provided.

readability_report ~295

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.

NameTypeReqDescription
target_gradeintegerTarget grade level 1-12; when set, the report adds a gap assessment against it. 0 (default) skips it.
textstringyesThe passage to analyze — at least one full sentence of plain text; must be non-empty.

Structured output declared, but exposes no named fields.

No examples provided.
