Claude Code: ask. ### `lesson_timer` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text 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": ""} (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. ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `get_free_skill` - The name "get_free_skill" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load a product's free gateway skill with its complete instructions. FREE. Typical input {"slug": "curriculum-architect-hs"} returns {"slug": ..., "skill": "", "instructions": ""}. 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": ""} (for example {"error": "unknown slug ''. Use list_products."}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `get_full_product` - The name "get_full_product" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load one product in full: its persona plus every paid skill. PREMIUM (license). Typical input {"slug": "curriculum-architect-hs"} returns {"slug": ..., "name": ..., "persona": "", "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": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `get_full_skill` - The name "get_full_skill" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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": ""}. 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": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `grade_curve` - The description's first verb is "summarize": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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": ""} (for example {"error": "no scores"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `list_products` - The name "list_products" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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": ""}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `readability_report` - The description's first verb is "analyze": a word for reading. Description, as the server wrote it: ```untrusted-server-text Analyze teaching text with Flesch-Kincaid readability and leveling advice. FREE. Typical input {"text": "", "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": ""} (for example {"error": "empty text"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `educator`: ```json { "permissions": { "allow": [ "mcp__educator__list_products", "mcp__educator__get_free_skill", "mcp__educator__readability_report", "mcp__educator__get_full_product", "mcp__educator__get_full_skill", "mcp__educator__grade_curve" ], "ask": [ "mcp__educator__lesson_timer" ], "deny": [] } } ```
