Vocab Voyage MCP server

• award_game_xpFree

  Award score-based XP from a game/activity (separate from study-time XP). Cascades to the leaderboard via DB trigger. Requires sign-in.

• explain_word_in_contextFree

  Explain what a word means inside a specific sentence — useful when a word has multiple meanings.

• file_support_ticketFree

  File a real human-followup support ticket on behalf of the signed-in user. Use this when the user reports a bug, account lockout, complaint about a tutor, or anything Sparkle/the agent cannot resolve from data. The ticket is emailed to the support team and a confirmation is sent to the user with a 1-business-day SLA. Vocab Voyage is completely free, so there is nothing to bill — never raise pricing, plans or upgrades. Categories: billing (legacy, use account instead), bug, account, complaint, feedback, other. Requires sign-in.

• generate_quizFree

  Use this when the user wants to practice, be quizzed, or test their knowledge across multiple words at once. Generates a 1–10 question multiple-choice quiz for a test family (isee, ssat, sat, psat, gre, gmat, lsat, general). Renders the interactive Vocab Voyage quiz widget on supporting hosts; per-answer taps persist mastery for signed-in users. Do not use for definition lookups — call get_definition instead. Do not use for spaced-repetition flashcards — call get_flashcards instead.

• get_child_session_detailFree

  Auth-only. Parent-only. Detailed breakdown for a single child's study/quiz session — accuracy, missed words, duration. Defaults to the most recent session for the parent's first linked child if no `child_user_id` / `session_id` is supplied. Ownership-gated: returns an error for unlinked children.

• get_class_session_trendsFree

  Auth-only. Tutor-only. Aggregate class-level trends across the tutor's classes (default 14 days, max 30). Pass `class_id` to scope to one class; omit it to get a worst-first rollup across up to 25 classes plus 1–3 struggling students.

• get_class_standingFree

  Use this when a signed-in student asks how they're doing in their tutor class, who's ahead, who their rival is, or who they should challenge. Auth-only. Returns weekly XP rank inside the user's tutor class plus a winnable rival suggestion (similar weekly XP). NEVER name the class leader unless the user is rank #1 — the response uses '(top student)' as a deliberate placeholder. Renders the interactive class-standing widget on supporting hosts; falls back to markdown elsewhere. Anonymous callers receive a sign-in prompt.

• get_course_word_listFree

  Get a sample of vocabulary words from a specific Vocab Voyage course. Use list_courses to discover slugs.

• get_definitionFree

  Use this when the user asks what a specific word means, requests its definition, part of speech, synonyms/antonyms, or an example sentence. Returns curated dictionary data from the Vocab Voyage corpus. Do not use for sentence-level meaning disambiguation (call explain_word_in_context) or for daily word prompts (call get_word_of_the_day).

• get_flashcardsFree

  Use this when the user asks for flashcards, wants to drill words individually, or wants a tap-to-flip review session. Returns 1–12 cards for a test family. Renders the interactive Vocab Voyage flashcards widget on supporting hosts; per-card 'I knew it / I didn't' buttons persist mastery for signed-in users. Do not use for multiple-choice testing (call generate_quiz) or for a single word lookup (call get_definition).

• get_my_progressFree

  Use this when the signed-in user asks about their own streak, XP, words mastered, recent activity, or 'how am I doing'. Auth-only personal dashboard. Renders the interactive Vocab Voyage progress widget on supporting hosts; falls back to markdown elsewhere. Anonymous callers receive a sign-in prompt. Do not use for global stats or other users' progress.

• get_pending_invitesFree

  Use this when the signed-in user asks about pending parent invites, share codes, or whether their parent invite has been accepted yet. Returns each pending invite with hours_until_expiry. RULE: if any invite has hours_until_expiry < 24 (and not expired), proactively offer to resend it via the resend-parent-invite flow. If expired, offer to send a fresh invite. Requires sign-in.

• get_recent_mistakesFree

  Use this when the signed-in user asks about words they've gotten wrong, missed words, words to review, or wants to revisit recent mistakes. Returns up to 25 words from the last N days (default 7) with miss-rate and last-seen timestamp, plus a link to the in-app Recent Mistakes page. SUMMARISE — never dump every row; tell the user the count, name 2–3 sample words, and recommend the page URL. Requires sign-in.

• get_recommended_next_actionFree

  One-line 'do this next' hint derived from the user's current lifecycle phase. Useful when the agent wants a quick recommendation without rendering a full guidance card.

• get_session_detailFree

  Use this when the signed-in user asks 'what did I miss in [that session]', 'which words tripped me up', or 'what was my accuracy on session X'. Pass a session_id (study_sessions.id or adaptive_sessions.id, usually obtained from get_recent_session_results / a picker chip). Returns title, accuracy %, wrong_words[] (max 10), and a per-card timeline (truncated to first 20 events). Cite at least one wrong word and the accuracy in your reply.

• get_session_trendsFree

  Auth-only. Personal study trends over a window (default 14 days, max 90): session count, total minutes, accuracy trend (up/down/flat), and top-missed words. Use after a user asks 'how am I trending / am I improving / which words keep tripping me up'.

• get_sparkle_guidanceFree

  Returns Vocab Voyage's lifecycle-aware guidance: the user's current phase (e.g. student.at_risk), a friendly greeting, 2–3 recommended tool calls, and an optional CTA. Renders the session-debrief widget on supporting hosts. Anonymous callers get visitor.* phase suggestions.

• get_study_plan_recommendationFree

  Auth-only. Returns a personalized N-day study plan (default 7, range 3–7) chosen from one of four focus modes (weak-topic-drill / streak-recovery / new-words / review-mastery) based on the user's recent trends. Inline only the first 3 days; full plan persists when the user clicks the Vocab Voyage start link.

• get_word_of_the_dayFree

  Use this when the user asks for today's word, a daily vocabulary nudge, or a single-word warmup. Returns today's deterministic Word of the Day (definition, part of speech, example, synonyms/antonyms), optionally scoped to a test family (isee, ssat, sat, psat, gre, gmat, lsat, general). Do not use for arbitrary lookups — call get_definition instead.

• list_coursesFree

  Lists all 13 Vocab Voyage courses with their slugs and descriptions.

• list_starter_promptsFree

  Lists Vocab Voyage's MCP starter prompts (also exposed via the standard MCP prompts/list endpoint). Useful for hosts that don't yet support prompts/list.

• mark_word_difficultFree

  Manually mark a word as still-learning for the signed-in user (resets mastery toward learning band). Requires sign-in.

• mark_word_knownFree

  Manually mark a word as mastered for the signed-in user (same as the flashcard 'I knew this' override). Requires sign-in.

• nudge_childFree

  Parent-only. Sends a 'check-in' push notification (and email fallback) to a linked child. Use when the parent says things like 'remind my kid to study', 'nudge my child', 'tell Sam to do their words today'. The server enforces a 24h cooldown per child — if rate-limited the response includes retry_after_hours. NEVER spoof a different parent — the calling user must already be linked to the child. Requires sign-in.

• play_gameFree

  Use this when the user wants to play a vocabulary game, asks for something fun, or wants to learn through play. Launches one of 11 mini-games inside the host chat. Renders the matching ui://vocab-voyage/game/{slug} widget on supporting hosts; falls back to a deep link elsewhere. Per-question answers persist via record_word_result; round completion fires record_session_complete + award_game_xp so MCP play counts toward streaks, XP, and mastery for signed-in users. Supported slugs: word_match, spelling_bee, speed_round, synonym_showdown, word_scramble, fill_in_blank, context_clues, word_guess, picture_match, crossword, word_search. Do not use for a serious test-prep quiz — call generate_quiz instead.

• record_session_completeFree

  Record a completed study session: writes study_sessions, awards study-time XP (+1/min, capped 30/day), and updates the daily streak. Use after a play_game / quiz / flashcard session ends. Requires sign-in.

• record_word_resultFree

  Persist a single word answer (correct/incorrect) to the user's mastery progress. Mirrors the web app's word-mastery scaling so MCP study counts toward leaderboards and streaks. Requires sign-in.

• resend_pending_inviteFree

  Resend a pending parent invite by id. Use after get_pending_invites surfaces an invite expiring in <24h, or when the user explicitly asks to resend. Re-emails the existing invite_token; no new code is generated. 60s per-invite cooldown. Caller must own the invite. Requires sign-in.

• set_personaFree

  Bias subsequent Sparkle guidance toward a persona (student | parent | tutor | explorer). Session-scoped: the host should pass the chosen persona back to get_sparkle_guidance.

• study_plan_previewFree

  Use this when the user asks for a study plan, a multi-day prep schedule, or how to prepare for a test by date. Returns a 7-day plan (5 words/day) for a given test family. Renders the interactive Vocab Voyage study-plan widget on supporting hosts; tapping 'Start Day N' launches a flashcard session seeded with that day's words. Do not use for a single quiz session — call generate_quiz instead. Do not use for one-off lookups — call get_definition instead.

• update_adaptive_levelwrite actionFree

  Run the adaptive-mastery promotion logic for the signed-in user (delegates to the web app's update-adaptive-mastery function). Requires sign-in.
