Vocab Voyage
SAT/ISEE/SSAT/GRE/GMAT/LSAT/PSAT vocab tools. 7 MCP tools + UI widgets. Hosted, no install.
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.
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).
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 a sample of vocabulary words from a specific Vocab Voyage course. Use list_courses to discover slugs.
Lists all 13 Vocab Voyage courses with their slugs and descriptions.
Explain what a word means inside a specific sentence — useful when a word has multiple meanings.
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.
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).
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.
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.
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.
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.
Award score-based XP from a game/activity (separate from study-time XP). Cascades to the leaderboard via DB trigger. Requires sign-in.
Manually mark a word as mastered for the signed-in user (same as the flashcard 'I knew this' override). Requires sign-in.
Manually mark a word as still-learning for the signed-in user (resets mastery toward learning band). Requires sign-in.
Run the adaptive-mastery promotion logic for the signed-in user (delegates to the web app's update-adaptive-mastery function). Requires sign-in.
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.
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.
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.
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.
