A hosted vocabulary learning toolkit built for standardized test prep. You get 20 tools covering word definitions, test-specific quizzes (SAT, GRE, GMAT, LSAT, ISEE, SSAT), course word lists, study plans, and a word of the day endpoint. The REST API underneath is zero-auth with 60 requests per minute anonymous, and the MCP layer adds optional personal tokens for higher limits. Reach for this when you're building tutoring agents, study assistants, or chatbots that need curated vocab by test family. The source also exposes 11 mini-games and spaced repetition data, plus parent dashboards if you're targeting family or classroom workflows. Runs entirely on Supabase functions, so no self-hosting required.
