Vocab Voyage

What Vocab Voyage MCP server does

Vocab Voyage MCP server exposes the Vocab Voyage learning service to MCP-compatible hosts. Its content covers vocabulary preparation for ISEE, SSAT, SAT, PSAT, GRE, GMAT, and LSAT study. The service has 20 MCP tools and 17 interactive widgets, including learning views for quizzes, flashcards, study plans, progress, and session debriefs.

The Vocab Voyage MCP server supports both standalone study actions and guided sessions. An agent can retrieve a Word of the Day, inspect the available courses, request course vocabulary, explain a word in a sentence, or generate learning activities. It can also select a student, parent, tutor, or explorer persona and ask for a recommended next action.

How it works

The server is hosted at a Vocab Voyage Supabase Functions URL, so users do not need to run a local server. MCP clients connect to the remote endpoint directly, or through mcp-remote in the Claude Desktop configuration shown by the project. The repository also includes examples for calling quiz, flashcard, and progress functionality with curl, Node.js, and Python.

Interactive activities are exposed through widgets associated with tools. Flashcards can send card-level results to the recording tool, while games report answers and can award experience for a completed round. The available games include word matching, spelling, speed rounds, synonym challenges, scrambles, fill-in-the-blank exercises, context clues, word guessing, picture matching, crosswords, and word searches.

Setup and configuration

Vocab Voyage MCP server requires no installation when used through its hosted endpoint. Add the server URL as a remote MCP server in a supported client. For Claude Desktop, the documented approach runs npx mcp-remote with the hosted URL as its argument. Cursor and Cline can add the same address as a custom remote MCP server.

Personal tokens are optional. A Bearer token generated through the Vocab Voyage developer authentication page can be supplied when using authenticated features. The repository identifies personal progress as auth-only, including the progress dashboard, word-result recording, session completion, game XP, known-word marking, difficult-word marking, and adaptive-level changes.

Tools and capabilities

Core capabilities include:

• Looking up definitions, parts of speech, examples, synonyms, and antonyms.
• Generating multiple-choice quizzes with one to ten questions for a test family.
• Retrieving flashcard decks, study-plan previews, course samples, and the 13-course catalog.
• Starting one of 11 vocabulary mini-games.
• Recording card answers, completed sessions, bonus game XP, known words, difficult words, and adaptive difficulty settings when authenticated.
• Returning Sparkle coaching, starter prompts, and next-action recommendations.

The server also publishes widgets for Word of the Day, flashcards, quizzes, study plans, progress, each listed game, and session debriefs. Hosts that do not surface prompts/list can use the starter-prompt listing tool to discover six available MCP prompts.

Limitations and notes

Personalized features require a token; the public tools and hosted connection do not require local installation. The project describes the endpoint and authentication flow, but client support for interactive widgets may vary by host. The repository is licensed under MIT. The server is intended for vocabulary learning and test preparation, so it is a better fit for those workflows than for unrelated educational subjects or general database tasks.
