Quiz MCP

MCP server for interactive quizzes

Quiz MCP

A Model Context Protocol (MCP) server for running interactive quizzes. This tool bridges the gap between AI generation and user interaction by allowing agents to generate quizzes and immediately present them to users in a polished web interface.

Features

  • Interactive Web UI: Built with SvelteKit 5 + Tailwind CSS + DaisyUI for a responsive and smooth experience.
  • MCP Support: Fully compatible with Model Context Protocol for AI agent integration.
  • 8 Question Types:
    • Single Choice - Radio button selection
    • Multiple Choice - Checkbox selection
    • Remove Extra - Identify and select incorrect items
    • Order - Drag-and-drop reordering
    • Match - Click-to-match pairs
    • Text - Free-form textarea input
    • Input - Single-line text input
    • Input List - Dynamic list of text inputs
  • Flexible Configuration: Theme, timer, shuffling, progress indicators, and more.
  • CLI Tool: Easy-to-use command line interface for local testing and usage.
  • i18n Ready: Built-in internationalization support (English, Spanish, Russian, Ukrainian).
  • Storybook: Component documentation and development.

Local-first & Privacy by Design

Quiz MCP runs entirely on your machine.

  • No external APIs
  • No cloud services
  • No telemetry
  • No user data leaves your system

AI agents communicate with the quiz UI through a local MCP server. All interactions stay within your local environment (unless you explicitly configure a webhook).

Installation

pnpm install
pnpm build

Usage

CLI Commands

Quiz MCP provides two CLI commands:

quiz run

Run interactive quizzes via CLI with browser interface.

Usage:

node bin/quiz-mcp run [options]

# Run a quiz from a URL
node bin/quiz-mcp run --url "https://raw.githubusercontent.com/karerckor/quiz-mcp/main/quiz-examples/javascript-fundamentals.jsonc"

Try Example Quizzes

You can run the example quizzes directly from the GitHub repository without cloning:

# Run JavaScript Fundamentals quiz (via npx)
npx quiz-mcp run --url "https://raw.githubusercontent.com/karerckor/quiz-mcp/main/quiz-examples/javascript-fundamentals.jsonc"

# Run Web Development quiz (via pnpx)
pnpx quiz-mcp run --url "https://raw.githubusercontent.com/karerckor/quiz-mcp/main/quiz-examples/web-development.jsonc"

# Run with auto-open browser
npx quiz-mcp run --url "https://raw.githubusercontent.com/karerckor/quiz-mcp/main/quiz-examples/javascript-fundamentals.jsonc" --open

quiz mcp

Run as MCP server for AI agent integration.

Usage:

node bin/quiz-mcp mcp [options]

Options:

OptionDescription

Running with Package Managers

Quiz MCP can be run directly with npx, pnpx, or bunx without manual installation:

# Using npx (npm)
npx quiz-mcp run --file ./my-quiz.json

# Using pnpx (pnpm)
pnpx quiz-mcp run --file ./my-quiz.json

# Using bunx (bun)
bunx quiz-mcp run --file ./my-quiz.json

# Run MCP server
npx quiz-mcp mcp
pnpx quiz-mcp mcp
bunx quiz-mcp mcp

# Run a quiz from URL (try example quizzes)
npx quiz-mcp run --url "https://raw.githubusercontent.com/karerckor/quiz-mcp/main/quiz-examples/javascript-fundamentals.jsonc"
pnpx quiz-mcp run --url "https://raw.githubusercontent.com/karerckor/quiz-mcp/main/quiz-examples/web-development.jsonc"

Standalone Mode (CLI)

Run a quiz directly from a local JSON file:

# Run a JavaScript quiz
pnpm quiz:js

# Run a Web Development quiz
pnpm quiz:web

Or run any custom file:

node bin/quiz-mcp run --file ./my-quiz.json --open

MCP Mode (AI Agent)

Start the MCP server to allow AI agents to connect:

node bin/quiz-mcp mcp

The server runs on port 3000 (default) or the port specified in your configuration.
