by jimmcq • Workflow & Task Management

A lightweight MCP server that implements a playable Lemonade Stand game for Claude Desktop, demonstrating how models can interact with external tools and maintain state.

Example Use Cases

1
A stateful, interactive demo environment to practice calling MCP tools and managing multi-step workflows.
2
Test decision-making strategies around pricing, inventory, and demand under changing conditions (e.g., weather-driven demand).
3
An example implementation to learn how to expose and use MCP tools (start_game, buy_supplies, set_price, sell_lemonade, next_day) in Claude Desktop integrations.

Description

This Node.js MCP server provides a full 14-day Lemonade Stand business simulation (weather, supply chain, pricing, inventory, and daily sales) that Claude Desktop can call as tools. It exposes actions like start_game, buy_supplies, set_price, sell_lemonade, get_game_state, and next_day so agents can make decisions and observe results. It's useful as a hands-on example and testbed for building MCP integrations, teaching MCP concepts, or prototyping agent-driven interactions with external systems.
