wtf is hayday-mcp-server?

hayday-mcp-server is a tool that gives an AI assistant live access to game data from HayDay, the farming mobile game made by Supercell. It uses the MCP protocol, a standard way for AI tools like Claude Desktop, Cursor, and VS Code extensions to call outside data sources, so once connected, your AI assistant can look up crops, animal products, machines, and level unlocks and use that information to help you plan your farm. The README is explicit that this is a read-only lookup tool, not a bot: it never sends inputs to the game and cannot play on your behalf, it just answers questions the way a wiki would. Under the hood, when the AI calls one of the tools, the server fetches fresh data from a community-run site called hayday.info and keeps it in memory for an hour to avoid hitting that site too often. Because the data is fetched live rather than baked into the code, it stays current automatically whenever Supercell updates the game. The server offers about a dozen tools, including searching items by name, getting full details on a specific product, listing all machines, pulling every product tied to a machine, finding what unlocks at a given player level, and ranking items by profit per hour so you can figure out what is worth growing or crafting next. Setup is a simple git clone followed by npm install and running the server with Node, after which it listens for connections from any MCP-compatible AI client using a small JSON config file. The data covers crops, trees, animal products, machine-made goods, level unlocks, and profit figures, but does not include recipe ingredient breakdowns, building upgrade costs, or data about derbies, boats, or the town feature. The project is released under the MIT license and states it is not affiliated with or endorsed by Supercell.
