Hated WoW MCP

An MCP server for writing World of Warcraft addons. Free and open source. It gives your AI assistant three things it otherwise guesses at: the in-game Lua API for the client you are targeting, Blizzard's own shipped UI source so it can see how the game itself does something, and the game's art and file data so texture references are real rather than invented. Its 20 documented tools cover wow, api, file.

People who work with wow, api and file and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
