Playing a private World of Warcraft server in the browser via a custom MCP

On October 3, 2026, a post on Reddit's LocalLLaMA subreddit described an effort to let an LLM play World of Warcraft inside a browser. According to the author, the first step was hosting his own World of Warcraft private server. He then built a client for it that runs in the browser on both PC and mobile and can be played for free at jankcraft.xyz.

On top of that client, he created a custom MCP and an agent harness that drives the browser client, sending signals to the game over a websocket so that an agent plays in place of a human. The harness is already live at jankcraft.xyz/agent.

The author says he is still working out some kinks, so the setup is not yet fully settled. On access, he notes that users with a cloud subscription can try it directly, while local models can connect as long as CORS is enabled in the browser.

That is the full extent of the single report available so far. It does not include any further details about the schedule, which models were used, or how well the agent actually performs in the game, and no other coverage of the project has appeared.
