Dungeon Fighter Online for AI agents

Dungeon Fighter Online is a side-scrolling action RPG where players build characters, gear, and skills to battle through dungeons, with an API exposing character and item data. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.
