Summer Games MCP: play with friends
The Summer Games MCP lets an AI app act on your Summer account, as you. Ask it “who of my friends is online?”, “text my friends and ask who wants to play” or “invite them to Star Weavers”, and it does it. Claude and ChatGPT show the answers as cards in the chat, and tell you when a friend joins. You sign in on summer.games and choose what it may do.
