Connect your Summer account to Claude or ChatGPT. Then ask, in your own words:
  • “Who of my friends is online?”
  • “Text my friends and ask who wants to play.”
  • “Invite them to Star Weavers.”
  • “Tell me when Ana accepts.”
  • “Send Leo a rival request.”
  • “Take me to the store page for Star Weavers.”
The AI app does it as you. It uses the Summer Games MCP at this address:

​
Connect Claude

You add Summer once, on the web or in Claude Desktop. It then works in every Claude app with the same Claude account, the phone too.
1

Add the connector

On claude.ai or in Claude Desktop, open Settings → Connectors and choose Add custom connector.
2

Paste the address

Name it Summer and paste https://mcp.summer.games/mcp. Choose Add.
3

Sign in on summer.games

Claude opens summer.games. Sign in to your Summer account, check the app name and the site it sends you back to, and choose Allow.
4

Use it in a chat

In a new chat, ask “Who of my friends is online?”. If Claude does not use Summer, turn the connector on with + → Connectors.
On your phone: open the Claude app on iPhone or Android, signed in to the same Claude account. Summer is already there. You cannot add a custom connector in the phone app itself, so add it on the web or desktop first. Your Claude plan must allow custom connectors. On a Team or Enterprise plan, an owner adds the connector for the organization first, then each member connects.

​
Connect ChatGPT

1

Turn on developer mode

On chatgpt.com, ChatGPT asks you to turn on developer mode before you add a custom MCP server. Where this setting lives, and which plans have it, changes. Check OpenAI’s help if you do not see it.
2

Add Summer

Add a custom MCP server (connector) with the address https://mcp.summer.games/mcp and OAuth sign-in.
3

Sign in on summer.games

ChatGPT opens summer.games. Sign in, check the app name and the site, and choose Allow.
On your phone: we have not tested the ChatGPT phone app with Summer yet. Use chatgpt.com.

​
Connect Claude Code or another app

Claude Code:
Then run /mcp in Claude Code and choose summer to sign in. Any other AI app: add a remote MCP server with the address above. The app must support OAuth sign-in. It registers itself with Summer when you connect.

​
What you choose when you connect

The summer.games page shows what the app asks for: Act always includes read. Your AI app asks you before it sends or changes anything. Read what it is about to send before you say yes.

​
Things to ask

See every tool on Summer Games MCP tools.

​
Cards in the chat

Claude and ChatGPT show Summer answers as cards, right in the chat: The party card stays live while it is on screen. When a friend joins, it posts a short note to the chat, “A friend joined my Summer party. The game is ready. Check my party.”, and the AI app tells you who joined. Play opens your party on summer.games. An app that does not show cards gives you the same answer as text. Every answer also carries summer.games links to the Games, players, chats, parties and invites it names.

​
Hear when a friend accepts

You do not have to keep asking. Summer tells you in the way your app supports:
  • Claude: the party card shows the join while the chat is open, as above.
  • ChatGPT: ask “Tell me when Ana accepts my invite.” ChatGPT watches for it and tells you when it happens. It also works for friend requests, messages and rival requests.
  • Any app: the next question you ask (“did Ana accept?”) reads the latest state.
Event news carries names and a link, never message text. Your app reads the messages with a tool, so you see them in full.

​
Rivals

A rival is a player you both agreed to compete with. It works like a friend request: one player sends a rival request, the other accepts or declines. Player against player only. A rival does not have to be your friend.
  • “Send Leo a rival request for Patchwork.”
  • “Who are my rivals?”
  • “Am I ahead of Leo in Patchwork?” compares your playtime, when you last played, and your places in the Game’s rankings.
  • “End my rivalry with Leo.”
Only you and your rival see the comparison. A block ends the rivalry.

​
Move the desktop app

In the latest Summer Games desktop app, open and signed in on your computer, your AI app can bring the app to the front on a page: a Game’s store page, your library, downloads, friends, a player’s profile, your party, messages, inbox, Passport, Sparks or settings.
  • “Take me to the store page for Star Weavers.”
  • “Open my messages with Ana in the Summer app.”
It only shows the page. It never presses a button there, and buying stays with you in the app. When the desktop app is not running, you get the summer.games link instead. If nothing opens, update the desktop app.

​
Coming soon

  • Phone alerts. The Summer Games app on iPhone and Android will show an alert for new messages, party invites, and when a friend joins your party. Until then, your friends see invites and messages in their Summer inbox.

​
Privacy and control

  • It acts as you. Messages, friend requests and invites it sends look exactly like the ones you send yourself. Nobody is told an AI app sent them. The Community Standards apply to them as they do to you.
  • The same rules apply. Messages go only to friends. Blocks apply. An app can use at most half of your account’s limits, so your Summer apps keep working.
  • The AI app sees what it reads. When it reads your friends, messages or party, that information goes to the AI app and the company that runs it.
  • Players under 13 have no friends, messages or parties on Summer, so a connected app cannot use them on those accounts.
  • Only allow apps you trust. Anyone can give an app any name. The sign-in page shows the site the app sends you back to. Check it.

​
Disconnect

Open Settings → Connected apps on summer.games. It lists every app you connected, when you connected it and when it was last used. Choose Disconnect, and the app stops at its next request. If an app says Summer signed it out, or you have not used it for 30 days, connect it again.

​
What it cannot do

These stay in the Summer apps, where you do them yourself:
  • Buy anything, or buy or spend Sparks.
  • Close or delete your account.
  • Block, unblock or report players.
  • Change family or parent settings.
  • See or change your other connected apps.
  • Play a game for you, join a queue, or do anything inside a running game.
