Connect Claude & ChatGPT to Google Chat

Ask your AI what was said in a space today, to post an update to your team, or to set up a new space with the right people. It lists your spaces and direct messages, reads messages and reactions, sends, edits and deletes messages, and adds or removes members. You catch up on a busy space without scrolling back through it.

Try asking

“What was discussed in the Marketing space today?”
The AI finds the space, lists today's messages and sums them up with who said what.
“Post in the Sales space: the new price list is ready.”
It sends the message to the space as you. Everyone in the space can see it.
“Reply in that thread that I will look at it tomorrow.”
It posts your reply in the same thread instead of starting a new one.

What your AI can do

Spaces

List your spaces, group chats and direct messages, read a space's details, create or set up spaces and update their name and description.

Messages

List and read messages with their threads and attachments, send messages or thread replies, edit or delete your messages and react with emoji.

Members

List the members of a space, read a membership and role, and add or remove people.

“Set up a space called Project Falcon with Maria and Peter.”
It creates the space and adds both people in one step. They are notified.
“Who is in the Support space?”
It lists the members of the space with their roles.
“Do I already have a direct message with [email protected]?”

Set up in three steps

1
Pick the app
Create a free HeyMyApps account and choose Google Chat from the app list.
2
Paste your key
Paste the OAuth client ID and client secret from your own Google Cloud project, then sign in with Google once. In the Google Cloud console create a project and enable the Google Chat API. On the Chat API's Configuration tab fill in an app name, avatar URL and description, because Chat requires this even for user access. Set up the OAuth consent screen, then under Credentials create an OAuth client ID of type Web application with the redirect URI https://heymyapps.com/oauth/callback and copy the client ID and secret. Google Chat works with Google Workspace accounts only.
3
Add the link to your AI
You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:
1. Click your name, then Settings › Connectors › Add custom connector.
2. Paste your link as the Remote MCP server URL.
3. Switch it on from the + menu in a chat.

Questions

What can the AI do in Google Chat?

It can list your spaces and direct messages, read a space, its messages, reactions, members and attachment details, and find your direct message with a person. It can create and set up spaces, update a space's name and description, send, edit and delete messages, react to messages, and add or remove members.

Does the AI see my Google Chat credentials?

No. Your OAuth client secret and the access from your Google sign-in are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with reading only. Sending a message reaches real people and deleting a message cannot be undone, so these can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

Google Chat connects with OAuth, and OAuth connections need the HeyMyApps Pro plan or above. HeyMyApps also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own Google Workspace account.

Does it work with a personal Gmail account?

No. Google Chat access through the API works with Google Workspace accounts only. You also need to fill in the Chat API's Configuration tab in your Google Cloud project before you sign in.
