An admin connects Chui to the company's Claude once; colleagues have it with no sign-in.
If your company uses Claude Team or Enterprise, an admin can turn Chui on for everybody at once. Every colleague who has joined the company in Chui, with the same email as their Claude account, then finds Chui already working in Claude: they do not search for it, sign in or approve anything, and they stay connected. Somebody who has not joined yet must do that once first; the card in Chui lists who that is. It takes about five minutes, and you need to be an admin of the company in Chui and an Owner or Primary Owner of the organisation in Claude. Colleagues who are not ready yet can still connect by signing in themselves.
Each colleague reaches only what they can already read in Chui: their own company account, and nothing from any personal account.
1. In Claude, open Organization settings › Connectors and find Chui. Press Set up auto-connect, or Set up beside Managed authorization on its Configuration tab. If neither is there yet, add https://mcp.chui.io as a custom connector on the same page and open it: Managed authorization is on its Configuration tab. Choose Claude-issued under Identity source. 2. Copy the Issuer URL Claude shows. It starts https://identity.anthropic.com/issuers/. 3. In Chui, open Settings › Members › Claude for the whole company, paste the address and press Turn on for the company. 4. Copy the company ID Chui now shows, and paste it into Tenant ID in Claude's setup. This names your company in everything Claude sends, so nobody else who types your address into their own company can get in the way. 5. In Claude, press Test connection, then Enable and continue, and choose which roles get Chui.
By typing, it is get_claude_for_company(), then prepare_turn_on_claude_for_company() with the address and turn_on_claude_for_company() with the token it gives.
Three things must all be true, and an address that merely ends in your domain is not one of them:
Anybody else is refused, and Claude offers them the ordinary sign-in. So invite your colleagues to Chui first; turning this on adds nobody to the company.
Only trust a Claude organisation your company runs: whoever controls it decides who is a member of it.
Press Turn off on the same card, or use turn_off_claude_for_company(). Every connection it made ends at once, and colleagues can still connect by signing in themselves. Removing somebody from your company ends theirs at once too. Removing somebody from the Claude organisation ends it within the hour.
If the company has locked Claude and ChatGPT off under Company settings, this cannot be turned on until that lock is lifted.
