Microsoft Teams MCP: connect Teams to Claude and ChatGPT
Ask Claude or ChatGPT what the project channel agreed on Friday, what Erik said about the budget in your chat or which thread has the final delivery date. The answer comes from Teams, with a link to every message it relies on.
With Deployed OS everyone connects with their own work account. The AI searches and reads the chats and channels that person is in, and it posts only when they ask and have confirmed where and the exact text.

Who sees what
- Reads chats and channels, posts as you
- The connector searches and reads your chats and the channels of the teams you belong to. It can post a plain-text message to a chat, channel or thread as you, and only for people with Edit access.
- Each person’s own work account
- Everyone connects their own Microsoft work account, so the AI sees the chats and teams that person is in. A chat you are not part of is never read.
- You choose who gets it
- Admins decide which groups get the Teams connector, and which of those may post. Everyone else never sees it.
- Every call logged
- Who asked, which connector, when. Deployed OS shows reads and writes per connector and per person, and the log can be exported.
Set up the Microsoft Teams connector in three steps
Microsoft Teams’s own MCP server or Deployed OS?
Microsoft publishes a Teams MCP server of its own as part of Work IQ, in preview. It is built for agents in Copilot Studio and Microsoft Agent 365, and reads and writes chats, channels and messages. For a team building agents on Microsoft’s own platform, it is the natural choice.
Deployed OS is for the whole company and the assistants people already use. Teams is one connection next to your CRM and other tools, each person is on their own work account, admins choose which groups get Teams and who may post, and every call is logged. The same connection works in Claude, ChatGPT and Copilot, next to your company’s skills and guardrails.
Microsoft Teams MCP: common questions
Yes. Microsoft publishes one as part of Work IQ, in preview, for agents built in Copilot Studio and Agent 365. Deployed OS gives the whole company one Teams connection in Claude, ChatGPT and Copilot, with each person’s own account, access per group and a log of every call.
Yes, a plain-text message as you, to a chat, a channel or a reply in a channel thread, and only after you have confirmed where and the exact text.

Yes. Reading Teams channels needs the ChannelMessage.Read.All permission, which only an administrator can consent to for the whole company. Without it nobody can connect Teams. Granting consent for every permission also spares each person the consent prompt.
Yes. One app registration in your Entra ID serves Teams, Outlook Mail, Outlook Calendar, OneDrive and SharePoint. You register it once and choose per connector which groups get what.
Yes. Deployed OS is your company’s own MCP, so the same Teams connection works in Claude, ChatGPT and Copilot. People keep the assistant they prefer.
