Microsoft 365 MCP servers: which one to use
Use Microsoft's Work IQ if your IT admin will approve it. If not, use the community Softeria server, and turn on its read-only flag first.

Microsoft's Work IQ is the official way to let an assistant work with your Microsoft 365 mail, calendar, files and Teams chats. An IT admin has to approve it, it blocks changes until an admin allows them, and use is billed in Copilot Credits. The community servers skip the admin step. Softeria's covers mail, calendar, OneDrive and more with your own sign-in, and others focus on Teams or tenant administration. Whichever you pick, these can send mail and delete data as you, so start read-only.
Good for
- Office workers who want Claude to search mail, meetings and files across Microsoft 365
- IT admins who need an assistant to query security, audit and device data
- Teams users who want unread chats and threads summarized
- Anyone who wants an assistant to read their mailbox without sending or deleting
Which Microsoft 365 MCP server to use
Use Work IQ if your company already pays for Copilot Credits and your admin approves it. Pick Softeria's server for personal or small-team use, and Microsoft 365 Admin only if you manage a tenant.

Questions
Is there an official Microsoft 365 MCP server?
Yes. Work IQ is Microsoft's official server for Microsoft 365, covering mail, calendar, OneDrive and SharePoint files, and Teams. The other servers in the table are community projects.
Do I need my IT admin to use Work IQ?
Yes. The Work IQ readme says it needs permissions that require admin consent on the tenant, and a non-admin has to ask a tenant administrator. The community servers use your own sign-in, though your tenant may still limit them.
Which Microsoft 365 MCP server can be read-only?
Softeria's server has a --read-only flag, and Microsoft 365 Admin is read-only by default until you pass --allow-writes. Work IQ blocks create, update and delete requests by default until an admin enables them in tenant policy.
Can it send email or delete things?
Yes. Softeria's server can send mail and delete data as you. Work IQ can too, once your admin enables those requests in tenant policy, because it blocks them by default.
Does Work IQ cost money?
Yes. Microsoft says Work IQ is paid per use through Copilot Credits, billed to your organization. Ask your admin how your tenant is set up.
Does it work with Claude?
Microsoft's Work IQ docs show setup for GitHub Copilot CLI, Foundry and Copilot Studio and do not mention Claude. Softeria's server has a Claude Desktop setup in its install box.
Do I need to register an Azure app?
Not for Softeria's server by default, which uses a built-in app and a device-code sign-in. Microsoft 365 Admin needs an app registration with application permissions. msteams-mcp says it needs no Azure setup.
Does it work with Teams?
Yes. Work IQ covers Teams chats. Softeria's server covers Teams if you start it in organization mode, and msteams-mcp is built only for Teams.
What is the Work IQ MCP server URL?
https://workiq.svc.cloud.microsoft/mcp. You sign in with your Microsoft work account. There is also a local version you can run with npm.
Does Microsoft have other hosted Microsoft 365 MCP servers?
Yes. Microsoft's Agent 365 list includes hosted Mail, Calendar, Teams, SharePoint, OneDrive and Word servers in preview. Microsoft says they are kept for backward compatibility and testing, and tells new projects to use Work IQ instead.
