outlook-mcp

MCP server for Microsoft Outlook personal accounts (Outlook.com, Hotmail, Live). Provides AI agents with full access to mail, calendar, contacts, and tasks via Microsoft Graph API.

Independent open-source project. Not affiliated with Microsoft.

Important

• Personal Microsoft accounts only (@outlook.com, @hotmail.com, @live.com). Work/school accounts (Entra ID) are not supported in v1.
• Requires Azure AD app registration — free, takes ~5 minutes, but you need a free Azure account first. See README.
• Auth is CLI-based — run outlook-mcp auth on the host before the agent can use it. No interactive auth through MCP tools.
