Description

This project provides a Model Context Protocol (MCP) server that integrates with Microsoft 365 via the Microsoft Graph API, supporting a wide range of personal and organization-level tools (Outlook, Calendar, OneDrive, Excel, OneNote, To Do, Planner, Teams, SharePoint, etc.). It includes multiple authentication modes (device code flow, OAuth HTTP mode, and bring-your-own-token), token caching, read-only mode, and fine-grained tool filtering. Organization mode enables work/school features like Teams and SharePoint, while HTTP mode exposes OAuth endpoints for client-managed authentication.
