Microsoft MCP

Microsoft MCP is an MCP server that connects AI assistants to the Microsoft Graph API, allowing users to interact directly with Microsoft 365 services including Outlook, Calendar, OneDrive, and Contacts. Designed for professionals, developers, and teams who rely on the Microsoft ecosystem, it enables language models to manage personal, work, and school accounts from a single interface. Users can inspect inboxes, compose drafts, reply to email threads, and forward attachments without switching windows. For scheduling, the server allows AI clients to check calendar availability, create or modify events, and accept or decline meeting invitations. File management tools let assistants browse directories, upload and download files, and search through OneDrive storage. Additionally, it provides contact lookup and unified cross-service search across messages, events, and documents. Because every operation accepts an account identifier, individuals managing multiple Microsoft accounts can direct their assistant to carry out tasks across distinct profiles while maintaining local token security and granular Graph API permission scopes.
