This MCP server provides a natural language interface to execute any CLI for Microsoft 365 commands. It can parse and fulfill user requests by breaking them down into a sequence of CLI for Microsoft 365 commands (a chain) when necessary, enabling complex tasks to be accomplished as a series of steps. Through this capability, you can manage many different areas of Microsoft 365, including Entra ID, OneDrive, OneNote, Outlook, Planner, Power Apps, Power Automate, Power Platform, SharePoint Embedded, SharePoint Online, Teams, Viva Engage, and more. The server relies on the globally installed CLI for Microsoft 365; it does not perform authentication by itself and users must login using m365 login to provide the authentication context. Once authenticated, the MCP server uses the same context when running any tool. It exposes tooling for the Model Context Protocol (via m365GetCommands, m365GetCommandDocs, and m365RunCommand) to discover commands, fetch documentation, and execute commands with results and reasoning. The project also includes guidance for integrating the MCP server with VS Code, GitHub Copilot CLI, and Claude Desktop to simplify adoption and testing in common workflows.
