About MCP-Microsoft-Office
Aanerud/MCP-Microsoft-Office
an local MCP server you can run on your env, connecting you to Microsoft Graph, and the complete M365 eco system.
Implements a three-tier architecture with a Node.js MCP adapter translating JSON-RPC protocol to HTTP requests, enabling 117 tools across Mail, Calendar, Files, Excel, Word, and PowerPoint with per-user Graph API authentication.
