Outlook

A local MCP server that connects an assistant to Microsoft Outlook for message search, batch operations and calendar management, using Microsoft OAuth.

What you can do

Search and work with Outlook email messages, including batch operations across several messages at once. Manage calendar entries such as events and appointments. Authenticate to Microsoft through OAuth, with configurable client, tenant and redirect settings. Export data to CSV files through a configurable resource store.

When to use it

Useful when you want an assistant to read, search or act on a Microsoft Outlook mailbox and calendar from your own machine, rather than through a hosted service.

Requirements

Runs locally as an npm package via npx, so Node.js is needed. A Microsoft OAuth app registration is required: MS_CLIENT_ID and MS_TENANT_ID are required, and MS_CLIENT_SECRET is optional for public clients. Several optional environment variables configure auth mode, base URL, dynamic client registration, headless login, port, redirect URI and CSV export storage.
