What the publisher says
From the Outlook Mac repository's README, as published. We do not edit it. Read it on GitHub
outlook-mac-mcp
<!-- mcp-name: io.github.valter-araujo/outlook-mac-mcp -->
MCP server for Microsoft Outlook, built for personal Microsoft accounts (Hotmail, Outlook.com, Live) that run on the consumer infrastructure rather than Exchange Online — and are therefore not supported by the official "Claude for Outlook" add-in nor by the Microsoft 365 connector.
Backend: Microsoft Graph API with delegated, user-consented, least-privilege scopes. Python, transport stdio, no telemetry.
Why not AppleScript
Community MCP servers for Outlook on Mac drive the app through AppleScript. That path only works with Legacy Outlook. In August 2026 Microsoft cancelled the planned AppleScript support in New Outlook, and the transition to New Outlook ends in October 2026. This project deliberately does not depend on it.
The reference environment for this project runs New Outlook (the "Legacy Outlook" toggle is present in the Outlook menu), where AppleScript automation is unavailable. This was the deciding factor.
Technical requirements
Runtime
Microsoft account and app registration
offline_access, openid and profile are reserved scopes: MSAL appends them to every request on its own and raises if they are passed explicitly. They are consented at the registration but never appear in the list the code asks for — that consent is what yields the refresh token behind the Keychain cache.
The app registration may list broader permissions than the server requests. The token only ever carries the scopes the running configuration asks for: the write scope is requested only behind a config flag that is off by default, and turning it on triggers a new sign-in and consent prompt.
Not required
- Microsoft Outlook desktop app (the server talks to Graph, not to the app)
- Exchange Online / Microsoft 365 business tenant
- Accessibility or Automation permissions on macOS
- Node.js, Bun, or any non-Python runtime
