Overview

This server integrates Claude with the Microsoft Graph API and Power Automate, providing a suite of tools for managing Outlook emails, calendars, and folders. Users can search for emails, create calendar events, and manage folder structures directly within their AI-powered workflows.

It also interfaces with Power Automate to list, trigger, and monitor the execution history of your automated flows.

Our verdict

With a security score of 31/100, this server carries a high risk profile. Specifically, the repository lacks a defined software license, leaving legal usage terms unclear, and the authentication and read-only mechanisms have not undergone external review. Given these factors and the community-maintained status, this tool should only be used by developers who are comfortable reviewing the source code and handling their own authentication security in a non-sensitive environment.

  • Supports broad Microsoft 365 service integration via Graph API
  • Contains only two direct dependencies for lower supply-chain surface
  • Provides documented functionality for Power Automate flow management
  • No license detected, creating ambiguity regarding legal usage terms
  • Authentication and read-only mode have not been externally reviewed
  • Community-maintained project with no official vendor support
