Overview

An MCP server for interacting with Microsoft 365 services (Outlook, Teams, SharePoint, etc.) via the Graph API, supporting personal and organizational accounts.

This MCP server offers a balance of read and write capabilities for Microsoft 365 services. It's relatively safe in read-only mode or when used with personal accounts. However, enabling organization mode and using tools that modify data requires careful permission management and awareness of potential risks.

Performance depends on the number of API calls made to Microsoft Graph and the size of the data being processed. Consider using pagination and filtering to optimize performance.

Cost is primarily determined by the number of API calls made to Microsoft Graph. Be mindful of Graph API usage limits and throttling policies.
