Microsoft Users

Microsoft Users Toolkit

The Microsoft Users toolkit connects to the Microsoft Graph API to expose user profile and organizational hierarchy data for Microsoft 365 work and school accounts. It enables LLM agents to look up users, resolve reporting relationships, and enrich context with org data.

Capabilities

• Self-identity lookup: Retrieve the authenticated user's own profile, including name, email, job title, department, office location, and tenant domain.
• User profile resolution: Look up one or more users by email address, UPN, or user ID; automatically optimizes single vs. batch Graph API calls to enrich calendar attendees or email participants with org metadata.
• Organizational hierarchy traversal: Fetch a user's direct reports (paginated) or their direct manager; handles top-level users with no manager gracefully.
• M365 accounts only: All tools require a Microsoft 365 work or school account — personal accounts (outlook.com, hotmail.com, live.com) are not supported.

OAuth

Authentication is handled via OAuth 2.0 through Arcade's Microsoft provider. See the Arcade Microsoft auth provider docs for configuration details.
