Manage Azure AD application registrations - create, update, and manage app permissions
AI agents use manage_azuread_apps to create or update resources in Microsoft 365 Core MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Microsoft 365 Core MCP Server environment.
The tool performs reversible modifications (create, update) to Azure AD applications and their permissions. While not destructive (no deletion mentioned), managing app permissions is a high-severity operation because misconfiguration could grant excessive access to sensitive Microsoft 365 resources, compromise security posture, or enable privilege escalation.
From the tool's definition Tool description states "create, update, and manage app permissions" for Azure AD application registrations. These are write operations that modify identity and access control configurations.
