Microsoft Entra Agent ID (preview) for creating OAuth2-capable AI agent identities via Microsoft Graph beta API. Covers Agent Identity Blueprints, BlueprintPrincipals, Agent Identities, required permissions, sponsors, and Workload Identity Federation. Includes Microsoft Entra SDK for AgentID (containerized sidecar) for polyglot agent authentication (Docker/Kubernetes), 3P agent integration, autonomous and interactive agent patterns. Triggers: "agent identity", "agent id", "Agent Identity Blueprint", "BlueprintPrincipal", "entra agent", "agent identity provisioning", "Graph agent identity", "entra sidecar", "agent id sidecar", "auth sidecar", "3P agent", "third-party agent identity", "polyglot agent auth".
Create and manage OAuth2-capable identities for AI agents using Microsoft Graph beta API.
Preview API — All Agent Identity endpoints are under
/betaonly. Not available in/v1.0.
Search microsoft-docs MCP for the latest Agent ID documentation:
One of: Agent Identity Developer, Agent Identity Administrator, or Application Administrator.
⚠️
DefaultAzureCredentialis NOT supported. Azure CLI tokens containDirectory.AccessAsUser.All, which Agent Identity APIs explicitly reject (403). You MUST use a dedicated app registration withclient_credentialsflow or connect viaConnect-MgGraphwith explicit delegated scopes.
Sponsors are required and must be User objects — ServicePrincipals and Groups are rejected.
This step is mandatory. Creating a Blueprint does NOT auto-create its service principal. Without this, Agent Identity creation fails with:
400: The Agent Blueprint Principal for the Agent Blueprint does not exist.
If implementing idempotent scripts, check for and create the BlueprintPrincipal even when the Blueprint already exists (a previous run may have created the Blueprint but crashed before creating the SP).
| Operation | Method | Endpoint | OData Type |
|---|---|---|---|
| Create Blueprint | POST | /applications | Microsoft.Graph.AgentIdentityBlueprint |
| Create BlueprintPrincipal | POST | /servicePrincipals | Microsoft.Graph.AgentIdentityBlueprintPrincipal |
| Create Agent Identity | POST | /servicePrincipals | Microsoft.Graph.AgentIdentity |
| List Agent Identities | GET | /servicePrincipals?$filter=... | — |
| Delete Agent Identity | DELETE | /servicePrincipals/{id} | — |
| Delete Blueprint | DELETE | /applications/{id} | — |
All endpoints use base URL: https://graph.microsoft.com/beta
| Permission | Purpose |
|---|---|
Application.ReadWrite.All | Blueprint CRUD (application objects) |
AgentIdentityBlueprint.Create | Create new Blueprints |
AgentIdentityBlueprint.ReadWrite.All | Read/update Blueprints |
AgentIdentityBlueprintPrincipal.Create | Create BlueprintPrincipals |
AgentIdentity.Create.All | Create Agent Identities |
AgentIdentity.ReadWrite.All | Read/update Agent Identities |
There are 18 Agent Identity-specific Graph application permissions. Discover all:
Grant admin consent (required for application permissions):
Admin consent may fail with 404 if the service principal hasn't replicated. Retry with 10–40s backoff.
