## Which one, for what

### Microsoft Entra Agent ID (BB)

Good for: Organisations already on Microsoft Entra that want each agent to be a governed directory identity with tokens for Microsoft Graph, Azure and their own APIs.

Ahead on:
- Reliability, 91 against 73
- Schema & documentation, 87 against 64
- Agent ergonomics, 71 against 65
- Security & auth, 83 against 66
- Maintenance & community, 80 against 62
- Transparency & trust, 74 against 66

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: Conditional Access, ID Protection and governance for agents need Microsoft Agent 365, listed at $15 a user a month on yearly billing

### Stytch Connected Apps (C)

Good for: A team that needs an OAuth 2.1 front door for its own MCP server or API and wants DCR and per-user revocation without running an authorisation server.

Watch for: No outbound token vault, so it can't hold your users' third-party tokens

## Verdicts

**Microsoft Entra Agent ID.** Agent identities hold no credentials of their own, and Entra refuses high-privilege roles and Graph permissions for them. The token flow is a two-step exchange that Microsoft's own docs call complex and error-prone to implement by hand, and Conditional Access, risk detection and governance for agents need a paid Agent 365 licence.

**Stytch Connected Apps.** OAuth 2.1 authorisation server with DCR, CIMD and PKCE out of the box. No outbound token vault, so it can't hold your users' third-party tokens.

## Before you call either

### Microsoft Entra Agent ID

1. Request tokens in two steps. The blueprint gets an exchange token with fmi_path set to the agent identity's client ID, then the agent identity trades it for a resource token
2. Retry with exponential backoff when a create returns `400 Object with id not found` straight after creating its parent object
3. Send displayName, agentIdentityBlueprintId and a sponsor reference when creating an agent identity. All three are required
4. Don't use the interactive `/authorize` flow. Agent identities are confidential clients and can't sign in to a page
5. Keep the sidecar off any public network. Its `/AuthorizationHeader` endpoint hands out tokens to whoever can reach it

### Stytch Connected Apps

1. Fetch `{project-domain}/.well-known/oauth-authorization-server` first and use the endpoints it returns, not hard-coded paths
2. Register with `token_endpoint_auth_method` none and PKCE S256 when the agent can't keep a secret
3. Expect a 401 with protected resource metadata from the MCP server, then register and authorise
4. Ask only for scopes the user's roles can grant, or the consent page will refuse them
5. Back off exponentially on a 429, since no Retry-After header is documented
