## 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 78
- Security & auth, 83 against 67

Also in its favour:
- Agent-ready, a grade of BB or better
- No incidents deducted, where Nango loses 5 points for them

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

### Nango (B)

Good for: A product that connects many users to many SaaS APIs and wants tokens, refresh, syncs and a per-tenant MCP surface in one place, with source you can read.

Ahead on:
- Payments & pricing, 40 against 20
- Maintenance & community, 90 against 80

Watch for: Audit trail only on Enterprise, and logs kept 15 days on every plan

## 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.

**Nango.** 1,000+ APIs with OAuth, API key and client-credentials auth handled. Audit trail only on Enterprise, and logs kept 15 days on every plan.

## 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

### Nango

1. Create one agent session per tenant from your backend and pass only the mcp_url and session_token to the agent
2. Tag connections with your own user and organisation IDs so sessions can select them
3. Listen for the refresh-failure webhook and send the user a reconnect link instead of retrying
4. Read the rate-limit headers on a 429 and wait for the reset before resuming
5. Run 0.71.6 or later when self-hosting, and keep the runner port off the network
