## 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 70
- Schema & documentation, 87 against 53
- Security & auth, 83 against 69
- Payments & pricing, 20 against 10
- Transparency & trust, 74 against 63

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

### WorkOS Pipes and Agents (C)

Good for: Best when WorkOS already runs SSO or AuthKit and the agent needs users' or organisations' tokens for many SaaS providers plus its own revocable identity.

Watch for: 21 incidents on the status page since 3 July 2026, several over an hour

## 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.

**WorkOS Pipes and Agents.** Agent identity with per-session revocation and token lifetimes set per blueprint. 21 incidents on the status page since 3 July 2026, several over an hour.

## 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

### WorkOS Pipes and Agents

1. Call POST /data-integrations/{provider}/token with user_id for each use and don't cache the token
2. Branch on `active` in the response and send the user to reconnect on `needs_reauthorization`
3. Wait for Retry-After on a 429, or back off with jitter when it's missing
4. Use lower-case provider slugs such as github or slack
5. Revoke an agent's session through the Agents API when a task ends instead of waiting for expiry
