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.

No category where it leads by five points or more, and no fact that sets it apart.

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
