Which one, for what

Amazon Bedrock AgentCore Identity BB

Good for Agents already built on AWS, above all those on AgentCore Runtime or Gateway, where token retrieval is automatic and free of extra charge.

Ahead on

  • Reliability, 85 against 73
  • Schema & documentation, 88 against 64
  • Agent ergonomics, 76 against 65
  • Security & auth, 84 against 66
  • Payments & pricing, 30 against 20
  • Maintenance & community, 70 against 62
  • Transparency & trust, 75 against 66

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

No operation to revoke or delete one user's stored grant was found. forceAuthentication clears a refresh token, and AWS says it cannot detect a revocation made at the provider.

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.

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

Watch for

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

Verdicts

Amazon Bedrock AgentCore Identity

The service handles user-delegated, machine-to-machine and on-behalf-of token flows through one call, with IAM scoping, KMS encryption and published quotas. It only works inside an AWS account a person creates, the hosted consent portal needs an AgentCore Gateway, and no call to revoke one user's stored grant was found in the API reference.

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

Amazon Bedrock AgentCore Identity

  1. Get a workload access token first (GetWorkloadAccessTokenForJWT in production), then pass it as workloadIdentityToken to GetResourceOauth2Token or GetResourceApiKey.
  2. When GetResourceOauth2Token returns authorizationUrl instead of accessToken, send the URL to the user and call again with the same sessionUri after consent.
  3. For user-delegated flows, host an HTTPS callback, register it with UpdateWorkloadIdentity as an allowed return URL, and call CompleteResourceTokenAuth after checking the user's session.
  4. Ask for refresh tokens in the provider's own way, such as access_type=offline in customParameters for Google or the offline_access scope for Microsoft and Atlassian.
  5. Treat a returned token as possibly revoked. On a 401 from the resource server, retry with forceAuthentication set to true.

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
