Which one, for what

Aembit BB

Good for A security team that wants one policy and audit point between AI agents or workloads and the services they call, with credentials kept away from the agent.

Ahead on

  • Payments & pricing, 40 against 30
  • Maintenance & community, 80 against 70

Watch for

No rate limit figures in the reviewed documentation. The Edge API lists 429 responses without limits or Retry-After guidance

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 65
  • Transparency & trust, 75 against 60

Also in its favour

  • A hosted endpoint, with nothing to install

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.

Verdicts

Aembit

Agents and workloads get short-lived credentials by attestation, and MCP clients sign in through OAuth 2.1 with policy checked on every request. Both APIs have public OpenAPI files. No rate limit figures or SLA are published, the managed gateway endpoint is requested through an Aembit representative, and no DPA or sub-processor list was found.

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.

Before you call either

Aembit

  1. Read the API Base URL and token from the tenant's Profile page. Tokens last 1 hour by default, so plan to refresh
  2. Send X-Aembit-ResourceSet on Cloud API, Edge API and MCP calls outside the default Resource Set, or the request runs against the default set
  3. Cache the Edge API access token from /edge/v1/auth until near expiry before calling /edge/v1/credentials. Both endpoints can answer 429
  4. Point MCP clients at https://<gateway-host>/mcp. The /me path is deprecated
  5. Expect tool names prefixed with the Server Workload name behind the MCP Identity Gateway, and keep perPage at 100 or less on the Aembit MCP Server

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.
