## 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.
