AWS IAM

Claude Platform on AWS natively supports AWS IAM authentication, allowing enterprises to use their existing permission management systems to control access to the Claude API.

IAM, represented by AWS IAM, follows the principle of least privilege, where each principal is granted only the minimum set of permissions required to complete a specific task.

Configuring Monitor on Bedrock requires ensuring that IAM permissions cover the monitoring-related interfaces.

The keychain is not a panacea: once the local account is compromised, an attacker may still be able to invoke the keychain as the current user, so it should be combined with least-privilege IAM users and regular rotation of access keys.

Mainstream IAM platforms such as Okta, Azure AD, and AWS IAM typically record every authentication and permission-use event.

To connect an existing bucket, it is usually necessary to manually adjust the bucket policy and role permissions in the AWS console, and then explicitly pass the bucket name and role ARN via environment variables.

The roleArn and the conditions in the role trust policy on the AWS side (such as the allowed OIDC issuer, audience, and project identifier) must match strictly, otherwise the credential exchange will fail.

The reason existing buckets cannot be onboarded is that the integration relies on the IAM role trust relationship and resource naming conventions established synchronously when resources are created on the Vercel side.

Calling Amazon Bedrock requires the IAM permission bedrock:InvokeModel, and each model must be explicitly requested for activation in the target region.

Failures at the deployment stage usually come from insufficient IAM permissions or the model not being enabled in the target region, with direct error messages and fast localization; runtime failures, by contrast, often stem from a certain account simply not having accepted the MPPO, in which case application calls to Bedrock receive authorization-type errors, but the error message does not necessarily point directly to the missing Marketplace entitlement.

On the AWS side, JalOS uses EC2 for hosting, IAM for access control, Systems Manager Parameter Store for configuration management, S3 for storing deployment artifacts and model files, CloudWatch for log collection, and Systems Manager Run Command for executing deployments.

By combining AWS IAM's Service Control Policies (SCP), platform teams can set maximum permission boundaries at the organizational layer such that even project-layer administrators cannot break through the compliance constraints set at the organizational layer.

Hosting the MCP server on AgentCore allows reuse of its deep integration with AWS IAM, enabling secure access to target production accounts via cross-account IAM role trust relationships and avoiding the risk of hardcoded credentials.

Cross-account role assumption obtains temporary credentials for a target account's IAM role by calling STS's AssumeRole API, with temporary credentials typically valid for 15 minutes to 1 hour.

For workloads running on AWS (M2M scenarios), it is recommended to use cross-account SigV4 signing combined with cross-account role assumption for authentication.

AWS IAM and OAuth 2.0's delegated authorization flows are typical implementations of identity and access management.

The concept of declarative policies has been widely adopted in the infrastructure domain (e.g., AWS IAM policies, Kubernetes RBAC), but remains in an early stage at the AI agent layer.

Key rotation refers to periodically replacing access credentials to reduce the risk of long-term credential exposure, and tools such as AWS IAM and HashiCorp Vault have standardized this practice.

Cognito's User Pool handles authentication functions such as user registration, login, and password management, while the Identity Pool is responsible for mapping authenticated users to AWS IAM temporary credentials.
