Amazon Bedrock AgentCore Gateway offers IAM and JWT authorization for agent tools

Amazon Bedrock AgentCore Gateway offers two primary methods for authorizing agent tools: AWS IAM and CUSTOM_JWT. The AWS IAM approach is suitable for internal use within an AWS account, where agents sign requests with AWS credentials, simplifying security by avoiding token management. For external access, such as partners or multi-tenant services, the CUSTOM_JWT method requires callers to present a valid JSON Web Token validated against an external identity provider, ensuring secure access without granting broad AWS permissions.
