AI agents in production require secure access to external services. Amazon Bedrock AgentCore Identity, available as a standalone service, secures how your AI agents access external services whether they run on compute platforms like Amazon ECS, Amazon EKS, AWS Lambda, or on-premises.
An earlier post covered AgentCore Identity credential management for AI agents. Running agents on compute environments like ECS raises two questions: How to build an application-owned Session Binding endpoint, and how to manage workload access token lifecycle?
This post implements Authorization Code Grant (3-legged OAuth) on Amazon ECS with secure session binding and scoped tokens. This post provides a working implementation with:
- Secure session binding that prevents CSRF and browser-swapping attacks
