Implement On-Behalf-Of Token Exchange for Multi-Tenant AI Agents
▶ The 2-minute explainer
Summary
This post provides an implementation guide for on-behalf-of (OBO) token exchange in multi-tenant agentic systems using Amazon Bedrock AgentCore Gateway. It details a complete setup with Okta, illustrating JWT claim transformations and audience binding for scalable, fine-grained access control.
Why it matters
Secure and scalable access control is critical for multi-tenant AI applications, and this guide provides a concrete technical solution for managing user identities and permissions effectively. It addresses a complex security challenge essential for enterprise AI adoption.
How to implement this in your domain
- 1Review the conceptual foundations of OBO token exchange and fine-grained access control for multi-tenant agents.
- 2Configure an identity provider like Okta to issue and manage tokens for your multi-tenant AI application.
- 3Implement Bedrock AgentCore Gateway interceptors to handle JWT claim transformations during token exchange.
- 4Establish audience binding mechanisms to ensure defense-in-depth security across different tenants.
- 5Test the OBO setup thoroughly to validate secure and correct access control for all tenant scenarios.
Who benefits
Key takeaways
- OBO token exchange is crucial for secure multi-tenant AI agent systems.
- Amazon Bedrock AgentCore Gateway facilitates fine-grained access control.
- JWT claim transformations are key to managing identity across hops.
- Audience binding enhances security and scalability in multi-tenant architectures.

SQLite Recursive CTE Powers Novel Ray Tracer Implementation
A new project demonstrates a ray tracer built entirely using SQLite's recursive Common Table Expressions, storing its state on disk. This unique approach allows other tools to query the ray tracer's state in real-time, exemplified by a custom HTML+JS minimap.
Claude Tag Enhances Expressive Artifacts and Collaborative Dashboards
The "Claude Tag" feature now allows for more expressive artifacts that can be creatively combined, enabling users to build collaborative project dashboards. These dashboards can be edited by multiple users or through local "Claude Code" sessions.
