Implement custom authentication for tools integration using request Lambda interceptor in AgentCore Gateway

Summary of the Blog Post: Bridging Authentication Patterns with Amazon Bedrock AgentCore Gateway

The blog post discusses a solution for integrating legacy tools that require Basic Auth headers into an environment where modern authentication patterns like OAuth 2.0 are used, specifically in the context of Amazon Web Services (AWS) and Amazon Bedrock AgentCore Gateway.

Key Points:

1. Problem Statement:

   • Legacy tools often use Basic Auth headers, while newer systems prefer OAuth 2.0 or similar standards.
   • The challenge is to bridge this gap without modifying the legacy tool's API schema or the agent's implementation.

2. Solution Overview:

   • A request Lambda interceptor is introduced as an intermediary solution.
   • This interceptor validates JWT tokens and retrieves system credentials from AWS Secrets Manager to construct Basic Auth headers for downstream tools.

3. Implementation Details:

   • Step 1: Configure Request Interceptor in Gateway:
     • Set up a request Lambda interceptor that intercepts requests before they reach the agent.
     • The configuration includes specifying the ARN of the Lambda function and defining interception points (e.g., REQUEST).
