Enterprise Platform on Amazon Bedrock AgentCore for Assembling, Not Developing, AI Agents

The Amazon Bedrock AgentCore-based enterprise platform proposes a method of deploying by assembling validated components instead of developing agents from scratch each time. Engineers configure Context Boundary, Gateway, and Delegation via a web UI and register the completed agents as reusable Cards.

Context Boundary defines the agent's role and scope of responsibility, while Gateway bundles operational tools such as CloudWatch, EKS, and cross-account lookups, exposing them via the MCP (Model Context Protocol) interface. Complex tasks are delegated by the Supervisor agent to sub-domain agents.

The platform consists of the following four layers.

• Presentation Layer: CloudFront and Next.js 14 UI, private ALB connection via VPC Origin, Cognito JWT authentication
• Control Plane: FastAPI on ECS Fargate handling Card CRUD, AgentCore integration, session management, and observability queries
• Agent Runtime: Running Strands SDK containers on Bedrock AgentCore's managed runtime
• Tool Layer: Bundling Lambda functions based on boto3 and AWS CLI into a Gateway to provide MCP tools

Agent Cards can be tested in the Playground or reassembled in the Design screen. When the Deploy button is pressed, the Control Plane creates an AgentCore Runtime using the URI of a pre-built base image, and AgentCore pulls and runs the ECR image, eliminating the need for engineers to directly manage containers or servers.

Metadata and incidents are stored in DynamoDB, and reports are stored in S3. CloudWatch alarms trigger automated incident response via EventBridge. The entire infrastructure is codified into 8 Terraform modules, allowing approximately 70 resources to be created with a single terraform apply.

Currently, the Card Registry and some platform features are directly implemented, but they can later be replaced by AgentCore's managed Agent Registry to reduce operational burden. The core idea is transforming tools created by individuals into shared and reusable assets at the organizational level.
