Construct Overview

Opinionated L2 constructs for Amazon Bedrock AgentCore.

AgentCore Gateway (MdaaAgentcoreGateway)

MdaaAgentcoreGateway wraps the L1 CfnGateway and enforces MDAA's gateway-resource compliance invariants. It creates no dependencies of its own — the execution role, KMS CMK, and interceptor Lambda functions are resolved by the caller (the bedrock-agentcore-gateway-l3-construct orchestration construct) and supplied here as ARNs / resolved configurations.

Security/Compliance

  • Enforce customer-managed KMS CMK encryption — kmsKeyArn is required; the gateway is never left on an AWS-managed key
  • Restrict inbound authorization to CUSTOM_JWT or AWS_IAM — NONE (unauthenticated) and AUTHENTICATE_ONLY (no per-caller authorization) are rejected

AgentCore Gateway Target (MdaaAgentcoreGatewayTarget)

MdaaAgentcoreGatewayTarget wraps the L1 CfnGatewayTarget and enforces MDAA's target-resource compliance invariants. It creates no dependencies of its own — the gateway is supplied by identifier, and the lambda:InvokeFunction grant on the gateway execution role plus the explicit CloudFormation dependency on the gateway are owned by the caller (the bedrock-agentcore-gateway-l3-construct orchestration construct, which registers targets alongside the gateway).

The targetConfiguration declares one tool source. The type surface covers all AWS target types (lambda, openApiSchema, smithyModel, mcpServer, apiGateway) so the configuration is stable as support is added; validation currently builds only lambda and rejects the others as not yet supported. A Lambda toolSchema is one of inlinePayload or s3.

Security/Compliance

  • Default and restrict the outbound credential provider to GATEWAY_IAM_ROLE — an unsupported type is rejected
