Bedrock Agent MCP CDK

Example Use Cases

• 1

  Execute custom MCP action groups from Amazon Bedrock using serverless Lambda functions inside a VPC.

• 2

  Integrate third-party MCP servers (Node.js STDIO-based) and automatically generate OpenAPI schemas for Bedrock action groups.

• 3

  Secure network isolation (private subnets, NAT, and VPC endpoints) when calling external MCP services from Lambda.

Description

This repository provides CDK stacks, Lambda handlers, and configuration to run Bedrock Agents that call out to MCP servers via Lambda action groups. It automates VPC setup (public/private subnets, NAT, endpoints), generates OpenAPI schemas for MCP integration, and supports bundling Node.js MCP servers for Lambda STDIO-based execution. It is a proof-of-concept focused on secure, serverless integration and local MCP packaging, with limitations around Node.js/STDIO-only MCP servers.
