AWS CDK MCP Server

Features

CDK General Guidance

• Prescriptive patterns with AWS Solutions Constructs and GenAI CDK libraries

• Structured decision flow for choosing appropriate implementation approaches

• Security automation through CDK Nag integration and Lambda Powertools

CDK Nag Integration

• Work with CDK Nag rules for security and compliance

• Explain specific CDK Nag rules with AWS Well-Architected guidance

• Check if CDK code contains Nag suppressions that require human review

AWS Solutions Constructs

• Search and discover AWS Solutions Constructs patterns

• Find recommended patterns for common architecture needs

• Get detailed documentation on Solutions Constructs

Generative AI CDK Constructs

• Search for GenAI CDK constructs by name or type

• Discover specialized constructs for AI/ML workloads

• Get implementation guidance for generative AI applications

Lambda Layer Documentation Provider

• Access comprehensive documentation for AWS Lambda layers

• Get code examples for generic Lambda layers and Python-specific layers

• Retrieve directory structure information and implementation best practices

• Seamless integration with AWS Documentation MCP Server for detailed documentation

Amazon Bedrock Agent Schema Generation

• Use this tool when creating Bedrock Agents with Action Groups that use Lambda functions

• Streamline the creation of Bedrock Agent schemas

• Convert code files to compatible OpenAPI specifications

Developer Notes

• Requirements: Your Lambda function must use BedrockAgentResolver from AWS Lambda Powertools

• Lambda Dependencies: If schema generation fails, a fallback script will be generated. If you see error messages about missing dependencies, install them and then run the script again.

• Integration: Use the generated schema with bedrock.ApiSchema.fromLocalAsset() in your CDK code

CDK Implementation Workflow

Available MCP Tools

• CDKGeneralGuidance: Get prescriptive advice for building AWS applications with CDK

• GetAwsSolutionsConstructPattern: Find vetted architecture patterns combining AWS services

• SearchGenAICDKConstructs: Discover GenAI CDK constructs by name or features

• GenerateBedrockAgentSchema: Create OpenAPI schemas for Bedrock Agent action groups

• LambdaLayerDocumentationProvider: Access documentation for Lambda layers implementation

• ExplainCDKNagRule: Get detailed guidance on CDK Nag security rules

• CheckCDKNagSuppressions: Validate CDK Nag suppressions in your code

Available MCP Resources

• CDK Nag Rules: Access rule packs via cdk-nag://rules/{rule_pack}

• AWS Solutions Constructs: Access patterns via aws-solutions-constructs://{pattern_name}

• GenAI CDK Constructs: Access documentation via genai-cdk-constructs://{construct_type}/{construct_name}

• Lambda Powertools: Get guidance on Lambda Powertools via lambda-powertools://{topic}

Prerequisites

1. Install uv from Astral or the GitHub README

2. Install Python using uv python install 3.10

3. Install AWS CDK CLI using npm install -g aws-cdk (Note: The MCP server itself doesn't use the CDK CLI directly, but it guides users through CDK application development that requires the CLI)

Installation

Security Considerations

• Reviewing all CDK Nag warnings and errors manually

• Fixing security issues rather than suppressing them whenever possible

• Documenting clear justifications for any necessary suppressions

• Using the CheckCDKNagSuppressions tool to verify no unauthorized suppressions exist
