MCP server for generating, validating, and deploying AWS CDK — delegates to AWS MCP servers

cdk-agent-mcp-server

MCP server that generates, validates, and deploys AWS CDK infrastructure from natural language.

Delegates to AWS MCP servers for validation, documentation, and pricing — no duplicate tooling.

User/Agent answers (or accepts defaults)

Prerequisites

• Python 3.10+, Node.js 18+ (for cdk synth/deploy), uv installed
• AWS CLI configured, Bedrock Claude Sonnet 4 enabled

Install

{
  "mcpServers": {
    "ict-mcp-server": {
      "command": "uvx",
      "args": ["ict-mcp-server"],
      "env": { "AWS_REGION": "us-east-1" }
    }
  }
}

Works with Kiro (~/.kiro/settings/mcp.json), Cursor (.cursor/mcp.json), Claude Code (claude mcp add), Amazon Quick Desktop (Settings → Capabilities → MCP).

Agent

Task	Delegates To	What It Does
clarify_requirements	Bedrock + Knowledge MCP	NL → structured clarifying questions with defaults
full_pipeline	All below	End-to-end: describe → clarify → plan → confirm → diagram → CDK → validate → costs
design_architecture	IaC MCP search_cdk_documentation	NL + requirements → architecture plan JSON
confirm_plan	Bedrock	Plan → human-readable summary for approval
generate_cdk_stack	IaC MCP search_cdk_documentation + search_cdk_samples_and_constructs	Plan → CDK TypeScript
validate_and_repair	cdk synth + IaC MCP validate_cloudformation_template + check_cloudformation_template_compliance	Validate + auto-repair loop
estimate_cost	Pricing MCP get_pricing + generate_cost_report	Real AWS pricing data
lookup_cdk_construct	IaC MCP search_cdk_documentation + search_cdk_samples_and_constructs + cdk_best_practices	CDK docs + samples + best practices
deploy_stack	cdk deploy	Real deployment (requires approved=true)
destroy_stack	CloudFormation DeleteStack	Delete stack (requires approved=true)
troubleshoot_deployment	IaC MCP troubleshoot_cloudformation_deployment	Root cause analysis for failed deploys
generate_diagram	Local	Architecture plan → Mermaid diagram

What We Don't Reimplement

Capability	Provided By
cfn-lint (template validation)	AWS IaC MCP Server
cfn-guard (compliance checking)	AWS IaC MCP Server
CDK documentation search	AWS IaC MCP Server
CDK code samples	AWS IaC MCP Server
CDK best practices	AWS IaC MCP Server
Deployment troubleshooting	AWS IaC MCP Server
AWS service pricing	AWS Pricing MCP Server
Cost report generation	AWS Pricing MCP Server

Our server only implements: architecture planning (Bedrock), CDK code generation (Bedrock), Mermaid diagrams (local), cdk synth/deploy (subprocess), and the orchestration glue.
