How I Used Kiro + MCP to Document, Analyze, Improve and Visualize My AWS Linktree-Style Project
As an AWS Community Builder, I love experimenting with new developer workflows that combine automation, cloud architecture and AI tooling. This article describes how I used Kiro equipped with Model Context Protocol (MCP) servers to automatically analyze, document, diagram, audit and improve a real production project I run on AWS.
My Personal Project: A Fully Serverless "Linktree-Style" Website on AWS
Before diving into MCP, here’s the context.
I maintain a personal production project:
a Linktree-style website built entirely by me, deployed on AWS with:
- S3 (static hosting, private bucket)
- CloudFront (global delivery)
- OAC (Origin Access Control)
- CloudFront Functions (routing logic)
- Route 53 (DNS and ALIAS records)
- ACM Certificate (TLS)
- GitHub Actions CI/CD
- Terraform IaC (complete infrastructure automation)
This project has grown over time, and I wanted a faster — and smarter — way to:
- Understand and document the system
- Validate architecture decisions
- Receive AWS best-practice recommendations
- Generate diagrams using official AWS icons
- Improve Terraform (security, cost and performance)
- Inspect GitHub workflows and suggest enhancements
That’s when Kiro + MCP changed everything.
What Kiro + MCP Did for This Project
After installing five MCP servers, Kiro became a full cloud architecture assistant.
Here is exactly what it did:
1. Generated a complete Spec File
Kiro analyzed my GitHub repo, Terraform code, static files and folder structure.
Then it produced a clear, structured Spec File describing:
- System purpose
- AWS services used
- CI/CD workflow
- Deployment strategy
- Security posture
- Future improvements
This Spec became a “living blueprint” for the project.
2. Created a full AWS architecture diagram (Draw.io) by itself
Using the diagram MCP, Kiro generated a .drawio file with:
- Official AWS icons (mxgraph.aws4)
- S3, CloudFront, Route 53, IAM, OAC
- Data flows with arrow labels
- Component descriptions
- Legend and grouping
The diagram opens perfectly in app.diagrams.net.
3. Produced complete documentation using AWS official MCPs
Using:
awslabs.aws-documentation-mcp-serverawslabs.core-mcp-servermcp-server-fetchgithub MCPdiagram-ai MCP
Kiro:
- Looked up AWS best practices
- Compared my architecture to AWS recommendations
- Generated docs in clear, well-structured English
- Validated my CloudFront, S3 and Route 53 setup
- Suggested improvements using AWS Well-Architected
All with citations and references to AWS documentation pages.
4. Identified improvements and generated new Spec Files to implement them
Examples Kiro suggested (and generated code/specs for):
Security
- Add AWS WAF to CloudFront
- Enforce TLS 1.3
- Ensure S3 bucket has encryption + private access
- IAM improvements for GitHub OIDC
Logging
- Enable CloudFront logging
- Optimize TTLs
- Split long-cache and short-cache assets (I implemented this)
Performance
- Gzip/Brotli checks
- Image resizing recommendations
- Use CloudFront Functions instead of Lambda@Edge when possible
Kiro even generated Terraform snippets to apply each change.
