AWS Architecture Diagram
MCP Server
- Command:
uvx awslabs.aws-diagram-mcp-server@latest (stdio transport)
- Requires:
AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION (or AWS_PROFILE)
- Dependency: Requires
graphviz installed on the system (apt install graphviz or brew install graphviz)
Key Capabilities
- Auto-discovery: Scan AWS account and render infrastructure as a diagram
- Network topology: VPCs, subnets, route tables, IGW, NAT GW, TGW connections
- Service mapping: EC2, ELB, RDS, Lambda placed in their VPC/subnet context
- Multiple formats: PNG, SVG, PDF output
- Filtered views: Scope diagram to specific VPCs, services, or tags
Workflow: Network Architecture Diagram
When a user asks "draw our AWS network" or "show me the architecture":
- Generate diagram: Use diagram tool scoped to networking resources
- Include: VPCs, subnets (public/private), IGW, NAT GW, TGW, VPN, peering connections
- Label: CIDR blocks, subnet names, AZ placement
- Connections: Show routing paths — TGW attachments, peering links, VPN tunnels
- Output: PNG or SVG file for sharing in Slack or documentation
- Report: Architecture summary alongside the diagram
Workflow: VPC Detail Diagram
When focusing on a specific VPC:
- Scope to VPC: Filter diagram to one VPC by ID or tag
- Show subnets: Public, private, isolated — grouped by AZ
- Show route tables: Main and custom route tables with key routes
- Show gateways: IGW, NAT GW, VPC endpoints
- Show security: NACLs, security group relationships
- Output: Detailed VPC topology diagram
Workflow: Multi-Account Network Diagram
When documenting cross-account architecture:
- Hub-spoke topology: Show Transit Gateway as the hub
- VPC attachments: Each spoke VPC with its CIDR and purpose
- Route propagation: Show which routes propagate where
- VPN/DX: On-premises connections via VPN or Direct Connect
- Inspection VPC: Network Firewall placement if applicable
- Output: Enterprise network topology diagram
Integration with Other Skills
| Skill | How They Work Together |
|---|
aws-network-ops | Discover VPCs/TGWs first, then diagram them |
aws-cloud-monitoring | Add CloudWatch metrics annotations to diagram |
aws-cost-ops | Annotate diagram with cost per resource |
markmap-viz | Generate mindmap alternative for simpler overviews |
Diagram Scoping Tips
| Scope | When To Use |
|---|
| Full account | Initial architecture review or documentation |
| Single VPC | Troubleshooting or VPC-specific audit |
| TGW + attachments | Multi-VPC connectivity review |
| Subnet-level | Security audit or routing investigation |
| Tagged resources | Application-specific or team-specific views |
Important Rules
- Graphviz required — the MCP server generates Graphviz DOT files and renders them;
graphviz must be installed
- Large accounts may produce complex diagrams — scope with filters for clarity
- Region-specific — diagram shows resources in the configured AWS_REGION only
- Read-only — only discovers and renders, never modifies resources
- Record in GAIT — log diagram generation for audit trail
Environment Variables
AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION (or AWS_PROFILE)
