See setup guidance ↓Original source ↗ SOURCE REVIEW Reviewed 2026-09-21 Evidence 4 linked sources Publisher AWS Labs Licence Apache-2.0 ↗ Revision 2773b69a20d1 Read what was—and wasn’t—checked ↓ “Get started with this MCP server for creating and troubleshooting AWS infrastructure as code.” AWS Labs · upstream description ↗ Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - Combines template validation and compliance checks with source documentation for the same infrastructure workflow. - The inspected tool definitions distinguish local template checks from account-backed deployment troubleshooting. ### A good fit for - Checking a CloudFormation template and diagnosing a failed stack before attempting another deployment. ### Weigh up before choosing - Validation and compliance results do not certify a template or deployment as safe. - Live stack troubleshooting needs AWS credentials and access to the relevant CloudFormation/CloudTrail information. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - src/aws-iac-mcp-server/README.md (installation, capability and permission sections) - src/aws-iac-mcp-server/pyproject.toml - src/aws-iac-mcp-server/awslabs/aws_iac_mcp_server/server.py - LICENSE ### Our findings - The server registers validation, compliance, troubleshooting and documentation tools; a resource deployment/apply tool was not established. - The current package is awslabs.aws-iac-mcp-server; obsolete CDK/Cloud Control entries should not be substituted. ### Not established by this review - Server startup, authentication and tool execution were not tested. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Connect a server deliberately. Upstream setup instructions ↗ DOCUMENTED COMMAND uvx awslabs.aws-iac-mcp-server@latest Copy command ↗ Copying does not execute this command. It may retrieve a newer version than the reviewed source. - Add the documented stdio configuration to the client. - Set the intended AWS profile when using live-account troubleshooting; provide template text for validation tools. ### Before you start - uv/Python; AWS credentials for tools that inspect account resources. ### Compatibility An MCP client supporting stdio. · uv/Python; AWS credentials for tools that inspect account resources. ### Implementation Python ### Transports stdio ### Infrastructure validation / Configured credentials or local access - Reads supplied templates, AWS documentation and authorized deployment diagnostic data. ### Cost model Local execution and any AWS API or underlying service usage apply. 04 / FOLLOW THE EVIDENCE ## The source trail. Our notes are separate from the original resource.
