AWS Terraform MCP Server

How to setup AWS's Terraform MCP Server

Overview

AWS has open-sourced an MCP server specifically for using Terraform on AWS
It includes things like best practices, security scanning (checkov), documentation, and more
While AI is capable of writing Terraform, this provides it with more prescriptive and up-to-date guidance

Installation

Always review the source code for MCP servers to avoid running malicious code or commands.

Pre-Requisites

The following are required before the server will run

brew install uv terraform checkov
uv python install 3.10

MCP Setup

First, install the VS Code extension for the MCP server

Then run the installation command below to add the MCP server to your ~/.claude.json configuration
- --scope
  - setting to user will enable us to the MCP server anytime otherwise
  - setting to project will only use the MCP server within a project directory e.g., my-project-folder/project-code

Alternatively, you can copy/paste this into your ~/.cluade.json file for the same effect but the previous CLI command is recommended to avoid issues

MCP Health Checks

Check to ensure the MCP server is running

MCP Configuration

The GitHub repo for this particular AWS Terraform MCP server can be found here so be sure to review all the code it can run
Additionally, the MCP code gets cached locally and since we installed this with uv we can find the data in these paths

The * will be unique to your environment
