3. Install Terraform CLI for workflow execution
4. Install Checkov for security scanning

Installation

Here are some ways you can work with MCP across AWS, and we'll be adding support to more products including Amazon Q Developer CLI soon: (e.g. for Amazon Q Developer CLI MCP, ~/.aws/amazonq/mcp.json):

{
  "mcpServers": {
    "awslabs.terraform-mcp-server": {
      "command": "uvx",
      "args": ["awslabs.terraform-mcp-server@latest"],
      "env": {
        "FASTMCP_LOG_LEVEL": "ERROR"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Security Considerations

When using this MCP server, you should consider:

• Following the structured development workflow that integrates validation and security scanning
• Reviewing all Checkov warnings and errors manually
• Fixing security issues rather than ignoring them whenever possible
• Documenting clear justifications for any necessary exceptions
• Using the RunCheckovScan tool regularly to verify security compliance
• Preferring the AWSCC provider for its consistent API behavior and better security defaults

Before applying Terraform changes to production environments, you should conduct your own independent assessment to ensure that your infrastructure would comply with your own specific security and quality control practices and standards, as well as the local laws, rules, and regulations that govern you and your content.
