Features

• Initialize Terraform working directories
• Generate and show execution plans
• Apply changes to infrastructure
• Destroy infrastructure
• Validate Terraform configurations
• Show current state or saved plans
• Manage Terraform workspaces

Prerequisites

• Python 3.8 or higher
• Terraform 1.5.7 or higher
• Docker and Docker Compose (optional)

Usage

Local Usage

1. Start the MCP server:

   python main.py
   

2. Use the MCP CLI to interact with the server:

   mcp terraform_init --working-dir ./terraform
   mcp terraform_plan --working-dir ./terraform
   mcp terraform_apply --working-dir ./terraform --auto-approve
   

Docker Usage

1. Start the MCP server:

   docker-compose up -d
   

2. Use the MCP CLI to interact with the server:

   mcp terraform_init --working-dir ./terraform
   mcp terraform_plan --working-dir ./terraform
   mcp terraform_apply --working-dir ./terraform --auto-approve
   

Example Terraform Configuration

The repository includes an example Terraform configuration that creates an EC2 instance in AWS:

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }
}

provider "aws" {
  region = var.region
}

resource "aws_instance" "example" {
  ami           = var.ami_id
  instance_type = var.instance_type

  tags = {
    Name = var.instance_name
  }
}

Available Tools

• terraform_init: Initialize a Terraform working directory
• terraform_plan: Generate and show an execution plan for Terraform
• terraform_apply: Apply the changes required to reach the desired state
• terraform_destroy: Destroy the infrastructure managed by Terraform
• terraform_validate: Validate the syntax and internal consistency of Terraform files
• terraform_show: Show the current state or a saved plan
• terraform_workspace_list: List Terraform workspaces
• terraform_workspace_select: Select a Terraform workspace

Example Usage

Here's an example of how to use the MCP server with an AI agent:

1. Start the MCP server:

   python main.py
   

2. Connect to the server using an MCP client:

   mcp connect http://localhost:8000
   

3. The AI agent can now help you with Terraform operations. For example:

   • Initialize a Terraform working directory
   • Generate and review execution plans
   • Apply changes to infrastructure
   • Destroy infrastructure resources
   • Validate Terraform configurations
