Terraform MCP Server

🚀 Terraform MCP Server by Binadox

The Terraform MCP Server, developed by Binadox, is designed to automatically validate, secure, and estimate cloud costs for Terraform configurations. It can integrate with any Model Context Protocol (MCP) client, such as Claude Desktop or other MCP-compatible AI assistants.

🚀 Quick Start

The Binadox Terraform MCP Server is an MCP (Model Context Protocol) server. It serves as a bridge between your AI assistant and Terraform, helping large language models (LLMs) safely generate Terraform infrastructure code. Before deployment, it conducts built - in cost estimation and security checks, ensuring the Terraform configuration is more complete, secure, and cost - aware.

✨ Features

• Code validation & completion: Processes Terraform snippets and fills in missing parts (providers, versions, variables) to create a runnable configuration.
• Security analysis: Detects common misconfigurations and insecure defaults (open ports, missing encryption, etc.) in the generated code.
• Cost estimation: Computes a monthly cloud cost breakdown for the proposed resources using real pricing data.
• File organization: Organizes output into logical Terraform files/modules (e.g., groups resources into modules, adds terraform.tfvars if needed).
• Easy integration: Works with any MCP - compatible client (tested with Claude Desktop) for seamless use in your AI - driven workflow.

📦 Installation

To install binadox - terraform - mcp, follow these steps:

1. Clone and build:

git clone https://github.com/binadox/binadox-terraform-mcp
cd binadox-terraform-mcp
go build -o terraform-mcp-server *.go

2. Configure your MCP client (example: Claude Desktop):

# Add to Claude Desktop config
# macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
# Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "terraform": {
      "command": "/path/to/terraform-mcp-server",
      "env": {
        "TERRAFORM_ANALYSIS_URL": "https://app.binadox.com/api/1/organizations/pricing/terraform/mcp",
        "TERRAFORM_ANALYSIS_TOKEN": "your-token"
      }
    }
  }
}

3. Restart your MCP client to apply the configuration.

💻 Usage Examples

Basic Usage

No additional CLI commands are required. Once installed and configured, the server operates behind the scenes to:

• Validate and complete Terraform code via prepare_terraform.
• Analyze for misconfigurations via analyze_terraform.
• Estimate cloud costs via calculate_cost.

All output files are written to /tmp/terraform/<timestamp> and zipped if needed.

Advanced Usage

Cost Overrun Prevention

User: Generate terraform for a simple demo environment

Cost Analysis: $1,847/month
- m5.2xlarge instances
- Multi-AZ RDS
- NAT Gateways in 3 AZs

Security Misconfiguration Detection

User: Create an RDS database with a security group

Security Analysis:
- 0.0.0.0/0 open access
- No encryption at rest
- 1-day backup retention

Completing Incomplete Configurations

User: Add resource "aws_s3_bucket" "data" { bucket = "my-data" }

Without MCP: Fails – no provider block  
With MCP: Adds provider, variables, and metadata – configuration runs
