Terraform MCP Server

The Terraform MCP Server is a Model Context Protocol (MCP) server that provides seamless integration with Terraform Registry APIs, enabling advanced automation and interaction capabilities for Infrastructure as Code (IaC) development.

Features

• Dual Transport Support: Both Stdio and StreamableHTTP transports with configurable endpoints
• Terraform Registry Integration: Direct integration with public Terraform Registry APIs for providers, modules, and policies
• HCP Terraform & Terraform Enterprise Support: Full workspace management, organization/project listing, and private registry access
• Workspace Operations: Create, update, delete workspaces with support for variables, tags, and run management
• OTel metrics for monitoring tool usage: Track tool-call volume, latency and failures in Streamable HTTP mode

Security Note: Depending on the query, the MCP server may expose certain Terraform data to the MCP client and LLM. Do not use with untrusted MCP clients or LLMs.

Prerequisites

1. Docker installed and running (for containerized use)
2. An AI assistant that supports the Model Context Protocol (MCP)

Configurable via environment variables for HCP Terraform/Terraform Enterprise address, API token, transport mode (stdio or streamable-http), logging, and CORS settings.
