Overview

What is Terraform MCP Server?

The Terraform MCP Server is a Model Context Protocol server that integrates with Terraform Registry APIs, HCP Terraform, and Terraform Enterprise. It enables AI assistants to manage Infrastructure as Code workflows, including workspace operations, provider/module lookups, and run management.

How to use Terraform MCP Server?

Run the server as a Docker container configured via environment variables. Connect it to an MCP-compatible assistant (VS Code, Cursor, Claude Desktop, etc.). Use the terraform-mcp-server stdio or terraform-mcp-server streamable-http command, or the equivalent Docker command, depending on your chosen transport mode. Set required environment variables like TFE_TOKEN, TFE_ADDRESS, and optionally TRANSPORT_MODE.

Key features of Terraform MCP Server

  • Dual transport: Stdio and StreamableHTTP
  • Terraform Registry integration for providers, modules, policies
  • HCP Terraform and Terraform Enterprise workspace management
  • Workspace CRUD with variables, tags, and run management
  • OpenTelemetry metrics for tool usage monitoring
  • Security and access controls (rate limiting, organization allowlists, TLS)

Use cases of Terraform MCP Server

  • Manage Terraform workspaces (create, update, delete) via chat
  • Query the Terraform Registry for provider and module versions
  • Automate infrastructure deployment with AI assistants
  • Audit workspace configurations and variables across organizations
  • Integrate IaC workflows directly into IDE agent mode (VS Code, Cursor)
