Terraform MCP Server Explained: Setup and Use Cases

The Terraform MCP server connects AI agents to live Terraform Registry data, enabling accurate, version-specific provider and module documentation instead of relying on stale training data. It ships with 44 tools covering registry queries and HCP Terraform/Terraform Enterprise operations like workspace creation and run management. The post walks through local setup using Docker with VS Code and GitHub Copilot, demonstrates two primary use cases (querying the public registry and managing HCP Terraform workspaces), and covers security best practices including least-privilege tokens, local hosting, confirmation prompts for action-tools, and disabling destructive operations via ENABLE_TF_OPERATIONS.
