}Frequently asked questions
What is the Terraform MCP server?
It is a Model Context Protocol (MCP) server — a small piece of software that gives AI assistants like Claude a secure, governed connection to Terraform. Access Terraform Registry documentation, modules, and provider schemas. Generate accurate infrastructure-as-code configurations.
Is there an official Terraform MCP server?
Yes. The Terraform MCP server is an official integration, maintained by the vendor or the Model Context Protocol project, which makes it the safest default for business use. It is maintained by HashiCorp.
Is the Terraform MCP server hosted, or do I run it myself?
It runs locally. Your AI client starts it on your own machine with docker, and it talks to the client over standard input and output rather than the network.
Do I need an API key for the Terraform MCP server?
No. It runs on your machine with your own permissions, so there is no key to create.
What can an AI assistant actually do with Terraform?
Through this server an assistant can work with registry, providers, modules, iac generation — reading from and acting on Terraform directly instead of you copy-pasting between windows. What you allow it to do is controlled by the permissions you grant.
How do I set this up for my business?
The setup section above has copy-paste config for Claude Code, Claude Desktop, Cursor and VS Code. If you want it rolled out across a team with permissions, governance and support handled, that is what Crox's Build engagement covers.

Want this connected to your business — with governance handled?
Crox maps your processes, connects AI to the tools you already use, and keeps it working as models change. Start with a readiness assessment or talk to us about a build.
