About Terraform MCP

HashiCorp's official Terraform MCP server lets AI assistants search the Terraform Registry, read provider and module documentation, and reason about infrastructure-as-code without hallucinating resource arguments. It resolves provider schemas on demand, which dramatically improves the accuracy of generated Terraform configuration. Deployable locally or in a remote environment for team use. Once infrastructure is provisioned, the Kubernetes MCP setup helps an agent inspect workloads, and if you deploy to Microsoft's cloud you can connect Azure to Claude directly.
