FAQ from Terraform Registry MCP Server
What tools does the server provide?
It offers core registry tools (e.g., providerDetails, resourceUsage, moduleSearch) and Terraform Cloud tools (e.g., listOrganizations, createRun, lockWorkspace). A full tool list is available in the README.
Does it require authentication?
Public Terraform Registry tools do not need authentication. Terraform Cloud tools require a Terraform Cloud API token set via the TFC_TOKEN environment variable.
Is there a known issue with prompts?
Yes – the getPrompt method may cause server crashes. It is recommended to use listPrompts to see available prompts but avoid direct getPrompt calls until the issue is resolved.
What transport does the server use?
It uses stdio transport for MCP communication.
How can I configure the server?
Via environment variables: TERRAFORM_REGISTRY_URL, DEFAULT_PROVIDER_NAMESPACE, LOG_LEVEL, REQUEST_TIMEOUT_MS, RATE_LIMIT_ENABLED, RATE_LIMIT_REQUESTS, RATE_LIMIT_WINDOW_MS, and TFC_TOKEN. Defaults are documented in the README.
