WHAT IT DOES

What run_terraform_command does on Azure Terraform MCP Server

AI agents invoke run_terraform_command to trigger actions in Azure Terraform MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
