# cloudposse/atmos

Atmos is the open-source runtime for infrastructure — it builds, authenticates, and ships Terraform, OpenTofu, Kubernetes, Helm, and containers the same way on your laptop, in CI, and with AI agents.

## What it is
Atmos is an open-source CLI runtime for infrastructure that orchestrates Terraform, OpenTofu, Kubernetes, Helm, and containers through declarative YAML stack configuration, with built-in auth, secrets, vendoring, toolchain management, and CI support. It also exposes itself to AI agents via an MCP server and portable Agent Skills, letting assistants like Claude Code or Cursor operate infrastructure directly.

## Use cases
- manage terraform environments without copy-pasting code
- configure terraform components with yaml stacks
- run the same infrastructure commands locally and in ci
- manage cli tool versions for terraform and kubectl
- let ai agents operate terraform infrastructure via mcp
- dry multi-environment infrastructure configuration
- authenticate once for aws gcp and azure infrastructure workflows

## When to choose
- you manage many terraform environments and want DRY, inheritable configuration instead of duplicated root modules
- you want one tool to handle auth, secrets, tool versions, vendoring, and CI for Terraform/Helm/Kubernetes workflows
- your team wants AI agents (Claude Code, Cursor, Copilot) to safely drive infrastructure through MCP and agent skills
- you want consistent infrastructure commands across laptops, CI pipelines, and agent harnesses

## When to avoid
- you have a single small Terraform project where plain Terraform and a few scripts suffice
- you are not using Terraform/OpenTofu, Helm, or Kubernetes and don't need infrastructure orchestration
- you prefer bespoke wrapper scripts or tools like Terragrunt and don't want to learn Atmos's stacks/components model
- you need a GUI or fully managed SaaS rather than a CLI-driven workflow
