# Commands

Use `mcpstack <command>` for interactive harness selection or `--harness codex` or `--harness claude` for unattended runs. Namespaced `mcpstack <harness> <command>` forms remain available. Only `import` accepts multiple harnesses. `--config <PATH>` selects a configuration for one harness.

`--non-interactive` disables prompts; `-y` approves changes. Permissions always require `--include-permissions`.
