Tips

Grok CLI is a single Rust binary; first launch opens a browser to authorize. In browser-less/CI environments, the `XAI_API_KEY` env var runs headless tasks.
`grok inspect` lists the config, skills, hooks, and MCP servers Grok discovered in the cwd — handy when debugging why your config is not picked up.
Custom models live under `[model.my-model]` in `~/.grok/config.toml`; select them in the TUI with `/model` or via `-m`.

FAQ

Is the Grok CLI the same as the community grok-cli (npm) package?

No. This sheet covers xAI official Grok Build CLI (command `grok`, distributed via the x.ai/cli install script). The npm `grok-cli` (e.g. airplne/grok-cli) is a third-party community implementation with different commands and config — do not mix them.

How do I use Grok CLI without a graphical browser?

Set the `XAI_API_KEY` env var and run `grok -p "..."` for headless tasks — no browser auth needed. Only the interactive TUI requires the first browser OAuth.
