# Auth

Manage providers and MCP servers with the interactive auth TUI.

`crabtalk config` is an interactive terminal UI for managing your configuration. Two tabs, keyboard-driven, saves to `config.toml`.

```
crabtalk config
```

## Tabs

### Providers

Add and edit LLM providers. Each provider has an API key, optional base URL, API standard, and a list of models. Set any model as the active default.

Provider presets: Anthropic, OpenAI, Google, Ollama, Azure, or custom endpoint.

### MCPs

Add and edit MCP server configurations. Set the command, arguments, and environment variables for each server.

## Alternative

You can always edit `~/.crabtalk/config.toml` directly. The config TUI reads and writes the same file.
