Auth

Manage providers, MCP servers, and gateway tokens with the interactive auth TUI.

crabtalk auth is an interactive terminal UI for managing your configuration. Three tabs, keyboard-driven, saves to crab.toml.

Tabs

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.

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

Manage tokens for gateway services like Telegram. Set or clear tokens without editing config files directly.

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