# ConnectOnion

A CLI harness that lets any agent that can run a shell command reach real services, such as Gmail, a persistent browser and messaging apps, without needing its own OAuth app or SDK per service.

ConnectOnion gives an AI agent a set of command-line tools for reaching outside systems, so it does not need a separate OAuth app, DNS records or a custom script for every service it wants to use. Each capability is a `co` subcommand the agent runs in its shell, including identity and authentication, a persistent browser that stays logged in after a manual sign-in and 2FA, Gmail, Outlook and calendar access, and chat channels such as SMS, Telegram and WhatsApp.

Because the agent only needs to know the `co` command itself, which documents its own subcommands and hints at what to run next, its actions stay legible as a list of shell commands rather than opaque API calls. Google and Microsoft credentials are stored only on the user's own computer, and shell, file-write and email actions pause for approval when a chat UI is attached. It installs with `pip install connectonion` and is licensed Apache-2.0.
