Install Onyx

Install the local client, then connect to a host. Onyx provisions the remote server over SSH when needed.

Overview Install Shell Exec MCP

Quickstart

Homebrew installs and updates the local client. Connect with the same host syntax you already use.

Install

brew install shervin9/onyx/onyx --formula

Update

brew upgrade shervin9/onyx/onyx --formula

Connect

onyx user@host

Bootstrap model

On first connect, Onyx uses SSH to upload and start the matching remote server binary. Bootstrap also reads the remote server auth token used to authorize QUIC streams.

Normal path

onyx user@host handles bootstrap and token reading automatically.

No bootstrap

--no-bootstrap requires ONYX_AUTH_TOKEN.

Security

QUIC uses TOFU certificate pinning plus a per-server auth token.
