Quick reference for install, interactive shell, resumable exec, and local MCP.

Install Shell Exec MCP

Overview

Onyx is a resilient remote shell, a resumable remote exec layer, and a local MCP backend for agents. It bootstraps over SSH, then uses QUIC with TOFU certificate pinning and a per-server auth token.

Install

Install the local client, update it, and connect to a host.
