cyon plugin for Claude Code and Codex

Skills that know what cyon hosting runs, and the connection to the cyon MCP server, through which the assistant reads your hostings and creates subdomains, databases and certificates and publishes a site.

Installing

Claude Code:

claude plugin marketplace add cyon/cyon-plugin
claude plugin install cyon@cyon

Codex:

codex plugin marketplace add cyon/cyon-plugin
codex plugin add cyon@cyon
codex mcp login cyon

At the first tool call, or at codex mcp login, your browser opens my.cyon. Log in and approve the connection, and the tools appear. You choose there which hostings the assistant may reach.

Contents

The skills are in plugin/skills/, what changed in each version is in plugin/CHANGELOG.md.
