Overview

AI-generated overview

Remote cyon MCP server that lets an assistant read your cyon hostings and create subdomains, databases, certificates and publish sites.

What you can do
  • Read the hostings on your cyon account
  • Create subdomains, databases and HTTPS certificates
  • Publish a website to a hosting
  • Work with domains and deployment for sites built on cyon hosting
When to use it
Useful when you build or maintain websites on cyon hosting and want the assistant to inspect your hostings and set up subdomains, databases, certificates or deployments without leaving the chat.
Requirements
A remote endpoint at mcp.cyon.ch over streamable HTTP with OAuth login. You need a cyon account and must approve the connection in the browser at my.cyon, where you also choose which hostings the assistant may reach. No environment variables or headers are declared.
Before you install
The assistant can create subdomains, databases and certificates and publish sites on your hosting, so changes are made to live infrastructure. Access is limited to the hostings you select during OAuth approval; review that selection and the actions before confirming.

Installation

In SourceWeft

  1. Open cyon in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ch.cyon%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

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-pluginclaude plugin install cyon@cyon

Codex:

codex plugin marketplace add cyon/cyon-plugincodex plugin add cyon@cyoncodex 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.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
