Authentication and permissions

OAuth 2.1 with PKCE, per-group permission scopes and access revocation for the Sidemex MCP server.

Read as Markdown

The Sidemex MCP server is an OAuth resource server. Sign-in uses the same account system as the sidemex.net dashboard.

  1. The MCP client discovers configuration at https://mcp.sidemex.net/.well-known/oauth-protected-resource/mcp.
  2. It opens Sidemex sign-in with PKCE (S256).
  3. You choose the permissions.
  4. The client receives a short-lived access token valid only for the Sidemex MCP server.
Scope Allows
domains:read View your domains, quote, create payment links, check orders
dns:write Create, change and delete DNS records on your domains
email:write View, create and delete mailboxes; generate password-change links
balance:read View balance and history

An assistant can only do what the approved scopes allow, and only on domains in your account.

From your sidemex.net dashboard you can see which applications have access and revoke it at any time. Every action an assistant takes is recorded in your activity history.
