CactusHelp Center custom domains New
Sep 19–21, 2026 · Help Center and agents
Give your Help Center a custom domain so customers can open it at an address your team owns.
Set a custom address for your Help Center
Point a custom hostname to Cactus with a CNAME record, then follow its verification and certificate status in Connect. Cactus serves the Help Center from that address.
AI clients see tools their access allows
The AI clients page gives you a user-level install command and hands sign-in back to you. Cactus offers each caller only the MCP tools their access permits, and outside clients receive readable answers with links to cited help pages.
Add notes and draft replies in the Inbox
In an Inbox conversation, add an internal note, ask Cactus, or draft a customer reply in the composer. A draft stays unsent until you choose to send it, and replies render as formatted prose in Messenger.
First AI client searches run their queries
Your first code search runs its queries even if an AI client sends an unknown page cursor. Cactus asks you to search again only when a cursor it issued is no longer available.
Inspect a Help Center page's source
Use the Published and Source switch above a Help Center page to inspect its live sections, supporting code, unanswered questions and applied Rules. Source view is available to your team in the app, not to public Help Center visitors.
