Cotlet works in the account through your Cloud Browser, a real Chrome where you sign in to Dentrix Ascend yourself; Cotlet does not store your password and you need no Dentrix Ascend API key. About the official Dentrix Ascend API: Dentrix Ascend has an API, but only for software vendors approved into the Henry Schein One API Exchange, not for a practice that wants to connect its own AI agent (checked 27 Oct 2026). Henry Schein One announced an MCP layer inside Dentrix Ascend on 28 Apr 2026: an Ask preview for questions in plain language, pre-built agents for select customers and a Build layer with no published date or developer docs.
