Before you start
You need a Nefin account on the Professional or Business plan, with AI switched on for at least one company. An owner turns it on in Settings → Company. The connection is read-only until you turn on Allow changes when you connect, and every change it makes shows in the audit log under your name.
An app that isn’t listed can still work. Any app that speaks MCP over HTTP can use the server URL above, with OAuth sign-in or a personal token from Account → AI connectors.
