Turn on the Duaer MCP server

In Duaer, expose the instance as an MCP server so outside clients operate digital organizations with permission. Turn access on in the instance first.

Turn it on on the instance first

Open Duaer’s MCP access settings.
Enable instance-level MCP.
Note the URL and auth material the client needs.

Until it is on, an outside client has no server to reach. Cloud onboarding for new users also points docs here. How the client fills in the URL and auth is connect to MCP. On cloud, the entry may also be labelled MCP access.

Questions

What can an outside client do after the Duaer MCP server is on?

An MCP-capable client can, with permission, create or run digital organizations. You turn access on in the instance MCP settings. How the client fills in the URL is on the connect page.

How is this Duaer page different from the connect-an-MCP-client page?

This page turns MCP access on inside Duaer. Connecting a client, authentication, and the tool list are on the connect page. Both sides must be set before the client can reach the instance.
