Configure API Server

The MCP Server communicates with StarUML's API Server using the HTTP protocol. You can disable the API Server or change the communication port.

If you want to configure API server, you can edit settings.json at the user configuration path:

• /Users/<user>/Library/Application Support/StarUML for Mac OS.

• C:\Users\<user>\AppData\Roaming\StarUML for Windows.

• ~/.config/StarUML for Linux.

To control whether the API Server runs, modify the apiServer field. To change the API Server port number, edit the apiServerPort field as below. Default port number is 58321.

{
  ...
  "apiServer": true,
  "apiServerPort": 58321
}
