How do I obtain a MasterGo API Token?

Log in to MasterGo, go to the [Developer Center](https://mastergo.com/developers), and create a new application or generate a personal access token under your account settings.

Can I read specific layer information through this server?

Yes. Use the `list_nodes` tool with the file key and optional node IDs. This allows your agent to retrieve detailed data about frames, layers, and their properties.

What is a 'fileKey' in MasterGo?

The `fileKey` is the unique identifier found in the URL of your MasterGo design file. It typically appears after `/file/` in the browser address bar.
