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.

About MasterGo MCP Server

Empower your AI agent to orchestrate your design workflow with MasterGo, the leading professional design tool for high-performance team collaboration. By connecting MasterGo to your agent, you transform complex design file navigation and project coordination into a natural conversation. Your agent can instantly list your files, retrieve design nodes (frames and layers), audit style libraries, and even browse version history without you ever needing to navigate the complex design workspace. Whether you are managing a large-scale design system or a specific UI project, your agent acts as a real-time design assistant, keeping your assets organized and your team aligned.

LlamaIndex agents combine MasterGo tool responses with indexed documents for comprehensive, grounded answers. Connect 10 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.

What you can do

File Orchestration — List all accessible design files and projects across your MasterGo workspace.
Node Management — Retrieve granular design nodes and layers to understand your UI structure instantly.
Collaboration Monitoring — Browse file comments and organization members to stay informed about team updates.
Style Auditing — List defined design styles, including colors and typography, across your files.
