What is the 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.
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.
- Version Control — Check the version history of design files to track changes and milestones.
How it works
- Subscribe to this server
- Enter your MasterGo API Token (X-MG-Authentication)
- Start managing your design workflow through Claude, Cursor, or any MCP-compatible client
Who is this for?
- UI/UX Designers — automate design asset organization and manage project files through natural language.
- Product Managers — track design progress and monitor comments across multiple projects via a unified AI interface.
- Design Ops — oversee design systems and style libraries across your organization without manual overhead.
- Frontend Developers — retrieve design node details and style information directly from your AI-powered development workspace.

Frequently asked questions
How do I obtain a MasterGo API Token?
Log in to MasterGo, go to the Developer Center, 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.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your MasterGo MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
