MasterGo Magic MCP

MasterGo Magic MCP is a standalone MCP (Model Context Protocol) service designed to connect MasterGo design tools with AI models. It enables AI models to directly retrieve DSL data from MasterGo design files.

Key Features

• Retrieves DSL data from MasterGo design files
• Runs directly with npx
• No external dependencies required, only Node.js environment needed

Usage

Obtaining MG_MCP_TOKEN

1. Visit https://mastergo.com
2. Enter personal settings
3. Click the Security Settings tab
4. Find the personal access token
5. Click to generate the token

Permission Requirements

Important: If the tool is connected but returns a "no permission" error, please check the following conditions:

1. Account Version Requirement:

   • Requires Team Edition or higher MasterGo account
   • Personal free edition does not support MCP tool access

2. File Location Requirement:

   • Design files must be placed in Team Projects
   • Files in draft box cannot be accessed via MCP tools

Command Line Options

npx @mastergo/magic-mcp --token=YOUR_TOKEN [--url=API_URL] [--rule=RULE_NAME] [--debug] [--no-rule]

Parameters:

• --token=YOUR_TOKEN (required): MasterGo API token for authentication
• --url=API_URL (optional): API base URL, defaults to http://localhost:3000
• --rule=RULE_NAME (optional): Add design rules to apply, can be used multiple times
• --debug (optional): Enable debug mode for detailed error information
• --no-rule (optional): Disable default rules

You can also use space-separated format for parameters:

npx @mastergo/magic-mcp --token YOUR_TOKEN --url API_URL --rule RULE_NAME --debug

Environment Variables

Alternatively, you can use environment variables instead of command line arguments:

• MG_MCP_TOKEN or MASTERGO_API_TOKEN: MasterGo API token
• API_BASE_URL: API base URL
• RULES: JSON array of rules (e.g., '["rule1", "rule2"]')

You can configure the MCP server using either command line arguments or environment variables:

Option 1: Using command line arguments

{
  "mcpServers": {
    "mastergo-magic-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@mastergo/magic-mcp",
        "--token=<MG_MCP_TOKEN>",
        "--url=https://mastergo.com"
      ],
      "env": {}
    }
  }
}

Option 2: Using environment variables

{
  "mcpServers": {
    "mastergo-magic-mcp": {
      "command": "npx",
      "args": ["-y", "@mastergo/magic-mcp"],
      "env": {
        "MG_MCP_TOKEN": "<YOUR_TOKEN>",
        "API_BASE_URL": "https://mastergo.com"
      }
    }
  }
}

• http-util.ts: Utility for handling HTTP requests to the MasterGo API
• types.d.ts: TypeScript type definitions for the project

src/tools

Contains implementations of MCP tools:

• base-tool.ts: Base class for all MCP tools
• get-dsl.ts: Tool for retrieving DSL (Domain Specific Language) data from MasterGo design files
• get-component-link.ts: Tool for retrieving component documentation from links
• get-meta.ts: Tool for retrieving metadata information
• get-component-workflow.ts: Tool providing structured component development workflow for Vue and React components, generating workflow files and component specifications

src/markdown

Contains markdown files with additional documentation:

• meta.md: Documentation about metadata structure and usage
• component-workflow.md: Component development workflow documentation guiding structured component development process

Local Development

1. Run yarn and yarn build to install dependencies and build the code
2. Find the absolute path of dist/index.js
3. Add local MCP configuration with your token

"mastergo-mcp-local": {
  "command": "node",
  "args": [
    "absolute/path/to/dist/index.js",
    "--token=mg_xxxxxx",
    "--url=https://mastergo.com",
    "--debug"
  ],
  "env": {}
},

1. Restart your editor to ensure the local MCP is enabled

After successful execution, you can debug based on the local running results. You can build your own MCP service based on your modifications.

We welcome your code contributions and look forward to building MasterGo's MCP service together.
