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

## Example Prompts
Once the MCP server is connected, you can use the following prompts in your AI chat:
**Extract SVG and preview in HTML:**
```
Extract SVG and preview in HTML: https://{domain}/file/{fileId}?layer_id={layerId}
```
**Restore a design to code:**
```
Restore design: https://{domain}/file/{fileId}?layer_id={layerId}
```
Replace `{domain}`, `{fileId}`, and `{layerId}` with your actual values. You can also use short links:
```
Restore design: https://{domain}/goto/{shortLink}
```
**Restore a design and save as an HTML file:**
```
Restore design, save as HTML file: https://{domain}/file/{fileId}?layer_id={layerId}
```
You can also use short links:
```
Restore design, save as HTML file: https://{domain}/goto/{shortLink}
```
## 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] [--proxy=PROXY_URL] [--format=FORMAT] [--header "Key: Value"] [--debug] [--no-rule] [--no-prefix]
```
#### 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
- `--proxy=PROXY_URL` (optional): HTTP/HTTPS proxy URL (e.g., `http://127.0.0.1:7890`), also supports `HTTPS_PROXY` / `HTTP_PROXY` environment variables
- `--header "Key: Value"` (optional): Custom HTTP request header, can be used multiple times. **Quote the value** when it contains spaces. Custom headers override the defaults — including `Content-Type` and the auth token — so match the default key exactly when overriding. Also settable via the `MG_EXTRA_HEADERS` environment variable as a JSON object (e.g. `MG_EXTRA_HEADERS='{"X-Custom":"val"}'`); CLI headers take precedence over env.
- `--format=FORMAT` (optional): Default output format for design-data tools — one of `json` (default), `yaml`, `tree`. An explicit per-call `format` tool parameter overrides this. Also settable via the `DEFAULT_FORMAT` environment variable.
- `--debug` (optional): Enable debug mode for detailed error information
- `--no-rule` (optional): Disable default rules
- `--no-prefix` (optional): Register tools without the `mcp__` name prefix (e.g. `getDsl` instead of `mcp__getDsl`). Some MCP clients (such as Grok Build) silently skip tools whose fully-qualified `server__tool` name contains more than one `__` separator — since the server is already prefixed, a `mcp__getDsl` tool name becomes `server__mcp__getDsl` and is dropped. Enable this flag for those clients. Also settable via the `MG_NO_PREFIX` environment variable (`1`/`true`/`yes`).
You can also use space-separated format for parameters:
```
npx @mastergo/magic-mcp --token YOUR_TOKEN --url API_URL --rule RULE_NAME --proxy PROXY_URL --format FORMAT --header "Key: Value" --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"]'`)
- `DEFAULT_FORMAT`: Default output format for design-data tools (`json` | `yaml` | `tree`); the `--format` argument and an explicit per-call `format` tool parameter take precedence.
- `MG_NO_PREFIX`: Set to `1`/`true`/`yes` to register tools without the `mcp__` name prefix (the `--no-prefix` argument takes priority).
- `HTTPS_PROXY` / `https_proxy` / `HTTP_PROXY` / `http_proxy`: HTTP(S) proxy URL (the `--proxy` argument takes priority)
### Tool Output Format
The design-data tools (`mcp__getDesignSections`, `mcp__getDsl`, `mcp__getDesignSvgs`, `mcp__getDesignTexts`, `mcp__extractSvg`, `mcp__getMeta`) accept an optional `format` parameter that controls how the payload is serialized. It defaults to `json`, or to the value set via `--format` / `DEFAULT_FORMAT` (see [Command Line Options](#command-line-options)).
| Value | Description |
| --- | --- |
| `json` | **Default.** Compact JSON — useful when piping output into tools that expect JSON. Byte-identical to the prior behavior. |
| `yaml` | Fewer tokens than JSON for typical designs (flat layouts with repeated values benefit most). |
| `tree` | Experimental compact format. Structural keys (`id`, `name`, `type`) are encoded positionally on each node line, and style values stay deduplicated in a `globalVars` block. Designs with heavy style reuse see the largest token savings. |
The format is chosen per tool call by the AI model. To influence it, mention the desired format in your prompt, for example:
```
Restore design, use tree format: https://{domain}/file/{fileId}?layer_id={layerId}
```
Notes:
- `tree` applies to all six tools' responses: `mcp__getDesignSections` (section list and per-section DSL), `mcp__getDsl`, `mcp__getDesignSvgs`, `mcp__getDesignTexts`, `mcp__extractSvg`, and `mcp__getMeta`. `mcp__getMeta` falls back to JSON under `tree` because its `rules` field is markdown (the tree layout would corrupt the markdown's headings/code blocks); other payloads render as tree. Truly unknown shapes also fall back to JSON — no data is ever mis-formatted.
- For `mcp__getDesignTexts`, `json` is recommended for maximum verbatim-text fidelity — though all formats round-trip without data loss.
- All formats round-trip without data loss. An invalid or omitted `format` value falls back to `json`.

### cursor Usage
Cursor Mcp usage guide reference: https://docs.cursor.com/context/model-context-protocol#using-mcp-tools-in-agent
You can configure the MCP server using either command line arguments or environment variables:
**Option 1: Using command line arguments**
```json
{
"mcpServers": {
"mastergo-magic-mcp": {
"command": "npx",
"args": [
"-y",
"@mastergo/magic-mcp",
"--token=<YOUR_TOKEN>",
"--url=https://mastergo.com"
],
"env": {}
}
}
}
```
**Option 2: Using environment variables**
```json
{
"mcpServers": {
"mastergo-magic-mcp": {
"command": "npx",
"args": ["-y", "@mastergo/magic-mcp"],
"env": {
"MG_MCP_TOKEN": "<YOUR_TOKEN>",
"API_BASE_URL": "https://mastergo.com"
}
}
}
}
```
**Option 3: Using SSE (Streamable HTTP)**
No local installation required. The MCP server runs remotely and is accessed via SSE:
```json
{
"mcpServers": {
"mastergo-magic-mcp": {
"type": "http",
"url": "https://mastergo.com/mcp/xf/sse",
"headers": {
"x-mg-useraccesstoken": "<YOUR_TOKEN>"
}
}
}
}
```
### cline Usage
**Option 1: Using command line arguments**
```json
{
"mcpServers": {
"@master/mastergo-magic-mcp": {
"command": "npx",
"args": [
"-y",
"@mastergo/magic-mcp",
"--token=<YOUR_TOKEN>",
"--url=https://mastergo.com"
],
"env": {}
}
}
}
```

}
}
}
```
### Open Code Usage
Open Code uses a `mcp` configuration block with `type: "local"` and `command` array:
```json
{
"mcp": {
"mastergo-magic-mcp": {
"type": "local",
"command": [
"npx",
"-y",
"@mastergo/magic-mcp",
"--token=<YOUR_TOKEN>",
"--url=https://mastergo.com"
],
"environment": {
"NPM_CONFIG_REGISTRY": "https://registry.npmjs.org/"
},
"enabled": true
}
}
}
```

## 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
```json
"mastergo-mcp-local": {
"command": "node",
"args": [
"absolute/path/to/dist/index.js",
"--token=mg_xxxxxx",
"--url=https://mastergo.com",
"--debug"
],
"env": {}
},
```
4. 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.
