MasterGo Canvas MCP for DeepSeek Harness / MasterGo 画布插件

[zhourui01]

中文

我们已经发布 MasterGo Canvas for DeepSeek Harness：@mastergo/dsh-canvas。

它可以让 DeepSeek Harness 读取和修改同一台电脑上打开的 MasterGo Web 画布。安装包自带所需的本地运行程序，不要求安装 MasterGo 客户端，也不需要手动下载二进制或配置端口。

安装

需要 Node.js 22.19 或更高版本。

corepack enable
npx @deepseek-ai/dsh plugin --profile web add @mastergo/dsh-canvas
npx @deepseek-ai/dsh web

实际使用

1. 在同一台电脑上打开目标 MasterGo Web 文件。
2. 如果要处理现有内容，先在画布中选中页面、Frame 或节点；创建新内容时可以不选。
3. 在 Harness 会话中直接说明要做什么、有哪些限制、是否允许直接修改。

不需要记住插件名或工具名，可以直接这样说：

我选中了订单详情页。请总结它的页面层级、布局、间距、字体和组件复用情况。先分析，不要修改画布。

检查我选中区域的对齐、间距、字号层级和颜色使用，列出明显问题。同时截取当前区域供我核对，先不要修改。

在当前画布中做一个 1440 像素宽的 B2B 数据看板，包含顶部导航、四张指标卡、趋势图区域和订单表格。优先复用当前文件已有的组件和变量。先说明页面结构，再创建到画布中。

我已经选中顶部导航。保持整体尺寸和现有文案不变，增强当前菜单项状态，统一左右间距，并让操作按钮更突出。完成后告诉我改了什么。

推荐的完整流程是：打开文件并确认可以读取 → 选中现有页面并分析 → 确认修改方向 → 执行修改 → 再做一次截图和差异检查。

English

We have published MasterGo Canvas for DeepSeek Harness as @mastergo/dsh-canvas.

It lets DeepSeek Harness read and modify a MasterGo Web canvas open on the same computer. The package includes the required local runtime, so users do not need the MasterGo desktop client, a separate binary download, or manual port configuration.

Install

Node.js 22.19 or newer is required.

corepack enable
npx @deepseek-ai/dsh plugin --profile web add @mastergo/dsh-canvas
npx @deepseek-ai/dsh web

Practical usage

1. Open the target MasterGo Web file on the same computer.
2. When working with existing content, select the relevant page, frame, or nodes. Leave the selection empty when creating new content.
3. In the Harness conversation, describe the goal, constraints, and whether changes may be applied immediately.

There is no need to remember a plugin or tool name. You can say:

I selected the order-details page. Summarize its hierarchy, layout, spacing, typography, and component reuse. Analyze it first and do not change the canvas.

Check the selected area for alignment, spacing, type hierarchy, and color usage. List clear issues and capture the area for verification, but do not edit it yet.

Create a 1440-pixel-wide B2B analytics dashboard on the current canvas with a top navigation bar, four metric cards, a trend area, and an orders table. Reuse existing components and variables where possible. Explain the structure first, then create it.

I selected the top navigation. Keep its overall size and copy, strengthen the active-item state, make the horizontal spacing consistent, and give the action button more emphasis. Tell me what changed when you finish.

The recommended flow is: open the file and confirm access → select and analyze existing content → approve a direction → apply the change → run a final screenshot and difference review.
