What it adds to DSH

Before you choose it

dsh-chart is the native DSH portion of search2chart-mcp. It is packaged as a DSH bundle and adds a chart plugin to the web profile, with the stated goal of converting structured data into inline charts in conversation.

Best for

DeepSeek Harness users who want chart output directly in web-profile conversations.

Common tasks

  • Turn tabular or structured data into an inline chart during a conversation.
  • Add the native chart plugin to a DSH web profile.
  • Present categories and numeric series visually instead of only as text.

Permissions and data

The supplied plugin description mentions a localhost HTTP service. No credential requirement is declared for the native DSH bundle.

Permissions
  • May use a localhost HTTP service as described by the plugin manifest.
Data handling
  • The supplied evidence does not document retention, transmission, or deletion behavior for chart input data.

Limitations

  • No Harness version range is declared.
  • No successful installation or runtime execution is evidenced.
  • The broader repository documents MCP and CDN features, but those behaviors are not verified here for the native DSH bundle.

What DSHub checked

  • Pinned Git source and DSH bundle structure were verified.
  • The bundle manifest declares the dsh-chart package and a peer dependency on @deepseek-ai/dsh-tools.
  • The patch supplies the web-profile add command.

What DSHub did not check

  • Installation in a real DSH environment was not executed.
  • Rendering behavior, localhost behavior, and data handling were not runtime-tested.

Pinned install

Install dsh-chart

This plugin bundle does not have a DSH Plugin install action. Use its source documentation for the delivery method.

search2chart-mcp

Turn any tabular data into inline charts directly inside agent conversations. Zero runtime dependencies, multi-client adaptive.

把「任意表格数据」变成直接内联在 agent 对话流里的图表。零运行时依赖,多端自适应。

安装

# 方式一:DSH 原生插件(DeepSeek Harness 用户推荐,真·内联)
dsh plugin --profile web add dsh-chart

# 方式二:npx(通用 MCP server,无需 clone)
npx search2chart-mcp

# 方式三:git clone
git clone https://github.com/iqingyoung/search2chart-mcp.git

两条路径

路径 目录 适用
通用 MCP server mcp/ ZCode / Claude Desktop / Cursor / WorkBuddy / Trae / Codex / DSH 通用
原生 DSH 插件 dsh/ DeepSeek Harness(真·内联,图片直接进对话)
  • 用 MCP 客户端 → 用 mcp/,对话框直接出图
  • 用 DSH 且想要原生体验 → 用 dsh/;DSH 里也能用 mcp/(走文件链接)
  • 两者可并存

快速开始

1. 在你的 MCP 配置里加入

{
  "mcpServers": {
    "search2chart-mcp": {
      "command": "npx",
      "args": ["search2chart-mcp"],
      "env": {}
    }
  }
}

如果 npx 拉不到,用 clone 后的绝对路径:"command": "node", "args": ["<仓库>/mcp/server.js"]

2. 首次接入:测试你的 Agent 能渲染哪种图片

不同 Agent 渲染器对图片格式支持各异。先用 all 模式一次性测试:

临时配置(在 MCP 配置里加环境变量):

{
  "env": {
    "ECHARTS_INLINE_MODE": "all"
  }
}

发给 Agent 的测试 prompt

用 chart_from_data 生成一个简单柱状图。
数据:[["城市","销量"],["北京",120],["上海",200],["广州",150]]
标题:城市销量对比
chartType:bar

Agent 返回 3-4 行图,分别标记为:

  • 【1·data URI】 — 自包含 base64,无需联网
  • 【2·localhost http】 — 本地 HTTP 服务
  • 【3·file://】 — 本地文件路径
  • 【4·CDN 公网 https】 — GitHub + jsDelivr 公网地址

哪个在对话框里真正渲染成了图片,你的 Agent 就支持哪种。

3. 固定模式

能渲染的格式 设置
data URI ✅ ECHARTS_INLINE_MODE=inline(默认)
file:// ✅ ECHARTS_INLINE_MODE=file
localhost http ✅ ECHARTS_INLINE_MODE=inline
CDN 公网 https ✅ ECHARTS_INLINE_MODE=cdn
MCP image block ✅ inline + 调用时 returnImage:true
都显示不了 ECHARTS_INLINE_MODE=none,用 .html 交互图

Agent 自动检测

工具结果里已内置 Agent 指令,告诉模型如何根据用户反馈自动设置模式:

[Agent]: 返回 4 行图片,哪张正常显示?
[User]:  3正常
[Agent]: 确认了。file:// 可渲染 → 请设置 ECHARTS_INLINE_MODE=file

已知客户端实测:ZCode → file,OpenCode → inline(data URI),WorkBuddy → cdn,DSH → inline(localhost http),Claude/Cursor → inline + returnImage:true

核心能力

多客户端内联适配

通过 ECHARTS_INLINE_MODE 环境变量控制内联行为:

模式 行为 适用客户端
inline(默认) data URI → localhost http → file:// 自动 fallback OpenCode / DSH / 通用
file 只输出 file:// 本地路径 ZCode
cdn 上传 GitHub+jsDelivr,输出公网 https WorkBuddy
all 测试模式:一次返回所有格式 首次接入时测试
none 纯文本(.html 路径 + 数据),无内联 纯文本模型 / 终端

CDN 公网图床

  • SVG → PNG 栅格化(@resvg/resvg-js,可选依赖)
  • GitHub Contents API 上传 + jsDelivr CDN 加速
  • GitHub Actions 定时清理(默认保留 3 天)

清洗数据留存

结果附带完整数据(JSON,代码块包裹),让纯文本模型在上下文里继续做占比/趋势/对比分析,无需看图。returnData: false 可关。

自包含可交互 HTML

图表同时写入 .html 文件,浏览器打开即支持 hover / 缩放 / 类型切换 / 配色调整。

工具

工具 作用
chart_from_data 结构化数据 → 图表 HTML + 内联图片
chart_from_file CSV/XLSX 路径 → 图表 HTML + 内联图片
list_chart_types 列出支持的类型 / 配色与字段约定

字段约定:第一列 = 类别轴;其余列 = 数值序列(多列即多序列);chartType: auto 按数据自动选 饼/柱。

接入各客户端
