Overview

AI-generated overview

Local MCP server that turns tabular data or CSV/XLSX files into ECharts charts, returning interactive HTML files and inline images in the chat.

What you can do
  • Generate charts from structured data or from CSV/XLSX file paths, producing an interactive HTML file plus an inline image.
  • List supported chart types, color schemes and field conventions, with automatic pie/bar selection when the type is set to auto.
  • Choose how images are returned: data URI, localhost HTTP, file path, public CDN link, MCP image block, or plain text with the HTML path.
  • Return the cleaned data as JSON alongside the chart so text-only models can keep analyzing proportions and trends.
When to use it
Useful when an assistant needs to visualize tabular results inside a conversation, for example turning query output or a spreadsheet into a bar or pie chart, or producing a standalone interactive HTML chart to open in a browser.
Requirements
Runs locally over stdio, typically launched with npx search2chart-mcp (Node.js) or a cloned server.js path. Optional ECHARTS_INLINE_MODE environment variable selects the image output mode; no accounts or API keys are declared.
Before you install
The cdn mode uploads generated charts to GitHub via the GitHub Contents API and serves them through a public CDN, so chart images leave your machine; scheduled cleanup keeps them about three days. Chart output is also written to local .html files. Rendering support differs per client, so test the output mode first.

Installation

In SourceWeft

  1. Open Search2chart Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

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

bash
# 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 clonegit clone https://github.com/iqingyoung/search2chart-mcp.git

两条路径

路径目录适用
通用 MCP servermcp/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

json
{  "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):

json
{  "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 fallbackOpenCode / DSH / 通用
file只输出 file:// 本地路径ZCode
cdn上传 GitHub+jsDelivr,输出公网 httpsWorkBuddy
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_fileCSV/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。
