项目简介

本项目基于 modelcontextprotocol/typescript-sdk 实现 Markdown 转 HTML 的 MCP 服务端,支持 npx/全局命令一键启动、远程 HTTP/Streamable HTTP 调用,并可被 Cursor 等 MCP 客户端直接调用。

特性

  • 支持 ESM/CJS 双产物,适配多种 Node.js 环境
  • 一键 npx/全局命令启动(stdio)
  • 支持 HTTP/Streamable HTTP 服务
  • 结构现代,类型安全,源码位于 src/,产物位于 dist/(ESM)和 dist-cjs/(CJS)
  • bin/主入口均指向 CJS 产物,兼容性强
  • 可被 Cursor、curl、代码等多种方式远程调用

快速开始

安装依赖

npm install

构建产物

npm run build

本地启动(stdio)

npx ts-node src/cli.ts
# 或
npm run start

启动 HTTP 服务

npx ts-node src/cli.ts --http
# 或
node dist-cjs/cli.js --http

作为全局命令/被 Cursor 调用

npx @hun-dun/markdown-to-html-mcp
# 或
markdown-to-html-mcp

远程 HTTP/Streamable HTTP 调用

curl -X POST http://localhost:3000/mcp -H 'Content-Type: application/json' -H 'Accept: application/json, text/event-stream' -d '{"tool":"markdownToHtml","input":{"markdown":"# Hello"}}'

ESM/CJS 产物说明

  • ESM 产物位于 dist/,入口 dist/index.js
  • CJS 产物位于 dist-cjs/,入口 dist-cjs/index.js
  • bin/主入口均指向 CJS 产物,兼容 npx/全局命令

MCP 工具注册与调用

  • registerMarkdownToHtmlTool(server) 注册 markdownToHtml 工具,参数为 markdown,返回 HTML。
  • CLI 支持 stdio 和 HTTP 两种模式。

在 Cursor 中调用

本工具可直接集成到 Cursor,支持本地(stdio)和远程(http)两种方式:

方式一:本地调用(stdio,推荐本地开发/临时调用)

.cursor/config.json 中添加如下配置:

{
  "mcp": [
    {
      "name": "@hun-dun/markdown-to-html-mcp (本地 npx)",
      "type": "stdio",
      "command": "npx",
      "args": ["@hun-dun/markdown-to-html-mcp"]
    }
  ]
}
  • Cursor 会自动用 npx 下载并调用你的包,适合本地/临时场景。
  • 不需要你手动启动服务端。
  • 结果会直接在 Cursor 工具面板中展示。

方式二:远程调用(http,推荐云端/团队共享)

  1. 启动 HTTP 服务:
    npx @hun-dun/markdown-to-html-mcp --http
    # 或 PORT=8080 npx @hun-dun/markdown-to-html-mcp --http
    
  2. .cursor/config.json 中添加如下配置:
{
  "mcp": [
    {
      "name": "@hun-dun/markdown-to-html-mcp (remote)",
      "type": "http",
      "url": "http://localhost:3000/mcp"
    }
  ]
}
  • 适合你用 npx @hun-dun/markdown-to-html-mcp --http 启动服务后,供多台机器/团队成员/云端调用。
  • 结果会直接在 Cursor 工具面板中展示。

常见问题

  • ts-node 运行 .ts 文件报 "Unknown file extension .ts"——需加 --loader ts-node/esm
  • node 运行 dist/index.js 报 "exports is not defined in ES module scope"——需用 CommonJS 产物并移除 package.json 的 "type": "module",或用 .cjs 后缀
  • StreamableHTTPServerTransport 构造参数报错,需根据 SDK 版本传递正确 options

适用场景

  • 本地开发、测试
  • 远程 HTTP/Streamable HTTP 服务
  • Cursor、MCP 客户端一键集成
  • 代码/脚本/命令行调用
