README

ELN MCP Server

ELN 数据管理平台表单设计 MCP Server。

快速开始

1. 安装依赖

cd d:\github\trae\formily\eln-mcp-server
npm install
npx playwright install chromium

2. 编译

npm run build

3. 配置到 AI 客户端

将以下配置添加到你的 AI 客户端的 MCP 配置文件中:

{
  "mcpServers": {
    "eln-form-design": {
      "command": "node",
      "args": ["d:\\github\\trae\\formily\\eln-mcp-server\\dist\\index.js"],
      "env": {
        "ELN_BASE_URL": "http://10.1.228.52:13002/api/v1",
        "ELN_USERNAME": "admin",
        "ELN_PASSWORD": "qwert123",
        "ELN_HEADLESS": "true"
      }
    }
  }
}

4. 各客户端配置文件位置

AI 客户端 配置文件路径 格式
TRAE ~/.trae-cn/mcp_config.json 同上方 JSON
Claude Desktop %APPDATA%\Claude\claude_desktop_config.json 同上方 JSON
Cursor ~/.cursor/mcp_config.json 同上方 JSON
VS Code (Copilot) .vscode/mcp.json 同上方 JSON

5. 环境变量说明

变量 默认值 说明
ELN_BASE_URL http://10.1.228.52:13002/api/v1 ELN 服务器 API 地址
ELN_USERNAME admin 登录用户名
ELN_PASSWORD qwert123 登录密码
ELN_HEADLESS true Playwright 无头模式(false=显示浏览器窗口)
ELN_TOKEN_CACHE (系统临时目录) Token 缓存文件路径

6. Skill 文件部署

Skill 文件位于 d:\github\trae\formily\eln-skills\ 目录。将此目录路径告知 AI 客户端:

  • TRAE: 在项目 .trae 配置中添加 skills 路径
  • Claude Desktop: 放入 ~/.claude/skills/ 目录
  • Cursor: 在项目 AGENTS.md 中引用路径

使用流程

1. 对 AI 说: "帮我登录 ELN 系统"
   → AI 调用 login 工具

2. 对 AI 说: "创建一个矿渣粉重量分析模板"
   → AI 调用 list_categories → create_template → add_component → add_formula → save_template

3. 对 AI 说: "查看系统里有哪些模板"
   → AI 调用 list_templates

4. 对 AI 说: "修改模板 258 的公式"
   → AI 调用 select_template → list_formulas → add_formula → save_template
