Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MCP server for Schema Page RAG integration with Cursor

Readme

Schema Page RAG Server

MCP 服务,能够解答与 Schema Page、Schema Form、Schema Chart 相关的组件用法和代码编写问题,将用户输入转发到 Langflow 处理,并将结果返回给 Cursor Agent。

功能特点

  • 通过 MCP 协议与 Cursor 集成
  • 专注于解答 Schema 相关组件问题
  • 支持多种 Schema 类型:Form、Page、Chart 等
  • 提供组件使用示例和代码片段
  • 支持自定义 Flow ID
  • 友好的错误处理

安装方法

方法一:通过 NPM 安装(推荐)

npm install -g schema-page-rag

方法二:手动安装

  1. 克隆仓库
  2. 安装依赖:npm install
  3. 构建项目:npm run build

配置说明

在 Cursor 中配置

将以下配置添加到.cursor/mcp.json文件中:

{
  "mcpServers": {
    "langflow-rag": {
      "command": "npx",
      "args": ["schema-page-rag"]
    }
  }
}

使用示例

在 Cursor 中,你可以通过以下方式调用 schema-page-rag 工具:

<function_calls>
<invoke name="mcp__langflow_rag">
<parameter name="prompt">如何使用OKSchemaForm构建一个包含级联选择器的表单?</parameter>
<parameter name="flowId">可选的Flow ID</parameter>
</invoke>
</function_calls>

触发条件

当用户查询包含以下关键词时,将触发此服务:

  • schema-page、schema-form、schema-chart
  • schemapage、schemaform、schemachart
  • okschemaform、okschemapage、okschemachart
  • 表单 schema、schema 表单、json schema、formschema
  • 动态表单、表单配置、表单组件
  • 图表 schema、图表配置

注意事项

  • 确保 Langflow 服务已启动并能够正常访问
  • 默认连接到http://127.0.0.1:7860/api/v1/run
  • 如需修改默认的 Langflow API 地址,请编辑源码中的配置

单元测试

项目包含全面的单元测试,可以通过以下命令运行测试:

# 运行所有测试
npm test

# 监视模式运行测试
npm run test:watch

# 运行测试并生成覆盖率报告
npm run test:coverage

测试覆盖了以下主要功能:

  • 关键词匹配功能 - 验证能正确识别 Schema 相关查询
  • 环境变量处理 - 测试额外关键词和 tweaks 配置的正确加载
  • API 调用逻辑 - 测试与 Langflow API 的交互,包括错误处理

添加新测试

src/__tests__目录下添加新的测试文件,保持命名格式为*.test.ts

使用 Jest 的断言和模拟功能测试新功能,确保所有重要的业务逻辑都有相应的测试覆盖。
