Setup snapshot

git clone https://github.com/leytonliu/leyton-library.git

1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

leyton-library

一个功能丰富的 TypeScript 工具库，提供多种实用工具和 MCP (Model Context Protocol) 服务器功能。

📦 安装

# 使用 npm
npm install leyton-library

# 使用 pnpm
pnpm add leyton-library

# 使用 yarn
yarn add leyton-library

🚀 快速开始

基础工具函数

import { sayHello, setupCounter, PromiseQueue, union, intersection, encodeBase64, E2EEncryption } from 'leyton-library';

// 基础工具
sayHello(); // 输出: Hello

// DOM 操作
const button = document.querySelector('#counter') as HTMLButtonElement;
setupCounter(button);

// 数组操作
const arr1 = [1, 2, 3];
const arr2 = [2, 3, 4];
console.log(union(arr1, arr2)); // [1, 2, 3, 4]
console.log(intersection(arr1, arr2)); // [2, 3]

// Base64 编码
const encoded = encodeBase64('hello world'); // "aGVsbG8gd29ybGQ="

// Promise 队列
const queue = new PromiseQueue(2); // 最大并发数 2
queue.add(() => fetch('/api/data1'));
queue.add(() => fetch('/api/data2'));

// 端到端加密
const alice = new E2EEncryption();
const bob = new E2EEncryption();
await alice.generateKeys();
await bob.generateKeys();

const message = 'Hello, this is a secret message!';
const encrypted = await alice.encrypt(message, bob.getPublicKey());
const decrypted = await bob.decrypt(encrypted);
console.log(decrypted); // "Hello, this is a secret message!"

MCP 服务器

启动 MCP Base64 编码服务器：

# 使用 npx（推荐）
npx leyton-library@latest mcp-server

# 或者使用特定版本
npx leyton-library@0.0.7 mcp-server

🛠️ 功能模块

1. sayHello

简单的问候函数，用于测试和演示。

import { sayHello } from 'leyton-library';
sayHello(); // 输出: Hello

2. main (DOM 操作)

提供 DOM 元素操作功能，特别是计数器功能。

import { setupCounter } from 'leyton-library';

const button = document.querySelector('#counter') as HTMLButtonElement;
setupCounter(button);

3. promise-queue

Promise 队列管理，支持并发控制。

import { PromiseQueue } from 'leyton-library';

const queue = new PromiseQueue(2); // 最大并发数 2

// 添加任务
queue.add(async () => {
  const response = await fetch('/api/data');
  return response.json();
});

// 等待所有任务完成
const results = await queue.waitForAll();

4. array

数组操作工具函数。

import { union, intersection } from 'leyton-library';

const arr1 = [1, 2, 3];
const arr2 = [2, 3, 4];

// 并集
const unionResult = union(arr1, arr2); // [1, 2, 3, 4]

// 交集
const intersectionResult = intersection(arr1, arr2); // [2, 3]

5. mcp-base64

MCP 服务器和 Base64 编码工具。

工具函数

import { encodeBase64 } from 'leyton-library';

const encoded = encodeBase64('hello world'); // "aGVsbG8gd29ybGQ="

MCP 服务器

import { createMcpBase64Server, startMcpBase64Server } from 'leyton-library';

// 创建服务器
const server = await createMcpBase64Server();

// 启动服务器
const { server, transport } = await startMcpBase64Server();

6. crypto (端到端加密)

基于 Web Crypto API 实现的端到端加密模块，使用 RSA-OAEP + AES-GCM 混合加密。

高级 API（推荐）

import { E2EEncryption } from 'leyton-library';

// 创建两个用户
const alice = new E2EEncryption();
const bob = new E2EEncryption();

// 生成密钥对
await alice.generateKeys();
await bob.generateKeys();

// Alice 发送加密消息给 Bob
const message = 'Hello Bob, this is a secret message!';
const encrypted = await alice.encrypt(message, bob.getPublicKey());

// Bob 解密消息
const decrypted = await bob.decrypt(encrypted);
console.log(decrypted); // "Hello Bob, this is a secret message!"

低级 API

import { 
  generateRSAKeyPair, 
  exportKeyPair, 
  encryptData, 
  decryptData 
} from 'leyton-library';

// 生成密钥对
const keyPair = await generateRSAKeyPair();
const { publicKey, privateKey } = await exportKeyPair(keyPair);

// 加密数据
const message = 'Secret message';
const encrypted = await encryptData(message, publicKey);

// 解密数据
const decrypted = await decryptData(encrypted, privateKey);

特性

✅ 混合加密：RSA-OAEP-256 + AES-GCM-256
✅ 浏览器原生：基于 Web Crypto API
✅ 认证加密：AES-GCM 提供完整性验证
✅ 前向保密：每次加密使用新的随机密钥
✅ 标准格式：PEM 格式密钥导入导出

🔧 MCP 服务器配置

Cursor 集成

在 Cursor 的 MCP 配置文件中添加：

{
  "mcpServers": {
    "base64-server": {
      "command": "npx",
      "args": ["leyton-library@latest", "mcp-server"]
    }
  }
}

可用的 MCP 工具

base64_encode: 将输入文本进行 Base64 编码
- 参数: { text: string }
- 返回: 编码后的 base64 字符串
