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 🙏

帮助你快速构建拥有 MCP 能力的 Agent

一、基本用法

依赖安装

npm i @seepine/ai

创建 Agent

import { ChatOpenAI, Agent } from '@seepine/ai'

const agent = new Agent({
  baseURL: process.env['OPENAI_BASE_URL'],
  apiKey: process.env['OPENAI_API_KEY']!,
  model: process.env['OPENAI_MODEL']!,
  prompts: [
    {
      // 使用提示词构建 agent
      role: 'system',
      content: '你是一个中英文翻译专家,将用户输入的中文翻译成英文,或将用户输入的英文翻译成中文',
    },
  ],
})

agent.chatSync('荣誉').then((res) => {
  // 输出结果 Honor
  console.log(res)
})

流式输出

for await (const chunk of agent.chat(input)) {
  if (chunk.type === 'chat') {
    process.stdout.write(chunk.content)
  } else {
    console.log(chunk)
  }
}

二、使用 MCP

创建 MCP

import { McpClient } from '@seepine/ai'

// 这是获取网页内容和bing搜索的mcp
const fetchMCP = new McpClient({
  name: 'mcp-server-fetch',
  type: 'stdio',
  command: 'npx',
  args: ['-y', '@seepine/mcp-fetch'],
})

创建 Agent

import { ChatOpenAI, Agent, McpClient } from '@seepine/ai'

const agent = new Agent({
  baseURL: process.env['OPENAI_BASE_URL'],
  apiKey: process.env['OPENAI_API_KEY']!,
  model: process.env['OPENAI_MODEL']!,
  // 传给 Agent
  mcps: [fetchMCP],
})

使用

for await (const chunk of agent.chat(input)) {
  if (chunk.type === 'chat') {
    process.stdout.write(chunk.content)
  } else if (chunk.type === 'tool_call_begin') {
    // 开始调用mcp
  } else if (chunk.type === 'tool_call_end') {
    // 调用mcp结束
  }
}
