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 🙏

TTLive Campaign MCP 服务

这是一个为 TTLive Campaign 团队提供 MCP (Meta Call Protocol) 能力的仓库。

当前示例:计算器服务

此仓库目前包含一个简单的计算器 MCP 服务作为示例。

功能

计算器服务支持以下操作:

  • 加法 (add)
  • 减法 (subtract)
  • 乘法 (multiply)
  • 除法 (divide)

如何构建和运行

  1. 构建服务: 在仓库根目录下运行以下命令来编译 Go 程序:

    go build -o mcp_server main.go
  2. 运行服务并发送请求: 在仓库根目录下,运行编译后的服务器,并通过管道将 req.json 的内容作为输入:

    go build -o mcp_server main.go
    ./mcp_server

    输入:

    {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"calculate","arguments":{"operation":"multiply","x":3,"y":5}}}
  3. 预期输出: 对于上述 req.json 中的请求,预期的输出将是:

    {"jsonrpc":"2.0","id":1,"result":{"content":[{"type":"text","text":"15.00"}]}}

添加新的 MCP 工具

要扩展此服务的功能,您可以:

  1. main.go 中定义新的工具和处理函数,类似于 calculatorToolcalculate 函数。
  2. 使用 s.AddTool() 将新工具及其处理函数注册到 MCP 服务器实例。
