介绍
- 基于MCP协议,基于TypeScript语言开发简单实现
- 支持本地Stdio MCP及远程Streamable HTTP MCP服务
- 支持AI Agent,如Claude、Cline、LINGMA灵码等MCP智能工具
- 本项目仅为MCP协议示例项目,可参考项目进行更多开发
- 更多参考官方文档:https://modelcontextprotocol.io
- 项目未来会持续迭代更多示例

如何运行
-
本地执行完
npm run start-http命令后,就已经构建了本地stdio文件,及启动了http服务 <br/> <img src="./doc/assets/img-start-http.png" alt="start-http" width="750"> <br/> -
配置AI Agent MCP服务,这里以VSCode LINGMA灵码为例,其他智能工具可参考对应文档进行配置 其中
mcp-ts-stdio-server为stdio服务,mcp-ts-http-server为http服务,注意本地路径args要正确
{
"mcpServers": {
"mcp-ts-stdio-server": {
"command": "node",
"args": [
"/Users/zcy/pjqdyd/mcp-ts-demo/dist/index.js"
],
"env": {
"MCP_SERVER_NAME": "mcp-ts-server",
"MCP_SERVER_VERSION": "1.0.0"
}
},
"mcp-ts-http-server": {
"type": "streamable_http",
"url": "http://localhost:3000/mcp"
}
}
}
- 配置完成后,AI工具将自动连接MCP服务,并识别出服务提供的工具 <br/> <img src="./doc/assets/img-mcp-config.png" alt="start-http" width="750"> <br/>
- 配置完成,并且AI工具正确连接MCP服务后,即可进行MCP服务工具调用,输入“执行 say hello to 小明” <br/> <img src="./doc/assets/img-say-hello.png" alt="start-http" width="750"> <br/> 运行执行后,AI工具将返回工具调用的结果。
总结
- MCP(模型上下文协议)是一个开源标准,用于将人工智能应用与外部系统连接起来。
- MCP协议是一种用于构建智能工具和AI服务的协议,它允许工具和AI服务之间进行交互,并使用MCP协议进行数据传输。
- 通过MCP,像Claude或ChatGPT这样的AI应用可以连接数据源(如本地文件、数据库)、工具(如搜索引擎、计算器)和工作流程(如专门提示)——使它们能够访问关键信息并执行任务。
