This is a minimal example of a JavaScript project using the Model Context Protocol (MCP) to build server-client applications.
🚀 MCP Sample for JavaScript 🌟
Welcome to the smallest possible example of a JavaScript project using the MCP! This repo is your starting point for building amazing projects with MCP. 🛠️✨
[!NOTE] The client should ideally integrate with an LLM to negotiate with the server on what tools to call and what resources to access. 🤖💬. That's not the case here and the client explicitly call the server and asks about its tools and resources and more.
[!IMPORTANT] Install and build the server before running the client. 🏗️🚀
🌐 Server
The server uses StdioServerTransport and includes the following:
- 🧮
add: A tool that takes two numbers,aandb, and returns their sum. - 👋
greeting/{name}: A resource template that takes a name and returns a friendly greeting.
📦 Install Server
Build the server with this command:
npm install
▶️ Run Server
Start the server with this command:
npm build
🕵️♂️ Test the Server with the Inspector Tool
Use the inspector tool to test the server! 🛠️ Open it with:
npm run inspect
This will connect to the server and launch a user interface in your browser. 🌐 Use the inspector tool to call tools, access resources, view logs, and more! 🎉
💻 Client
The client is located in the client folder. 📂
📦 Install Client
Change directory to the client folder with this command:
cd client
Install the client with this command:
npm install
▶️ Run Client
Start the client with this command:
npm start
Enjoy building your MCP-powered JavaScript projects! 🚀✨
