How to Set Up and Use MCP Client Server Node.js
This project is a minimal, educational Model Context Protocol implementation built with Node.js and TypeScript. It demonstrates the core MCP client-server communication pattern over stdio, including structured message handling and local JSON data access. It is ideal for developers who want to understand how MCP works before building their own servers.
Prerequisites
- Node.js 18 or later installed
- npm or yarn package manager
- TypeScript knowledge (basic)
- Git to clone the repository
- VS Code recommended (the project was developed with Copilot integration)
Clone the repository
Clone the MCP Client-Server Node.js project from GitHub to your local machine.
git clone https://github.com/dyneth02/MCP-Client-Server-Project-using-NodeJS.git
cd MCP-Client-Server-Project-using-NodeJSInstall dependencies
Install Node.js dependencies defined in package.json.
npm installBuild the TypeScript source
Compile TypeScript files to JavaScript in the build output directory.
npm run buildStart the MCP server
Launch the server process. It reads from users.json and listens for client messages over stdio.
node build/server.jsRun the MCP client
In a separate terminal, start the client to connect to the server and send structured MCP requests.
node build/client.jsMCP Client Server Node.js Examples
Client configuration
Configure Claude Desktop or another MCP host to launch this server directly.

}Prompts to try
Use Claude to interact with the local users.json data exposed by the server.
- "List all users available in the local data source."
- "Find the user with ID 3 and tell me their name and email."
- "How many users are stored in the server's data file?"
- "Explain how this MCP server handles client requests over stdio."Troubleshooting MCP Client Server Node.js
TypeScript compilation fails with type errors
Ensure TypeScript is installed (`npm install -g typescript` or use the local version via `npx tsc`). Check tsconfig.json targets Node 18+ and that all dependencies are installed.
Server exits immediately after starting
Verify users.json exists in the expected location relative to server.js. The server reads this file at startup and will crash if it is missing or malformed.
Client cannot connect to server
Both client and server must be started from the project root directory so relative paths resolve correctly. Confirm the server is running before launching the client.
