How to Set Up and Use MCP Client And
MCP Client and Server is a TypeScript monorepo demonstration that implements both sides of the Model Context Protocol in a single Nx workspace. It provides a working reference for developers learning how to build MCP servers and the clients that consume them, showing how tool definitions, request handling, and response formatting connect end-to-end. Engineers new to MCP use this project to understand the full request lifecycle before building their own production integrations.
Prerequisites
- Node.js 18 or later
- pnpm package manager installed globally (`npm install -g pnpm`)
- An MCP-compatible client such as Claude Desktop to test the server side
- Basic familiarity with TypeScript and the Model Context Protocol specification
Clone the repository
Clone the monorepo to your local machine and enter the project directory.
git clone https://github.com/jherr/mcp-client-and-server.git
cd mcp-client-and-serverInstall dependencies with pnpm
The project uses pnpm workspaces to manage both the client and server packages. Install all dependencies from the root.
pnpm installBuild the project
Use Nx to build all apps in the workspace. This compiles the TypeScript for both the MCP server and the demo client.
pnpm nx run-many --target=build --allStart the MCP server
Run the server app. It will start and wait for MCP client connections over stdio, making its demo tools available.
pnpm nx serve serverAdd the server to Claude Desktop for testing
Register the built server binary in your Claude Desktop config to test it with a real MCP client.

Example prompts for exploring the demo MCP server's capabilities.
- "What tools does this MCP server expose?"
- "Call the demo tool and show me its response."
- "List all available MCP tools and describe what each one does."
- "Run the example tool with a test input and explain the result."Troubleshooting MCP Client And
pnpm install fails with workspace protocol errors
Ensure you are running pnpm version 8 or later. Older pnpm versions do not fully support the workspace: protocol used in this monorepo. Upgrade with `npm install -g pnpm@latest`.
Nx build command is not found
Nx is installed as a local dev dependency. Use `pnpm nx` (with the pnpm prefix) instead of a global `nx` command, or add `./node_modules/.bin` to your PATH.
Claude Desktop does not see the server's tools
Verify the path in your MCP config points to the compiled dist/main.js output, not the TypeScript source. Run the build step first and confirm the dist directory exists before restarting Claude Desktop.
