What is Mcp Hello World Ts

mcp-hello-world-ts is a minimal Model Context Protocol (MCP) server written in TypeScript. It serves as a demonstration of creating MCP-compliant resources and tools for use with LLMs and MCP-enabled clients like Claude Desktop.

Use cases

Use cases include creating chatbots, developing interactive tools for LLMs, and integrating with applications that support the Model Context Protocol.

How to use

To use mcp-hello-world-ts, first install the necessary dependencies using ‘npm install’. Then, build the project with ‘npm run build’ and start the server using ‘npm start’. You can also configure it as a plugin/tool in MCP clients like Claude Desktop.

Key features

Key features include simple MCP resources at ‘hello://greeting’, ‘hello://info’, and ‘hello://list’, a ‘helloTool’ that echoes messages, and Stdio Transport for easy integration with MCP clients.

Where to use

mcp-hello-world-ts can be used in applications that require interaction with LLMs and MCP-enabled clients, particularly in environments where simple resource management and communication are needed.

Getting Started

Prerequisites

• Node.js (v18+ recommended)
• npm (comes with Node.js)

---

Install Dependencies

npm install

---

Build the Project

Compile TypeScript source files to JavaScript in the dist/ directory:

npm run build

---

Run the Server (Standalone)

npm start

This will start the MCP server via Node.js using the built output.

---

Run Tests

Integration tests are provided to verify the MCP server works end-to-end:

npm test

This runs the tests in src/integration.test.ts using Jest.

---

Using with Claude Desktop

You can configure Claude Desktop or any MCP client to use this server as a plugin/tool by specifying the command to launch the MCP server.

Example Configuration Snippet

Add the following to your Claude Desktop settings (replace the path with your actual project path):

• Replace /path/to/mcp-hello-world-ts/ with the full path to where you cloned this repo.
• Make sure you have built the project (npm run build) before starting Claude Desktop.
