MCP Examples

This repository contains examples and implementations for the Model Context Protocol (MCP). The examples are designed to demonstrate how to build and use MCP servers and tools effectively.

Repository Structure

The repository is organized as follows:

mcp-node-examples/
  echo/
    index.ts
    package.json
    tsconfig.json

mcp-node-examples/echo

This folder contains an example implementation of an MCP server using Node.js. The server includes a simple tool called echo_tool that echoes back the input provided by the client.

Files:

• index.ts: The main entry point for the echo server implementation.
• package.json: Contains the dependencies and scripts for the Node.js project.
• tsconfig.json: TypeScript configuration file.

   cd mcp-examples/mcp-node-examples/echo
   

2. Install dependencies:
