MCP Server

A simple Model Context Protocol (MCP) server implementation that provides tool functionality through a standardized interface. This server currently implements a basic calculator tool that can add two numbers together.

Overview

This server uses the @modelcontextprotocol/sdk to create a standardized way of exposing tools to MCP clients. It runs over stdio transport, making it suitable for integration with various client applications.

Features

Implements MCP Server specification
Uses stdio transport for communication
Provides a calculate_sum tool that adds two numbers together

Available Tools

calculate_sum

A simple addition tool that takes two numbers and returns their sum.

Input Schema:

{
  "type": "object",
  "properties": {
    "a": { "type": "number" },
    "b": { "type": "number" }
  },
  "required": ["a", "b"]
}

Response: The tool will return the sum as a text response. For example, "8" for the above input.

Technical Details

Server Name: mcp-server
Version: 1.0.0
Transport: StdioServerTransport
SDK: @modelcontextprotocol/sdk

Getting Started

Install dependencies:

npm|yarn|pnpm install @modelcontextprotocol/sdk

Run the server:

Meant to be used with an MCP client, for example this one. Usage with that client would look like this:

npm|yarn|pnpm start <path_to_this_dir/build/index.js>

Error Handling

The server implements standard MCP error handling. If an unknown method is called, it will return a MethodNotFound error.
