概要

What is MCP Add Server?

MCP Add Server is a minimal Model Context Protocol (MCP) server that provides a single tool: add(a, b), which returns the sum of two numbers. It serves as a basic example of an MCP server implementation, intended for developers learning about the MCP ecosystem or testing MCP-compatible clients.

How to use MCP Add Server?

Run the server using npx mcp-add-server (requires Node.js 18+ and npm). Alternatively, clone the repository, install dependencies with npm install, and run with npm start. You can also install it globally via npm install -g mcp-add-server or use npm link for local development. Once running, MCP clients can call the add tool with arguments a and b and receive the sum as the result.

Key features of MCP Add Server

  • Implements a Model Context Protocol compliant server.
  • Provides a single add(a, b) tool that returns numeric sums.
  • Can be run via npx, local clone, or global installation.
  • Requires only Node.js 18.x or higher and npm.
  • Includes both a server executable (bin.js) and modular source code (src/server.js).
  • Licensed under the MIT License.

Use cases of MCP Add Server

  • Learning how to build a minimal MCP server from scratch.
  • Testing MCP client tool‑calling functionality.
  • Demonstrating MCP server–client integration in workshops or documentation.
  • Quick validation of MCP tool invocation pipelines.
