Overview

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.
