A simple MCP server that provides an add_numbers tool to perform basic numeric addition and demonstrate MCP concepts.

Example Use Cases

1
Perform simple arithmetic operations via an MCP-exposed tool (e.g., calculate 42 + 17).
2
A minimal, working example of registering tools, resources (including dynamic ResourceTemplate URIs), and prompts in an MCP server.
3
Integrate and test a local MCP server with Claude desktop and debug using the MCP Inspector.

Description

This repository implements a minimal MCP (Model Context Protocol) server exposing an add_numbers tool for summing two numbers. It demonstrates registering tools, defining resources (including parameterized ResourceTemplate), and creating prompts, plus instructions for running and debugging with the MCP Inspector. The README shows how to integrate the server with Claude desktop for testing. It's intended as an educational/example project for developers learning to build MCP servers.
