Overview

What is MCP Server Basic Example?

MCP Server Basic Example is a minimal reference implementation of the Model Context Protocol (MCP) server in Python. It demonstrates core MCP capabilities—tools and resources—and is intended for developers learning how to build MCP servers.

How to use MCP Server Basic Example?

Initialize a project with uv init mcp-server-basic, create a virtual environment, and install mcp[cli]. Run the server for inspection with uv run mcp dev main.py, or normally with uv run mcp run. To install in Claude Desktop, use uv run mcp install main.py. For VS Code, run uv run main.py then open the chat with Ctrl+Shift+I.

add(a, b) tool: adds two integers
subtract(a, b) tool: subtracts second integer from first
greeting://{name} resource: returns a personalized greeting
Fully compatible with MCP Inspector and Claude Desktop
Minimal Python implementation using uv as package manager
