MCP Server Basic Example

This is a basic example of a Model Context Protocol (MCP) server implementation that demonstrates core functionality including tools and resources.

Setup Steps

  1. Initialize the project (Go to any local folder and launch powershell or cmd):
uv init mcp-server-basic cd mcp-server-basic

  1. Create virtual environment and activate it

uv venv .venv\Scripts\activate
  1. Install dependencies:
uv add "mcp[cli]"

or

uv add -r requirements.txt

Features

The server implements the following features:

Tools

  • add(a: int, b: int): Adds two numbers
  • subtract(a: int, b: int): Subtracts second number from first

Resources

  • greeting://{name}: Returns a personalized greeting

Running the Server

To run the server with the MCP Inspector for development:

uv run mcp dev main.py

To run the server normally:

uv run mcp run

To install the server in Claude desktop app:

uv run mcp install main.py

MCP connect in VS code

  • Open folder/mcp-server-basic in vs code
  • open terminal and run below command :
uv run main.py
  • Click Cntrl+Shift+I to launch chat in vs code
  • Do login with Github and setup
  • Folow the below steps (two way to add mcp configuration for vs code user settings):

#hello from mcp
