MCP Server

A basic Model Context Protocol (MCP) server implementation in Python that provides utility tools for interacting with the file system and getting system information.

Features

This MCP server provides the following tools:

• hello_world: A simple greeting tool that accepts an optional name parameter
• get_time: Get the current time in various formats (ISO, timestamp, or readable)
• list_files: List files and directories in a specified path
• read_file: Read the contents of a text file

Installation

Prerequisites

• Python 3.13+
• uv package manager

Setup

1. Clone the repository:

git clone https://github.com/stef-codes/mcp-server.git
cd mcp-server

2. Install dependencies using uv:

uv sync

Usage

Run the MCP server:

uv run python main.py

The server will start and listen for MCP connections via stdio transport.

Available Tools

hello_world

Greets a user with an optional name parameter.

Parameters:

• name (string, optional): Name to greet (defaults to "World")

get_time

Returns the current time in the specified format.

Parameters:

• format (string, optional): Format type - "iso", "timestamp", or "readable" (defaults to "iso")

list_files

Lists files and directories in the specified path.

Parameters:

• path (string, optional): Directory path to list (defaults to current directory)

read_file

Reads and returns the contents of a text file.

Parameters:

• file_path (string, required): Path to the file to read

Development

The server uses a modular architecture:

• MCPServer class handles server initialization and tool registration
• Tools are implemented as async functions in tools.py
• The main.py file registers all tools and starts the server

To add new tools:

1. Implement the tool function in tools.py
2. Register it in main.py using mcp_server.register_tool()
