MCP Utility Tools

A lightweight collection of reusable utility tools for the Model Context Protocol (MCP).

Built using FastMCP and the Python standard library, this package provides common utilities that AI assistants and MCP clients can call without requiring external APIs or additional dependencies.

Features

• 📏 Unit Conversion
• 🔐 Secure Password Generator
• 📅 Date Calculator
• 🔑 Hash Generator
• 🔤 Base64 Encode / Decode
• 🆔 UUID Generator
• 🔄 Text Case Converter
• 📊 Text Statistics

Why this project?

This project was created as my first published PyPI package while learning the Model Context Protocol (MCP) ecosystem.

The goal was to build a practical MCP server exposing reusable utility tools using only Python's standard library.

Example

from mcp_utility_tools import main

main()

Example MCP tool call:

convert_units(
    value=5,
    from_unit="km",
    to_unit="mi"
)

Output:

5 km = 3.106856 mi
