Dice

A simple Model Context Protocol (MCP) server that enables Large Language Models (LLMs) to roll dice using standard dice notation (e.g., 1d20). This project demonstrates the extensibility and utility of MCP server implementations.

Features

• Accepts standard dice notation (such as 1d20) via JSON input.
• Returns both individual dice rolls and their sum.
• Designed for integration with LLMs and tools like Claude Desktop.
• Can be installed and run via command line or as part of a local development environment.
• Includes tests and development tools for debugging (e.g., MCP Inspector).
• Open-source and extensible for further customization.

Installation

• Can be installed automatically for Claude Desktop using Smithery.
• Requires uv for installation (see uv documentation).

Usage

• Accepts JSON input with a notation field indicating the dice roll (e.g., { "notation": "1d20" }).
• Returns structured results showing each roll and their sum.

Development

• Includes setup for installing development dependencies and running automated tests.
• Example configurations provided for Claude Desktop and different shell environments.
• Supports debugging with MCP Inspector.
