mcp-randoom

A Model Context Protocol (MCP) server that provides true random generation tools for your AI agents. Whether you need an AI to make a decision for you, or you want it to act as a Dungeon Master for your next D&D session, mcp-randoom has you covered.

Features

• Coin Flip: Let the AI decide your fate with a secure 50/50 coin toss. Perfect for "Heads or Tails" scenarios.
• Dice Roller: A robust dice roller supporting standard D&D notation (e.g., 1d20, 2d6, 4d8). Great for TTRPG sessions where the AI plays the DM or a player.
• True Random Numbers: Generate cryptographically secure random integers or floating-point numbers within a specified range.
• Wheel of Fortune: Spin a virtual wheel to randomly select an item from a list of options (great for raffles or decision making).
