Dice Roll MCP Server のツール

Parses dice roll notation

Make a dice roll

概要

What is Dice Roll?

An MCP (Model Context Protocol) server that simulates dice rolls using standard dice notation and Fate/Fudge dice. It provides tools for parsing dice notation strings and generating random results, designed for use with MCP-compatible clients like Claude Desktop.

How to use Dice Roll?

Install globally with npm install -g server-dice-roll or run directly via npx -y server-dice-roll. Configure in Claude Desktop by adding the server to mcpServers in the configuration file. The server exposes two tools: parse_dice_roll_notation (parses a notation string to structured data) and dice_roll (rolls dice based on a configuration and returns results).

Key features of Dice Roll

Parses standard dice notation strings (e.g., 2d6, 1d20+5)
Supports both standard dice and Fate/Fudge dice
Generates random dice rolls with accurate probability distributions
Validates input and output using Zod schemas
Seamlessly integrates with any MCP-compatible client

Use cases of Dice Roll

Add dice rolling to a tabletop RPG assistant via Claude Desktop
Simulate Fate/Fudge dice rolls for narrative games
Parse and validate dice notation in applications that need structured roll data
Enable random number generation through MCP for automation tools

よくある質問

What dice notation formats are supported?

Standard notation `NdS+M` (e.g., `2d10`, `3d8+5`) and Fate dice notation `NdF` (e.g., `4dF`). The number of dice defaults to 1 if omitted, and the modifier is optional.

How do I install and run this server?

Install globally via `npm install -g server-dice-roll` and run `mcp-server-dice-roll`, or use `npx -y server-dice-roll` without installation. Configure in Claude Desktop by adding the server block with `"command": "npx", "args": ["-y", "server-dice-roll"]`.

Can I parse a dice notation string without rolling?

Yes, use the `parse_dice_roll_notation` tool. It takes a notation string like `"3d6+4"` and returns a structured object with `type`, `count`, `sides`, and `modifier`.

What are Fate/Fudge dice and how do I use them?

Fate dice are 6-sided with two sides each of -1, 0, and +1. Use `NdF` notation (e.g., `4dF`). The server's dice rolling tool accepts `type: "fudge"` in the configuration.

Does this server require any external service or authentication?

No. The server runs locally over stdio MCP transport and has no authentication. All dice rolls are generated locally without external dependencies.
