Coin Flip MCP Server

An MCP server that provides true random coin flips using random.org's randomness API. This server demonstrates the Model Context Protocol by providing a tool for generating random outcomes with configurable sides.

Features

Tools

  • flip_coin - Flip a coin with configurable number of sides
    • Optional sides parameter (default: 2)
    • Uses true randomness from random.org
    • Special handling for edge cases (0, 1, or negative sides)
    • For 2 sides: Returns "Heads" or "Tails"
    • For 3 sides: Returns "Heads", "Tails", or "_"
    • For n>3 sides: Returns "It landed on side X"

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "coin-flip": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-coin-flip"]
    }
  }
}

Example Usage

Once connected to an MCP client like Claude Desktop, you can use natural language to interact with the coin flip tool. For example:

  • "Flip a coin"
  • "Roll a 6-sided die"
  • "Give me a random number between 1 and 20"

The server will use true randomness from random.org to generate the result.

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector:

npx @modelcontextprotocol/inspector node build/index.js
