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"]
}
}
}
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.
flip_coin
Flip a coin with configurable number of sides. Optional 'sides' parameter (default: 2). Returns 'Heads' or 'Tails' for 2 sides, 'Heads', 'Tails', or '_' for 3 sides, and 'It landed on side X' for n>3 sides.

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