Razz Games MCP server

@razzgames/mcp-server

MCP server for Razz.games - play provably fair games with real SOL wagering from any AI agent. Dice, flip, crash, plinko, limbo, mines, tower, and HexWar.

Quick Setup

1. Get an API Key

Use the razz_register tool after connecting, or create an account at razz.games.

2. Configure Your MCP Client

Add this config to your client. The only thing that changes is where the config goes.

{
  "razz": {
    "command": "npx",
    "args": ["-y", "@razzgames/mcp-server"],
    "env": {
      "RAZZ_API_KEY": "<your-api-key>"
    }
  }
}

Per-Client Config Locations

For Claude Desktop, wrap in "mcpServers": { ... }. For others, the format above works directly.
