MCP Random Number

An MCP (Model Context Protocol) server that provides true random numbers from atmospheric noise via random.org.

Why?

LLMs struggle with generating truly random numbers. This chart shows the distribution bias of 100 random numbers (range 1-100) from 3 popular LLMs:

  2. Connect to the MCP server:

    Add the below json to your configuration with the appropriate /ABSOLUTE/PATH/TO/ value:

    {
      "mcpServers": {
        "mcp-random-number": {
          "command": "node",
          "args": ["/ABSOLUTE/PATH/TO/mcp-random-number/build/index.js"]
        }
      }
    }
