MCP Random Number

MCP Random Number is an MCP server that provides true random numbers derived from atmospheric noise via random.org. Large language models often struggle to produce unbiased random values due to their probabilistic token generation, which results in predictable distribution patterns. By connecting AI assistants to random.org, this server eliminates algorithmic skew and pseudo-random limitations in AI workflows. Developers, researchers, and AI tool users employ this integration whenever applications require genuine physical entropy rather than pseudo-random approximation. The tool enables clients to request true random values on demand for tasks like randomized testing, cryptographic seeding, statistical sampling, and fair decision-making processes. By wrapping atmospheric entropy in the Model Context Protocol, it allows compatible clients such as Claude Desktop to reliably delegate number generation to a verified physical source, avoiding the typical distribution clustering seen in standard model outputs.

How to install and configure MCP Random Number

Follow these steps to install and configure the server: 1. Clone the repository and navigate into the project directory: bash git clone https://github.com/maxbogo/mcp-random-number.git cd mcp-random-number 2. Install dependencies and compile the project: bash npm install npm run build 3. Add the server configuration to your MCP client settings file (such as Claude Desktop), replacing /ABSOLUTE/PATH/TO/ with the actual path to your repository clone: json { "mcpServers": { "mcp-random-number": { "command": "node", "args": ["/ABSOLUTE/PATH/TO/mcp-random-number/build/index.js"] } } }

What you can do with MCP Random Number

• Generating true random numbers from atmospheric noise during automated test suite runs to avoid pseudo-random sequence bias. - Sampling unbiased subsets from datasets or participant pools for research experiments through conversational AI assistants. - Selecting fair winners or assignees in lotteries, giveaways, and decision-making workflows managed directly within chat interfaces. - Providing physical entropy seeds for non-cryptographic modeling simulations executed by agentic coding tools. - Comparing model-generated random distribution outputs against verified atmospheric entropy benchmarks for statistical analysis.

How do I install MCP Random Number?

To install the server, clone the repository from GitHub using git clone, navigate into the created directory, run npm install, and then run npm run build. Once built, register the absolute path to build/index.js under your MCP client configuration using the node command.

What can MCP Random Number do?

The server enables AI assistants to request true random numbers generated from atmospheric noise via random.org. This allows connected language models to bypass their internal distribution biases and provide authentic random values for statistical tasks, sampling, and decision-making.

Why use random.org instead of standard LLM generation?

Language models do not generate true random values and frequently show distribution biases when asked for random numbers. Connecting to random.org ensures the generated numbers rely on physical atmospheric entropy rather than pseudo-random algorithmic predictions.

Which MCP clients work with MCP Random Number?

Any client supporting the standard Model Context Protocol can connect to this server, including Claude Desktop and compatible developer tools. The server runs locally using Node.js and communicates via standard MCP protocol definitions.
