What is the Random Number MCP MCP server?

Random number mcp mcp server connects Random Number MCP to AI assistants that speak the Model Context Protocol. Essential random number generation utilities from the Python standard library, including pseudorandom and cryptographically secure operations for integers, floats, weighted selections, list shuffling, and secure token generation.

What Random Number MCP does

Essential random number generation utilities from the Python standard library, including pseudorandom and cryptographically secure operations for integers, floats, weighted selections, list shuffling, and secure token generation.

Tools it exposes

Once connected, the assistant can call these 10 tools directly:

  • random_int — Generate random integers
  • random_float — Generate random floats
  • random_choices — Choose items from a list (optional weights)
  • random_shuffle — Return a new list with items shuffled
  • random_sample — Choose k unique items from population
  • secure_token_hex — Generate cryptographically secure hex tokens
  • secure_random_int — Generate cryptographically secure integers
  • Prerequisites — The Prerequisites tool exposed by this server
  • Setup — The Setup tool exposed by this server
  • Building — The Building tool exposed by this server

Installing the random number mcp mcp server

The server is distributed via npm as @modelcontextprotocol/inspector, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Requirements

  • Python 3.10+ - uv package manager

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Random Number MCP sits in that group, and the shape of its toolset — random_int, random_float, random_choices among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • With 10 tools exposed, expect a noticeable bump in prompt size — disable it in projects that never use Random Number MCP.
  • Maintained by zazencodes, written in Python.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the random number mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

Frequently asked questions

It connects Random Number MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 10 tools (random_int, random_float, random_choices, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Random Number MCP directly.
