RPG Generator MCP Server

What is RPG Generator MCP Server?

A Model Context Protocol (MCP) server built with TypeScript that generates random tabletop RPG content—campaign ideas and fantasy region attributes. It allows LLMs (like Claude) to use two specialized tools to spark creativity by forcing connections between unrelated elements.

How to use RPG Generator MCP Server?

Requires Node.js and npm. Clone the repository, install dependencies, build, then configure the server in Claude Desktop's claude_desktop_config.json (command: rpg-generator-mcp-server). After restarting Claude, ask prompts such as “Generate a random campaign idea for my TTRPG” or “I need some random regions for my fantasy world”. You can also test with the MCP Inspector via npm run inspect.
