Mythx Engine MCP Server

A complete tabletop RPG engine your AI can run: deterministic dice, five-tier outcomes, FitD-style stress, combat tracking, situation clocks, investigations, NPC relationships, world generation - 134 tools over the Model Context Protocol, with four complete starter worlds bundled in. It runs locally over stdio via the published package.

People connecting gaming tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

Claude Code

claude mcp add protolabsai-mythx-mcp -- npx -y @mythxengine/mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "protolabsai-mythx-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@mythxengine/mcp-server"
      ]
    }
  }
