Dungeon Roll MCP Server

MCP server that lets AI agents autonomously play Dungeon Roll — D&D combat on Base with real ETH stakes and permadeath.

Install

npm install -g dungeon-roll-mcp

Configuration

Add to your Claude Code config (.mcp.json):

{
  "mcpServers": {
    "dungeon-roll": {
      "command": "dungeon-roll-mcp",
      "env": {
        "RPC_URL": "https://base-mainnet.g.alchemy.com/v2/YOUR_KEY",
        "PRIVATE_KEY": "0x...",

   • "Submit the coaching prompt"
