GameDev MCP Hub

Version: 0.1.0 · Status: active development

MCP hub that aggregates game-development MCP servers (Blender, Godot, GitHub, Obsidian, …) behind one interface for Claude, LM Studio, Cursor, and other MCP clients. Includes a local GUI, smart task routing, and SSE multi-client support.

Quick start

Prerequisites: Node.js 20+

# Install
pnpm install   # or: npm install

# First-run config (.env, hub-config, mcp-servers)
pnpm setup     # or: npm run setup

# Edit secrets / enable servers
#   .env
#   config/mcp-servers.json

# Multi-client SSE hub + GUI (recommended)
pnpm start:sse   # after: pnpm build
# or: ./scripts/start.sh

• MCP SSE: http://127.0.0.1:3000/sse

• GUI: http://127.0.0.1:3100 (port auto-scans 3100–3109)

• Stdio mode (single client): pnpm start

Windows: scripts\start.bat or START_ALL.bat.

What works today

Enable servers in config/mcp-servers.json. Example configs ship as *.example.json.

Configuration

GITHUB_TOKEN and GITHUB_PERSONAL_ACCESS_TOKEN are both accepted; the hub mirrors them when spawning servers.

By default HTTP/SSE/GUI bind to 127.0.0.1. Set security.bind_localhost_only: false only if you understand the risk. Set security.require_authentication: true and HUB_API_KEY to protect GUI mutation endpoints.

Scripts

pnpm build          # compile + copy GUI assets
pnpm start          # stdio transport
pnpm start:sse      # SSE multi-client
pnpm test           # unit tests
pnpm type-check
pnpm lint
