The Game Crafter

The Game Crafter MCP Server

An MCP server that connects AI assistants to The Game Crafter API, letting you design, manage, and price tabletop games through natural conversation.

Browse the component catalog, create game projects, add card decks and boards, upload artwork, and get instant pricing estimates — all through your AI assistant.

Who it's for

Indie board game designers, tabletop creators, and TGC users who want to manage their projects through an AI assistant instead of navigating the TGC web interface manually.

Prerequisites

• Node.js 18 or later
• A TGC account — sign up here
• A TGC API key — generate one here

Installation

Option 1: Remote (hosted on Apify) — no install needed

Connect to the hosted server at:

https://chillbot3000--tgc-mcp-server.apify.actor/mcp

No local setup required. Provide your TGC credentials when you call the authenticate tool. Usage is billed per operation via Apify's pay-per-event model (~$0.09 per typical session).

Also available on Glama Connectors.

Option 2: Local (via npx)

Add the server to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "thegamecrafter": {
      "command": "npx",
      "args": ["-y", "@alex-gon/tgc-mcp-server"],
      "env": {
        "TGC_API_KEY_ID": "your-api-key-id",
        "TGC_USERNAME": "your-tgc-username",
        "TGC_PASSWORD": "your-tgc-password"
      }
    }
  }
}

Restart Claude Desktop. The server will be downloaded automatically and appear in your MCP connections.

git clone https://github.com/alex-gon/thegamecrafter-mcp-server.git
cd thegamecrafter-mcp-server
npm install && npm run build

Then use "command": "node" and "args": ["/absolute/path/to/dist/index.js"] in the config above.

• Authentication — Credentials can be passed as authenticate tool parameters (required for remote usage) or via environment variables (for local stdio). OAuth 2.1 support is planned for a future release.
• File uploads — Maximum 50 MB per file. Images must be between 50x50 and 10,000x10,000 pixels. Supported formats: PNG, JPG, GIF, BMP, TIFF, SVG, WebP, PDF.
• Transport — Stdio for local usage. Remote HTTP available via the hosted Apify endpoint.
• Read-only catalog — The component catalog and pricing come from TGC and cannot be modified.
