  }
}

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

  • "What pixel dimensions do I need for a poker card face image?"

Limitations

  • Rate limits — The server enforces 3 requests/second to TGC (below their 4/sec limit) with per-session budgets of 500 reads and 200 writes.
  • Authentication — Uses environment variable credentials only. OAuth 2.1 support is planned for a future release with HTTP transport.
  • 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 only. HTTP/SSE transport planned for v2.
  • Read-only catalog — The component catalog and pricing come from TGC and cannot be modified.
