Our hands-on result: Partial 5 of 7 tasks passed, tested Oct 22, 2026 with MCP TypeScript SDK (reference client).
ChatGPT setup
https://mcp.formada3d.com/- Open Plugins on chatgpt.com, click the plus button, then Add custom MCP server. On some plans you first turn on Developer mode under Settings.
- Name it com-formada3d-mcp and enter the URL: https://mcp.formada3d.com/
- Set authentication to none.
- Tick the risk acknowledgement, create it, then start a new chat and pick it with @.
We ran the hands-on test in a reference client, not in ChatGPT. This config follows ChatGPT's documented format for remote (Streamable HTTP) servers. If it fails for you, tell us and we will retest.
