Error creating connector when trying to connect MCP server on website

Hi,

Based on your post and screenshot, this looks to me more like a ChatGPT custom MCP connector/app setup issue than a regular OpenAI API endpoint issue.

If it is that, then I found this relevant Help Center doc that you can double check:

https://help.openai.com/en/articles/12584461-developer-mode-and-mcp-apps-in-chatgpt-beta

A few things worth checking from that doc: whether Developer Mode/custom MCP apps are enabled for your workspace, whether your plan/workspace supports creating them and whether you have the right admin/developer permissions.

If the connector creation UI itself keeps returning “Something went wrong,” I’d contact OpenAI Support through the Help Center and include the screenshot, approximate time, workspace/account type, region, connector settings and server logs.

An important side note: since this is a custom MCP server exposed through ngrok, I’d be careful about posting the full URL publicly. OpenAI’s docs note that custom MCP apps/Developer Mode can introduce security risks, including prompt injection, unintended actions, destructive actions or malicious MCPs attempting to steal information.
