I’m using ngrok to tunnel my IDA Pro MCP server to connect to ChatGPT but it doesn’t seem to work. Keep showing Error creating connector (The image is attached above). I have tested this MCP server with CURL both local and ngrok URL but it was still working. What should I have to do now?
Welcome to the forum!
The category for your post is API, by chance is this really for Codex?
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.
Hi @il2dottore
Thanks for sharing the details. Since the MCP server is reachable both locally and through the ngrok URL via CURL, it does sound like the tunnel itself and the server endpoint are working correctly.
At this point, the best next step would be to reach out to OpenAI Support so they can investigate why the connector creation flow is failing on the platform side.
Once you’ve done that, please share the support case ID here as well so I can take a look internally from my side.
