Creating an mcp server at n8n and calling it from openai playground, it doesn’t get recognized by openai. is there a problem with n8n MCPs recognition by openAI?

Hi, how is your configuration in openai?
Hey,
so if ure using test url, it seems MCP from openai playground will be making multiple calls, to using test in this instance will likely fail,
Have you tested with production URL? is it same thing? What your setup? I assume you have a domain linked? So playground can access it
I tried with both test and production and no call is received by openai in my n8n instance. Is there anyone who ever managed to connect them? The n8n mcp server should be compatible straight forward eith openai… and this would be a major feature to support…

Hey,
I think you can try access the sse endpoint in postman, you should get this
It’s working good with the production URL, calls my n8n sse endpoint all okay, I mentioned test URL as this may cause issues if used, it’s likely with openai it could be host being blocked or something else, confirming via postman helps to check this connectivity. are you self hosting or hosting in n8n cloud?
Here are some screenshots showing, I think it might be some network issue you’re facing.
OpenAI just launched Deep Research API that support MCP
I just tired to add MCP server from n8n, and this error shown

I also tried adding n8n MCP servers via Chatgpt Connectors and it also says the mcp server is not compatible.
I created a feature request here and via email.
Agree that supporting this would be huge and using n8n mcp servers as part of openai api calls or chatgpt would be great.
