📜 Description

The mcp-chat plugin displays an error message indicating that the provider apparently doesn't work. Strangely the chat still works. This message confuses users.

• @backstage-community/plugin-mcp-chat-backend: 0.8.0

Could be related to: #8297

👍 Expected behavior

No error message should be visible

👎 Actual Behavior with Screenshots

Provider is working but an error message is visible

Hey there,
I can see that you are using Azure OpenAI.
My educated guess is that the endpoint that the plugin calls during connection testing is not compatible with Azure OpenAI.
If you take a look at the Azure OpenAI documentation, you can see that the endpoint for listing model is different.

@Lucifergene based on this and #8387, I suppose it can make sense to separate "pure" OpenAI and Azure OpenAI providers.
I can help with that by creating a PR!
