Desktop app ignores selected LLM provider and always tests against LM Studio (127.0.0.1:9200) after PR #349

Issue Type

Browser Issue

Operating System

macOS

Description

After PR #349, the BrowserOS desktop app appears to ignore the selected LLM provider at runtime. Even when a provider is configured as Gemini, clicking Test always sends the request to http://127.0.0.1:9200 (LM Studio).

This makes Gemini (and other non-LM-Studio providers) unusable in the desktop app unless LM Studio is running locally.

Notes

Deleting and recreating the provider does not change behavior

The issue appears to be caused by changes in PR #349

The Test button seems to use a fixed runtime client rather than the selected provider

Steps to Reproduce

• Launch BrowserOS desktop app

• Ensure LM Studio is not running

• Create a new Gemini provider

• Base URL: https://generativelanguage.googleapis.com/v1beta

• Enter Valid API key

• Save and click Test

Expected

Test request is sent to the configured Gemini base URL.

Actual

Test request is sent to:

http://127.0.0.1:9200

Resulting in:

Failed to fetch (127.0.0.1:9200)

Additionally, I assume also related to PR #349, the BrowserOS MCP server port changed to 9100 when updating to 0.39.0.3. This is a breaking change for any agents relying on the browser and such changes in the future should be treated as such.

@Jaribeau can you please share what do you see as server URL? We added a newproxy port right in the chromium to avoid all agent port issues. It all agent request now go through the proxy port.

Hmm also seems to work fine for me. Can you please try restarting the browser?

Here's the new MCP server url:

Before the update it was at port 9100.

On the providers:
Restarting was of course the first thing I tried when I was trying to fix this last week.

Not sure what happened now, as I haven't touched anything since -- but my previously setup providers are gone.

I added the gemini provider back, and it is working now 🤷‍♂️:

Thanks for reporting! This should be resolved in recent releases. If you're still seeing this on v0.41.0, please reopen!
