hmm, it seemed to be an intermittent issue on Google's side it seems.

I'm seeing it now with all models.

Hi,

Even if it's closed, I would like to give some details.

Some models don't support stdio MCP servers.

Disable all your MCPs in your configuration file, then enable them one by one to check if your opencode is responding.

I found out that I was using a MCP server using stdio protocol, which wasn't compatible with the new Gemini models!

Disabling this MCP server gave me those models back!

edit: it seems obvious to proceed like this, but at least it is written :)

@jacquesbh it shouldn't have anything to do with stdio, but it does have to do with tool schemas, we need better sanitization of tools
