MCP Setup fails with LM Studio?

problem

It seems LM Studio doesn’t open an OAuth browser instance for MCP authorization:

So how is it expected to work with oauth login? How does it work with any mcp server? You have to pre register an access token and feed it in manually?

I haven’t used any other MCP servers with LM Studio (https://lmstudio.ai) that require OAuth - all others are local or use a pre-generated token.
