For a Streamable HTTP MCP server with Oauth, goose runs the user through the entire Oauth flow every time they start a new chat session.

Example:

1. Install streamable http server with oauth such as https://docs.onkernel.com/mcp
2. Complete oauth flow
3. start chat session → this puts you through oauth flow again!

Even get this error when attempting to re-auth:

Error
Authentication already completed.
