If the transport http is not recognised, update langchain-mcp-adapters. A 401 error means the app key is wrong or missing.
Hand over a running session
Choose “Hand off to an agent” in the Guard.ch viewer and paste the prepared prompt into your assistant’s chat. The session ID in that prompt lets the assistant continue in the same browser. Sign your assistant in with the same Guard.ch account.
