Some sessions get MCP servers supplied by Claude Code's cloud service, which holds their sign-in. Before, trying to sign in to one of these started the usual login flow.\n\nClaude Code now shows a message instead. It says the server is provided to the session by Claude Code's cloud service, so it cannot be signed in to from here. It tells you to reconnect the server under Settings \u2192 Connectors on claude.ai and then start a new session.\n\n**Why**\n\nA login that could never succeed is replaced by steps that work.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
