The check for whether a server's older sign-in was refused, for example one from a plugin, now needs a further remote check to pass and has extra conditions. Claude Code also gained a new label, `cc-plugin-privacy`. The error saying a server's connection was closed while signing in again now uses shared wording.\n\n**Why**\n\nThis could change when an MCP server is shown as needing you to sign in again.\n\n- Area: MCP\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
