A new helper filters down to tools that need authentication and haven't already been handled, and surfaces an `mcp_needs_auth` signal listing the affected server names when any are found.\n\n**Why**\n\nThis lets Claude Code notice and surface MCP servers that require authentication before their tools can be used, rather than silently leaving them unusable.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 2\/5"}
