What
MCP (Model Context Protocol, the standard Claude Code uses to connect to external tool servers) tool entries are now checked for a 'needs-auth' status. 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.
Why
This lets Claude Code notice and surface MCP servers that require authentication before their tools can be used, rather than silently leaving them unusable.
