What
Claude Code now shows a distinct error message when a tool from an MCP server (a connector that lets Claude use external tools and data) isn't available for the current session: "[server]'s MCP tools are not available in this session right now; [tool] did not run." This is separate from the existing message that suggests the server may have disconnected.
Why
This gives a clearer, more specific explanation for a case where MCP tools simply aren't usable right now, rather than lumping it in with a message that implies a connection problem.
