When one of their tools returns a result, that result can carry extra metadata alongside its content. Claude Code now keeps a result with empty content if it carries that metadata. Before, only results with non-empty content were kept.\n\n**Why**\n\nMCP tool results that carry only metadata are no longer thrown away.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
