A tool call that runs long can become a background task, which keeps running while you carry on. When the server sends progress updates for such a call, Claude Code now shows them on the task's status line, at a limited rate. The status shows:\n\n- A percentage, when the server says how much work there is in total\n\n- Otherwise the server's own status message\n\n- Otherwise \"Processing\u2026\" followed by a count\n\n**Why**\n\nLong MCP calls in the background now show live progress instead of a status that never moves.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 1\/5"}
