Some of those tools start a task on the server that Claude Code can move to the background while work goes on.\n\nThere is now a limit on how many such tasks can be moved to the background between your messages. Once it is reached, a new task is not moved. The tool tells Claude that a cancel was sent and no result will follow. This continues for further tasks until you write again.\n\n**Why**\n\nClaude sees a clear refusal and the reason for it, and background MCP tasks cannot pile up without bound while you are not replying.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: yes"}
