When a request to one fails, Claude Code decides whether to try again. One more kind of error is now treated as final, so Claude Code does not retry after it.\n\n**Why**\n\nThis may cut out repeated attempts that were never going to succeed.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
