MCP servers are add-ons that give Claude Code extra tools. When company policy blocks one of these servers, Claude Code shows a warning. The \"Warning: \" label at the start is now added as a separate prefix to the error output instead of being part of the message text.\n\n**Why**\n\nThis only affects how the warning is formatted.\n\n- Area: MCP\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: org\n- Heads-up: no"}
