When Claude Code runs headless (without the interactive screen), it can wait at start-up for the servers named in `CLAUDE_CODE_MCP_PREWAIT_SERVERS` to be ready. That wait can now be told to leave some servers out, and it then holds only for the remaining named servers. Before, it waited on every named server until the deadline.\n\n**Why**\n\nStart-up spends less time waiting on servers that do not need to be held for.\n\n- Area: Headless Mode\n- Names: `CLAUDE_CODE_MCP_PREWAIT_SERVERS`\n- Tier: Use it now\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
