MCP Elicitation: Structured Mid-Task Human-in-the-Loop Input Without Workflow Interruption

Added in Claude Code 2.1.76, MCP Elicitation lets a running MCP server pause execution and request structured user input via JSON Schema-validated form fields or a browser URL, then continue with the response, all without restarting the workflow. New Elicitation and ElicitationResult hooks let operators intercept, override, or auto-fill responses programmatically, enabling patterns like config resolution mid-task, OAuth flows, and progressive data gathering. This eliminates the common failure mode of agents making silent assumptions when given ambiguous inputs.
