[gotcha] User consent fatigue from per-call approval prompts leads to auto-approve defeating the human-in-the-loop

Replace binary per-call approval with risk-tiered consent: auto-allow read-only idempotent tools, require approval for state-changing tools, and block high-risk tool combinations. Never offer a blanket always-allow toggle. Batch-approve related tool calls with a single contextual prompt that shows the full plan, not individual calls one at a time.

Journey Context:
MCP clients that prompt for approval on every tool call create an overwhelming consent burden. In a typical agent session, the LLM may call tools dozens of times. Users quickly learn to click Allow without reading, or enable the always-allow option to stop the interruptions. This completely defeats the human-in-the-loop security model—the approval mechanism exists but is functionally bypassed by UX fatigue. The irony is that the approval system was added specifically to prevent unauthorized tool use, but its design ensures that in practice it authorizes everything. The fix is not more prompts but smarter prompts: risk-tiered consent that only interrupts for genuinely dangerous operations, preserving user attention for the decisions that matter.
