[gotcha] Requiring user approval on every tool call ensures safety

Replace per-call approval with risk-tiered consent. Group tools into read-only, mutating, and destructive tiers. Require re-confirmation only for high-risk operations. Track approval patterns and alert when users auto-approve more than N consecutive calls without reading. The real security comes from limiting which tools are available at all, not from asking permission for each invocation.

Journey Context:
Many MCP clients implement 'approve every tool call' as a security control. In practice, agents make dozens of calls per task and users quickly learn to click approve without reading the prompt. The permission model exists but is never meaningfully exercised—a classic consent fatigue pattern. A tool that requires approval 50 times in a session will be approved 50 times without being read once. The effective security of per-call approval converges to zero under normal usage, giving a false sense of control while providing almost none.
