The JWT + MCP integration is the real insight here. Most agent auth systems treat payments and identity as separate concerns, but tying both to a single token means you can express fine-grained capabilities directly in claims—rate limits, spend caps, request signatures—without a separate policy layer. POW for humans is clever UX (no friction), but the Lightning side only works if settlement is subsecond; any latency on verification becomes a denial vector at scale.
