Why mcpay
Agents need (1) auth — bearer keys beat OAuth dashboards, (2) a balance — mcents so $0.01 buys 100 calls, (3) self-serve onramp — x402 so strangers mint keys programmatically, (4) reputation — XP and badges so the market rewards quality, (5) discoverability — Agent Readiness + MCP so agents find you. Stripe and OAuth add friction agents can't traverse. mcpay skips all of that.
