Hey Product Hunt! 👋 I'm the maker of run.pay. The idea came from a simple observation — Stripe just released Agent Toolkit, meaning AI agents can now spend money autonomously. But there was nowhere for them to spend it. run.pay is the marketplace I built to fill that gap. Agents discover services via MCP, Stripe charges per call automatically, sellers get paid via Connect. Zero human intervention after setup. Tech stack: Node.js + PostgreSQL on Railway, Stripe Connect + Agent Toolkit, MCP protocol, Resend for emails.

What services would you want your agent to buy automatically? 🚀
